Description

Programmable display, programmable controller system, program

The present invention relates to a programmable display or the like.

The programmable display is generally connected to various connected devices such as a PLC main body or a temperature control device, and displays items such as numerical display or lighting for performing status display of such connected devices, or An image of an item such as a switch that allows the user to give an arbitrary instruction. In addition, the item is also referred to as a screen member or the like. On a screen of a programmable display (referred to as an operation display screen), an image of a plurality of screen members (items) is usually displayed. The information for displaying such an operation display screen (referred to as a screen material or the like) is arbitrarily created by a developer or the like in a support device or the like, and is downloaded from the support device to the programmable display.

In the above-mentioned screen data, each of the above-mentioned items includes an image of the item (an image of a switch or an image of a light) and a display position coordinate, and further includes an external memory set to be described later. Information such as the address of the area (allocation memory address). Further, there are cases where some programs are included. The above supporting device, for example, There is a function of performing various kinds of support for the user to arbitrarily create the above-mentioned screen data. In this regard, since it is an existing technology that has been known, it is not particularly described herein.

Each of the above-described items (screen members) is associated with an arbitrary component of an arbitrary connected device, and displays the state of the component or receives an ON/OFF instructor of the component. For example, when it is an item for numerically displaying the temperature measurement value of the temperature adjustment device, the current temperature is displayed by the numerical value at any time. Or, if it is an item that lights up the ON/OFF state of the temperature adjustment device, if the temperature adjustment device is in the ON state, the display is turned on, and if it is in the OFF state, the display is turned on and off. .

In addition, in the support device, a light bulb lighting image and a light bulb light-off image are registered in advance as a project image, and in the screen data, a light bulb lighting image and a light bulb lighting image are included for one light bulb item. Of course, it is not limited to the case of a light bulb, and is also the same for other types of items (such as switches).

The display control relating to the above various items is realized by, for example, periodically performing predetermined processing for each of the above items. The predetermined processing is, for example, a stored data of a predetermined memory area of a predetermined memory device (which is an external memory device) associated with a predetermined connected device of the item (represented by the above-mentioned allocated memory address) The process of storing the stored data in the memory area). Further, it is a process (display content update process) for determining and displaying the display content of the item based on the stored data. In addition, the above-mentioned points will be The processing for reading the stored data in the memory area is generally referred to as the external memory access processing. Therefore, there is also a case called external memory access processing.

Further, the connection device updates the stored data of the predetermined area of the external memory device at any time (for example, in the above-described temperature adjustment device, the temperature measurement value is updated at any time).

Here, the above-mentioned support device also has a function of allowing the user to arbitrarily set the address of the allocated memory for each of the items. As in the above, in the picture material, the allocated memory address is also included. The screen data is downloaded from the support device to the programmable display and memorized. Thereafter, in operation, each of the items is associated with each other, and the allocated memory area is accessed based on the allocated memory address.

However, as in the above, since the allocation memory address is set by a person, there is often a possibility that a setting error occurs. When the screen material is downloaded to the programmable display and memorized (when the medium period is used), the setting error is detected. In the prior art, the user is allowed to perform the allocation memory position on the side of the supporting device. Site corrections and changes. Of course, after the correction or change operation, the screen data including the changed allocated memory address is transmitted to the programmable display and re-remembered.

Here, the prior art described in Patent Document 1 is known.

The invention of Patent Document 1 is an editing device (corresponding to the above support) At the device, a function of setting and changing the relevant address (the above-mentioned allocated memory address) of each component (corresponding to the above-mentioned item) is realized, and an editing device capable of easily changing the address is realized.

[Patent Document 1] Japanese Patent Laid-Open Publication No. 2010-108220

As described above, in the prior art, even when the picture data (the allocated memory address) that has been memorized on the programmable display side is corrected or changed, it is necessary to perform correction at the side of the support device. Change the job. Therefore, particularly in the case where the programmable display and the support device are installed at places distant from each other, it becomes very troublesome. Also, there is a possibility that a setting error will occur.

An object of the present invention is to provide a method for correcting or changing screen data (which is assigned a memory address or the like) that has been stored on the programmable display side on the programmable display side. Programmable display for the burden of work.

The programmable display of the present invention is a programmable display to which one or more connected devices are connected, and has the following configurations.

. Corresponding to each of the items on the display screen, and memorizing the item information memory means representing the access information of the access target; An item display means for obtaining information from the access target based on the access information of the item information memory means, and displaying the item using the obtained data; The aforementioned access information for items related to any of the changed objects Access information change means for arbitrarily changing.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is a schematic configuration diagram of the entire system including the programmable display 1 of this example.

In addition, the configuration shown in FIG. 1 is merely an example, and is not limited to this example. For example, it is not absolutely necessary to connect the programmable display 1 to the drawing editing apparatus 5 via a communication line. The programmable display 1 and the drawing editing device 5 may also exist independently of each other.

Further, the painting editing device 5 is provided with a function of the existing supporting device described in the above background art, and is provided to allow a developer or the like to arbitrarily create the operation display screen to be programmable. A function such as information (such as screen data) on the display 1 to support it. However, the drawing editing device 5 of this example has a function to be described later in addition to the functions of the existing supporting device. The details will be described later.

Further, in the programmable controller system having the configuration shown in FIG. 1 or FIG. 3, the programmable display 1 is connected to the drawing editing device 5 via the communication line 3, and may be configured in the programmable display 1. use The configuration at the place is not limited to this example. For example, as another example, the configuration shown in FIG. 1 or FIG. 3 can also be considered as a display for the configuration at the manufacturing site of the programmable display 1.

In the case of the above-described other example, for example, when the hardware of the programmable display 1 is finished on the manufacturer side, when the software/firm body is mounted on the programmable display 1, the drawing editing device is 5 is connected to the programmable display 1. Thereafter, for example, for each of the programmable displays 1, a developer or the like can arbitrarily create arbitrary screen data on the drawing editing device 5. After that, the created picture data is downloaded to the programmable display 1 and memorized. Further, at each of the programmable displays 1, the corresponding communication program is downloaded from the drawing editing device 5 and memorized.

Further, the drawing editing device 5 is a case in which a communication program corresponding to each of the connected devices 4 is previously memorized from the prior art. As a specific example, the drawing editing apparatus 5 may have a case where more than 100 communication programs are previously memorized. After that, the developer or the like selects a communication program corresponding to the connection device 4 that is scheduled to be connected to each of the programmable displays 1 from the above, and downloads it to the programmable display 1 (for example, reference document (Japan Kaiping) Bulletin No. 7-225831)).

In the prior art, the programmable display 1 in which the screen data and the communication program downloaded from the drawing editing device 5 are stored is shipped to the shipment destination and is set to be used. At the object of shipment, the connection device 4 of any one or more types is connected to the programmable display 1. As above, in the picture material, although The above-mentioned allocated memory address for accessing the above-described external memory device in the connected device 4 is included, but there is a case where an error occurs in the address setting or the like.

The corresponding method of the prior art for such a case is reset as shown in the figure above on the side of the drawing editing apparatus 5. On the other hand, in the present method, the user can change (reset) the allocated memory address at the programmable display 1 (in other words, at the destination of shipment), and the workload can be reduced. Further, at this time, it is possible to prevent the user from making a setting error. In this regard, for example, it is realized by using "memory address settable range data" 24 to be described later.

That is, as in the above, regarding the creation of the screen material and the communication program and the download itself, it can be regarded as slightly the same as the prior art. However, the drawing editing device 5 of the present embodiment is a type of "communication I/F driver 33" which will be described later by adding "memory address settable range data" 24 which will be described later to each of the communication programs. Memory and management. After that, the developer or the like selects "communication I/" corresponding to the connected device 4 connected to (or is intended to be connected to) each of the programmable displays 1 from among the various "communication I/F drivers 33". The F driver 33" is downloaded to the programmable display 1.

Here, as described above, since the connection device 4 connected to each of the programmable displays 1 has various types, it can be considered to be compatible with any connection device 4. "Memory address" corresponding to all types of connected machines 4 The settable range data 24 is pre-stored in the programmable display 1. However, as described above, since there are many types of the connection devices 4, it is desirable to memorize all the "memory address settable range data" 24 corresponding to all the connected devices in the programmable display 1 in advance. It is difficult. That is, in general, the programmable display 1 is inferior in hardware performance as compared with a personal computer or the like. Therefore, in the actual situation, it is possible to memorize all the "memory address settable range data" 24 corresponding to all connected devices in the drawing editing device 5 as a personal computer or the like, but in the case of It is difficult to program all of the memory in the programmable display 1.

In view of the above problem, in the present method, by using the "communication I/F driver 33" described above, it is possible to easily set only the "memory address settable range data" necessary for the programmable display 1 in advance. 24 for memory. The details will be described later.

In addition, it is assumed that all of the "memory address settable range data" 24 corresponding to all of the above-described connected devices can be stored in the programmable display 1 in advance, and of course, it is possible to obtain memory by this method. The effect of reducing the amount of data in the programmable display 1.

In addition, even when the configuration shown in FIG. 1 or FIG. 3 is provided at the application site of the programmable display 1, the burden of the operation of changing the address of the allocated memory can be reduced by the method, and further It is expected that there is an effect that the user setting error at this time can be prevented.

However, when the programmable display 1 and the drawing editing device 5 When the system is in a state of being apart from each other, the technique is particularly effective.

The programmable display controller system shown in FIG. 1 is provided with various connected devices 4 and a programmable display 1 connected to various connected devices 4 via a communication line 6. The various connection machines 4 are, for example, various PLC bodies or the above-described temperature adjustment devices.

Further, the programmable display 1 may be configured to be connected to the drawing editing device 5 via the communication line 3 (however, as described above, there is also a place where the drawing editing device 5 does not exist at the application site. Composition).

At the programmable display 1, there is a plurality of communication interfaces 2 (communication ports), and through various communication lines 3/communication lines 6 connected to the communication interfaces 2, and various connection devices 4 or drawing editing devices 5 Make a connection.

The drawing editing device 5 is provided with an existing function for supporting the developer or the like to arbitrarily create a material (screen material) for displaying the operation display screen on the programmable display 1. As for the function itself, as in the prior art, for example, various item images are prepared in advance, and the user repeatedly performs an operation of selecting a desired item image and arranging it at a desired position, and performing the above-mentioned picture data. Made. Further, for each of the items, setting of a desired allocated memory address (allocated memory area) or the like is performed. The above screen data is downloaded from the drawing editing device 5 to the programmable display 1.

The programmable display 1 displays the above-described operation display screen based on the screen material as in the prior art. Further, in the display, for example, the display content update processing is periodically performed. Therefore, the access to the allocated memory area associated with each item on the operation display screen is acquired, and the latest information is acquired, and the operation display screen of the content corresponding to the latest material is displayed. However, when there is a setting error related to the address of the allocated memory, etc., it will not be a normal display (other data will be read and displayed, or data cannot be obtained (when the address is not When there is a situation)).

In the prior art, in such a case, it is necessary to perform address correction (reset) by the drawing editing device 5. On the other hand, in this method, address correction (reset) can be performed on the programmable display 1. Further, it is possible to prevent the occurrence of a setting error at this time.

Further, the drawing editing device 5 is realized by, for example, a general-purpose computer (personal computer or the like). Therefore, although it is not particularly illustrated, it has a configuration of a general personal computer or the like. In other words, for example, a calculation processor such as a CPU, a memory device such as a memory or a hard disk, an operation unit such as a keyboard or a mouse, a display unit such as a display, a communication function unit, and the like are provided.

In the above memory device, a predetermined application is stored in advance, and the arithmetic processor realizes various functions of the drawing editing device 5 by executing the application.

Moreover, the programmable display 1 has a hardware composition It is a general composition. Therefore, the following is briefly explained with reference to FIG.

FIG. 2 is a hardware configuration example of the programmable display 1 of the present example.

The programmable display 1 has a function similar to the above-described prior art example in which display of each screen (operation display screen) is performed based on the above-described screen data or the like.

In the display processing of the operation display screen, the display content update processing described above is also included. That is, the external memory access processing (data acquisition processing from the allocation memory area) corresponding to each item on the screen is also included.

The programmable display 1 shown is provided with a display operation control device 10, a touch panel 18, a display 19, and the communication interface 2 described above.

The display operation control device 10 is formed by the CPU 11, the ROM 12 (flash memory, etc.), the RAM 13, the communication controller 14, the graphics controller 15, the touch panel controller 16, etc., and these systems are connected to the bus bar 17 connection.

The CPU 11 is a central processing unit (calculation processor) that controls the entire display operation control device 10. The CPU 11 performs various kinds of calculation processing of the programmable display 1 by executing an application (for example, the main program 21 to be described later) stored in advance in the ROM 12 (in particular, processing and functional block diagrams of the respective flowcharts to be described later) Various processing functions).

Moreover, in the ROM 12, the background technology is stored The screen data (the screen material 22 described later) described in the above. As described above, the screen data 22 is provided with various materials (images, display position coordinates, size, etc.) connected to the switches, light bulbs, and the like arranged on the operation display screen, or the above-mentioned distribution memory address. Wait).

Here, in the present method, the user can change the address of the allocated memory in the screen material 22 at the programmable display 1. Further, it is possible to prevent the occurrence of a setting error at this time. The setting of the allocation memory address is performed, for example, by "designation of an arbitrary connected device + designation of any external memory address + designation of any of the addresses". The setting error is, for example, a case where an external memory device that does not exist in the designated connected device is specified, or the specified address is not a predetermined range of the specified external memory device. The situation inside, etc. Alternatively, it may be the case that the specified connection machine itself does not exist at all (not connected to the programmable display 1). The details will be described later.

By the processing of the CPU 11, for example, the display target data configured based on the screen data 22 or the acquired data obtained by the external memory access is expanded (drawn) in, for example, the RAM 13 (or not shown). On the VIDEO RAM). The details will be described later. Based on this depiction, the graphics controller 15 is displayed on the display 19 to display the above-described operation display screen and the like. The display 19 is formed, for example, by a liquid crystal panel or the like, and is provided with a touch panel 18 so as to be superposed on the liquid crystal panel.

The detection result of the pressing operation (touch) position on the touch panel 18 by the operator or the like is introduced into the CPU 11 or the like via the touch panel controller 16 and analyzed. For example, it is analyzed based on the above-described display position coordinates and size of each item. For example, if the operator or the like touches the display position of the portrait of the switch, the CPU 11 or the like analyzes the operation of the switch.

Further, the communication controller 14 performs communication with the connection device 4 or the drawing editing device 5, which is a PLC main body or the like, or a temperature adjustment device, via the communication interface 2 (data transmission and reception, etc.) ).

In Fig. 3, the software composition diagram of the above system is shown.

In the programmable display 1, various programs/materials such as the main body program 21, the screen data 22, and the communication program 23 are stored, for example, in the ROM 12 (flash memory or the like). By causing the CPU 11 to read, execute, and reference such programs/data and the like, display control of each operation display screen for the programmable display or the like is performed.

This operation display screen is formed by the above-described numerical display, image display of various items such as a light bulb, a switch, and the like, and the display content of each item is, for example, a predetermined memory area for the external memory device from each connected device 4. The information (acquisition data) obtained in the (allocated memory area) is reflected and is updated at any time.

That is, the CPU 11 is based on the ontology program 21 and the screen. The data 22 and the acquired data are used to perform display control of the above operation display screen. At this time, the display content of each item (each screen member) on the operation display screen is reflected by the content of the acquired data (the numerical value display of temperature or the like, or the lighting/lighting of the light bulb, etc.). In addition, the function itself is an existing function and therefore will not be described in further detail.

The screen material 22 is, for example, a screen material file 32 which is arbitrarily created on the side of the drawing editing apparatus 5, and is downloaded to the programmable display 1 and stored. That is, the screen material 22 and the screen material file 32 can be regarded as substantially identical. In addition, hereinafter, it is assumed that the screen material file 32 is described as the screen material 22, and the screen data file 32 is not particularly distinguished.

Further, the communication program 23 downloads, for example, a communication program file 35 stored in advance on the drawing editing device 5 side to the programmable display device 1 and stores it. Here, the communication program file 35 is usually a plurality of people, and may also be called a communication program group. One or more types of communication programs of the communication program files 35 (communication program groups) are downloaded to the programmable display 1 and stored as the communication program 23.

Here, each of the communication program files 35 (various communication program groups) is prepared in advance in correspondence with communication protocols of various connected devices 4. Thereafter, the communication program file 35 corresponding to the connection device 4 (the communication protocol or the like) of the programmable display 1 connected to the download target among the various communication program groups is downloaded to the editable The display is at 1 position. Thereafter, it is stored as the communication program 23 described above.

The communication program 23 of the programmable display 1 is a program for communicating with the connection device 4 via the communication line 6. In general, each of the models of the connected devices 4 and the like has an inherent communication protocol, and communication between the programmable display 1 and the connected device 4 is performed in accordance with the communication protocol. Therefore, the communication program 23 needs to be separately developed for each model of each connected device 4. Further, of course, communication processing with the connected device 4 is realized by causing the CPU 11 or the like to execute the communication program 23.

As a connected device 4 such as a PLC main body, there are various manufacturers and models. In each of the manufacturers/models, there is a separate communication program, and the communication program is adapted to the connected device. The manufacturer/model of 4 is made into a plurality of types depending on the situation, and is stored in the drawing editing apparatus 5 as the majority of the communication program files 35.

The various communication program files 35 corresponding to the various connection devices 4 described above are stored in advance on the side of the drawing editing device 5 and the technology itself is downloaded to the programmable display 1 as an existing technology. However, in the present method, as shown in the figure, a communication I/F driver 33 is formed by adding a corresponding memory address settable range data 34 to each of the various communication program files 35. The form is stored and managed on the side of the painting editing device 5. That is, the "communication program file 35+ memory address can be set to a range of resources. The material 34" is called "communication I/F driver 33".

That is, various memory address settable range data 34 corresponding to various connected devices 4 are prepared in advance. Thereafter, the communication program file 35 and the memory address settable range data 34 corresponding to the same connected device 4 are paired to constitute the "communication I/F driver 33".

As described above, each of the communication program files 35 is a communication program that is created for each of the manufacturers/models. Therefore, the makers of the communication program files are the specifications of the connection device to be the communication target. Known. In particular, for example, it is a variety of information (for example, a device name, a memory unit, a numerical form, an address range (minimum, maximum), etc., which are described in advance in an external memory device connected to a communication device to be a communication target. In view of the above, the above-mentioned creator can create the above-mentioned memory address of the above-mentioned "various information relating to the external memory device in the connection device to be connected" for each of the connected devices. The range data 34 is set. After that, the created memory address settable range data 34 is stored and managed as the communication I/F driver 33 in pairs with the corresponding communication program file 35. At the drawing editing device 5, various (many) communication I/F drivers 33 corresponding to various (majority) connected devices 4 are stored.

Thereafter, from among the various (majority) communication I/F drivers 33, the communication corresponding to the connected device 4 connected to the programmable display 1 is downloaded for the programmable display 1 of any download target. I/F driver 33. This is memorized in the programmable display 1 as the illustrated communication I/F driver 25. As shown in the figure, the general communication I/F driver 25 is formed by the communication program 23 and the memory address settable range data 24. Of course, these are equivalent to any of the communication program file 35 and the memory address settable data 34.

In addition to the existing functions, the main body program 21 further includes a screen for changing the address of the allocated memory of the screen material 22 (not shown in FIG. 3, but is a window 90 or a dialog described later. The frame 100 and the like are displayed, and the user is allowed to input or select a desired address on the screen. Thereafter, the processing of updating the allocated memory address of the picture material 22 is also performed by the input/selected address. However, when there is a setting error, control is performed in such a manner that the allocation of the address of the memory is not performed (preventing the occurrence of an incorrect setting of the address). A more detailed description is made by a flow chart which will be described later.

Further, communication between the programmable display 1 and the drawing editing device 5 is performed, for example, by the main body program 21 and the drawing editor 31 (the communication function is incorporated in the drawing editor 31). In this regard, since it is not important, it is not illustrated and described.

As described above, in the HD (hard disk) not shown in the drawing editing device 5, the communication program file group 33 (a plurality of communication programs developed for each model) is stored in advance. Further, the drawing editing device 5 selects and designates any of the connected devices 4 by the drawing editor 31, and selects the connected device 4 The corresponding communication program file 33 is transmitted (downloaded) to the programmable display 1 and memorized as the communication program 23. The function itself is slightly the same as the prior art, but in this method, as in the above, it is not a separate communication program, but the communication I/F driver 33 is downloaded and memorized.

Thereby, the user only needs to perform the same operation as the prior art, and becomes the memory address settable range data 34 corresponding to the connected device 4 connected to the programmable display 1 of the download target. The ground is downloaded to the programmable display 1 and memorized. As a result, it is possible to store only the data necessary for the user to read the change of the address setting arbitrarily to prevent the occurrence of the setting error.

Further, the above-described program for realizing various processes such as access to the memory area and screen display, for example, may be included in the main body program 21 or may be included in the screen material 22. In any case, various operations of the programmable display 1 are realized by, for example, executing the program by the CPU 11 described above.

Here, the painting editor 31 of the drawing editing device 5 is also provided with a support function for allowing the user to create a desired operation display screen (the screen material). In this regard, as described above, various items prepared in advance are memorized in a hard disk or the like of the drawing editing apparatus 5. The various items are displayed in a list by the creation support function of the operation display screen obtained by the drawing editor 31, and the user selects the desired item and arranges it at a desired position. About this feature itself, Slightly the same as the prior art.

In addition, the drawing editing device 5 is, for example, a personal computer or the like, and is not particularly illustrated, but has a general-purpose computer (CPU, memory unit (hard disk, memory, etc.), and communication unit). , operation department (mouse, etc.), display). The processing function of the painting editor 31 is realized by causing the CPU to execute an application previously stored in the memory unit. The processing function itself of the drawing editor 31 is mostly the same as the prior art, and the difference is the memory data and download processing described above as the communication I/F driver 33. That is, the painting editing device 5 is not only an existing function but also has a new function as shown in FIG. These existing functions and new functions are realized by causing a CPU or the like (not shown) to execute an application program that is previously stored in a memory unit (not shown).

4 is a functional block diagram of the programmable display 1 of the present example.

The programmable display 1 of the present example is a programmable display to which one or more connected devices 4 are connected, and includes, for example, a project information storage unit 40, an item display unit 41, an access information changing unit 42, and connection device information. The memory unit 43, the communication unit 44, and the like. Further, the various functional units are realized by causing the CPU 11 to execute, for example, a predetermined application program that is previously stored in the ROM 12.

The item information storage unit 40 corresponds to each of the items on the operation display screen, and stores access information representing the access target. Accessing information, for example, as part of the screen material 22 News.

The item display unit 41 acquires data from the access target based on the access information of the item information storage unit 40, and displays the item using the acquired data.

Further, the item information storage unit 40 and the item display unit 41 may be regarded as existing configurations.

The access information changing unit 42 arbitrarily changes the access information of the item related to the arbitrary change target.

Further, the access information changing unit 42 can arbitrarily change the access information associated with the item to be changed, while preventing the occurrence of a setting error.

Here, for example, the access information is any address in any external memory device in any of the connected devices 4. The connected device information storage unit 43 stores memory information 43a including an address settable range of an external memory device connected to the programmable device 4 connected to the programmable display 1. One example of the memory information 43a is the settable range information 70 which will be described later.

Further, when there is a plurality of connected devices 4 connected to any of the programmable displays 1, the connected device information storage unit 43 stores the respective connected devices 4 of the plural number. Corresponding plural memory information 43a. Further, only the memory information 43a corresponding to the connected device 4 connected to the programmable display 1 is downloaded and memorized from the drawing editing device 5.

Thereafter, the access information changing unit 42 realizes the prevention of the occurrence of the setting error based on at least the address settable range (an example of which is an addressable range to be described later).

That is, the access information changing unit 42, for example, allows the user to input any new address, and will be connected when the new address is in the range of the corresponding address settable. The address in the access information of the item to be changed is changed to the new address. Thereby, it is possible to prevent the occurrence of the above-described setting error (for example, the first embodiment or the like described later).

Further, the access information changing unit 42 allows the user to input any new connected device, any new memory device, or any new address, for example. Thereafter, it is determined whether or not the memory information 43a corresponding to the new memory device of the newly connected device is stored, and it is determined whether the new address is within the address settable range in the memory information 43a. On the other hand, when the condition is satisfied, the connected device, the memory device, and the address in the access information of the item related to the change target are changed to the new connected device, the new memory device, and the new address. . By performing such an operation, it is possible to prevent the occurrence of the above-described setting error (for example, the first embodiment and the like described later).

Alternatively, the access information changing unit 42 may, for example, allow the user to select any of the addresses within the address settable range corresponding to any of the selected new connected devices and the new memory device. The new address. Thereafter, the address in the access information of the item related to the change target is changed to the selected new address. By doing this kind of exercise It is also possible to prevent the occurrence of the above-mentioned setting error (for example, the second embodiment described later).

Further, the access information changing unit 42 causes the user to select any of the new connected devices, for example, and presents one or more memory devices corresponding to the selected new connected device based on the memory information 43a. Thereafter, the user is allowed to select any of the new memory devices from the presented memory device. Further, the connection device or the memory device in the access information related to the item to be changed may be changed to the selected new connection device or new memory device (for example, the second embodiment described later) Wait).

Further, at the programmable display 1, for example, a communication program (communication program 23 or the like) and memory information 43a corresponding to each of the connected devices 4 connected to itself are stored. The communication unit 44 communicates with any of the connected devices 4 via the corresponding communication program 23. Further, the communication program 23a and the memory information 43a are downloaded and memorized from the support device (the drawing editing device 5).

Further, in the example shown in FIG. 4, the support device (writing editing device 5) includes a communication driver storage unit 45, a download unit 46, a setting unit 47, and the like.

The communication driver storage unit 45 stores various communication drivers (communication I/F driver 33, etc.), which are various communication programs (communication program files 35, etc.) corresponding to various connected devices. Each of them is additionally associated with the communication program The memory information 43a (memory address settable range data 34) of the connected device is formed.

The download unit 46 downloads the communication driver (for example, determined by the developer or the like) connected to the connection device 4 connected to the programmable display 1 of the download target among various communication drivers to the programmable driver. Display 1 and make it remember.

Further, the setting unit 47 allows the user to arbitrarily set the access information corresponding to any of the programmable displays 1. Thereafter, the download unit 46 downloads the set access information to any programmable display 1 and memorizes it.

Here, a specific example of the above-described screen material 22 and memory address settable range data 24 will be described.

5(a) and 5(b) are specific examples of the above-described screen material 22.

6(a), (b) and 7 are specific examples of the above-described memory address settable range data 24.

In the example shown in FIG. 5(a), the screen data 22 is composed of item type 51, coordinate 52, size 53, "data for each item type" 54, memory address information 55, and the like. Made into. Further, in each of the above items, information of each record shown in the figure is stored. Further, in Fig. 5(b), a detailed example of the above-described memory address information 55 is shown.

In the item type 51, item type identification information representing the type of the item (switch, bulb, numerical display, etc.) is stored. in In the "data for each item type" 54, for example, an image relating to the item is stored (for example, in the case of a light bulb item, a light bulb lighting image and a light bulb light-off image, or, if it is a switch item, It is an image of various items such as a switch ON image and a switch OFF image).

In the coordinates 52 and 53, information indicating the display position and size of the above-described item portrait on the operation display screen is stored.

Moreover, the memory address information 55 is information related to the external memory access processing, and includes the information of the allocated memory address and the like. Further, the setting data to be corrected and changed by the method is the memory address information 55.

In the example shown in FIG. 5(b), the memory address information 55 is provided with a memory mode 61, a memory access 62, a device name 63, an address 64, a data number 65, and the like.

The memory mode 61 is identification information of the connected device 4 that accesses the target.

The memory access 62 displays an access form (1 bit access, 16 bit access, etc.) to the external memory device represented by the device name 63.

The device name 63 is the identification information of the external memory device that accesses the target.

The address 64 is the head address of the memory area of the access target in the external memory device represented by the device name 63, and the like.

The number of data 65 is, for example, a memory area representing the above access target Capacity, etc. For example, if the address 64 is the "address field 101" and the data number 65 is "3", the address field 101 to the address field 103 are the memory areas of the access target.

The memory area represented by the address 64 or the like of the memory device represented by the device name 63 in the connected device represented by the memory mode 61 is equivalent to the allocated memory area. The object of the change made by this method is mainly the area of the allocated memory.

Next, a specific example of the memory address settable range data 24 will be described below with reference to FIGS. 6(a), (b) and FIG.

Fig. 6(a) shows an example of a data structure of the entire memory address settable range data 24.

Here, according to the above, when there are a plurality of connected devices 4 connected to the programmable display 1, the memory address settable range data 24 is also stored in a plurality of types. That is, the memory address settable range data 24 corresponding to each connected device 4 is stored.

Further, each of the memory address settable range data 24 is provided with each settable range information 70 corresponding to each of the memory devices of the connected device 4. In other words, when there are a plurality of external memory devices in the corresponding connected device 4, a plurality of settable range information 70 is provided as shown in the figure. Further, in Fig. 6(a), a case where the range address data 24 of the memory address is connected to any connected device 4 (this is assumed to be the connected device A) is made. Show.

Here, the connection device A is assumed to have three memory devices D, W, and M. Therefore, the memory address settable range data 24 associated with the connected device A is set as the three settable range information 70 corresponding to the three memory D, W, and M of the three devices. to make.

Here, it is assumed that the device No. is assigned to each of the settable range information 70. The device No. is, for example, generally assigned a sequence number as in 0, 1, 2, 3, ..., etc. Therefore, in the example shown in the figure, the device No. "0" is assigned to the first settable range information 70, and the device No. "1" is assigned to the second settable range information 70. In the third settable range information 70, the device No. "2" is assigned.

In addition, the device No. is used, for example, when displaying a list of the device selection fields 102 on the memory address change dialog 100 shown in FIG. 13(a) to be described later. The details will be described later.

Further, for example, the other connected device 4 (assumed to be the connected device B) can be configured to have the device No. "0", the device No. "1", and the like, similar to the above-described connected device A. Of course, in the case of this example, at the connection device A and the connection device B, the names of the memory devices corresponding to the respective device Nos are different (although there may be cases where they are accidentally the same). For example, the device No. “0” connected to the device A is the memory device D as described above. The device No. "0" to which the device B is connected is, for example, a memory device C or the like.

In other words, the device No. can be commonly used in all connected devices, but the content (the corresponding memory device) is associated with each of the connected devices.

In Fig. 6(b), a specific example of the settable range information 70 is shown.

In the example shown in FIG. 6(b), the range information 70 can be set, including the device name 71, the memory unit 72, the numerical form 73, the minimum address 74, the maximum address 75, and the like. Further, although not shown, the above device No. may be further present.

The device name 71 is identification information of the above external memory device.

The memory unit 72 is slightly the same as the above-described memory access 62, and is an access form for the external memory device represented by the device name 71 (1 bit access, 16 bit access, etc.). .

The numerical form 73 is a data representing the form in which the value of the address of the external memory device represented by the device name 71 should be expressed and increased (for example, DEC (10-bit), HEX (16-bit). , OCT (8-bit), etc.).

The minimum address 74 and the maximum address 75 are displayed for the settable address range of the external memory device represented by the device name 71. For example, if the minimum address 74 = "0" and the maximum address 75 = "65535", the address range can be set to 0 to 65535. in In this method, the address outside the address range can be set to be substantially unprocessable (even if the user makes a setting, it will become an error, or it will not be prompted as a selection condition, etc.) Therefore, it is possible to prevent setting errors from occurring.

In FIG. 7, as a hypothetical example, a specific example of the settable range information 70 is shown for each of the three types of external memory devices of the device D, the device W, and the device M connected to the device A. .

Hereinafter, setting information (memory mode 61, device name 63, and address 64) for allowing the user to arbitrarily set the allocation memory address associated with any item on the side of the programmable display 1 The above is a description of a specific example of the process of changing the address setting error. Here, the following two embodiments (Example 1, Example 2) are described, but are not limited to these examples.

In the following, in the first embodiment, the user can freely perform the resetting of the address or the like. However, it is configured to check the presence or absence of the setting error, and when there is a setting error. The address is not changed (constituted so that the content input by the user is not reflected in the device name 63 or the address 64 or the like).

Further, in the second embodiment below, although the user can select and input the address or the like, the address in the settable address range can be selected only, and the addressable range cannot be selected. The composition of the address other than the address. Also, regarding this matter, it is not limited to the position. The re-setting of the connection device name (memory mode 61) or the external memory device name (device name 63) is also the same. That is to say, regarding the connection of the machine name, only the correct option is indicated (so that no setting error occurs regardless of which one is selected). Similarly, regarding the name of the external memory device, only the correct option is indicated (so no setting error occurs regardless of which one is selected).

Hereinafter, the first embodiment will be described with reference to FIGS. 8, 9, and 10.

8 and 9 are flowcharts (1/2) and (2/2) of the address change processing of the first embodiment. In addition, the following is not particularly distinguished, and is described as FIG. 8 and the like.

If the user performs a predetermined operation, the address change processing shown in FIG. 8 and the like is started. In the example shown in the figure, the user performs a "long press" operation on an arbitrary item determined to be the address change target, but is not limited to this example.

In the processing example shown in FIG. 8 and the like, the programmable display 1 performs a "long press" operation on the item of the desired address change target (step S11, YES), for example, FIG. 10 (FIG. 10) The memory address change window 90 shown in a) is displayed (step S12). In the memory address change window 90, a display column 91, an input unit 92, a "change" key 93, and the like are displayed. At the input unit 92, for example, a numeric key or an alphanumeric input key or the like is displayed, and the user can input a desired Arabic numeral or numerical value. The user, at the input unit 92, performs the desired memory mode and the desired external memory. Input operation of the device, the name of the desired address/identification information or numerical value, etc. This input content is displayed at the display column 91.

Further, in the present example, the external memory device is assumed to be an input name (memory device name), but is not limited to this example, and may be identification information (ID or the like).

Further, the present invention is not limited to this example, and for example, a configuration in which the user can perform only an input operation (change) of a desired address can be employed. In other words, it is also possible to adopt a configuration in which the setting of the memory mode (connected device) or the external memory device cannot be changed. Further, in the case of this example, the memory mode 61 or the device name 63 may be read and displayed (displayed only, and cannot be changed).

Alternatively, it may be configured such that the memory mode (connected device) cannot be changed.

The user confirms the display content of the display field 91, and if it is OK, the "change" key 93 is operated.

By this, the following processing corresponding to this operation is performed (step S13).

First, based on the memory mode (the designation of the desired connected device 4) input by the user, the communication I/F driver 25 corresponding to the connected device 4 is determined (the memory address of which can be set) Scope information 24). For example, when the connection device A is designated, the communication I/F driver 25a (the memory address settable range data 24a) for the connected device A shown in the figure is discriminated.

After that, the memory address can be set using the determined memory address. The range data 24 is used to check whether the memory device name or address input by the user is normal. Further, when there is no memory address settable range data 24 corresponding to the memory mode input by the user, the "input error" may be notified (for example, the setting of the connection device is notified).

The above-described inspection processing, for example, first acquires the settable range information 70 corresponding to the name of the memory device input by the user. In this regard, for example, the acquired device name 71 is the settable range information 70 that matches the memory device name input by the user. However, when there is no case in which the settable range information 70 is satisfied, for example, it may be configured to notify the error information such as "the input of the memory device name is incorrect".

Further, when only the form of the address can be input, the memory mode or the memory device name input by the user is used, and the memory mode 61 associated with the item of the address change target is used or Device name 63.

Thereafter, it is checked whether the address input by the user is within the settable address range displayed by the minimum address 74 and the maximum address 75 of the settable range information 70 obtained as described above (step S14).

When the user inputs the address to be within the range of the settable address, it is determined to be normal (step S14, YES), and the process proceeds to step S15. On the other hand, when the user inputs the address to be outside the range of the settable address, it is determined to be abnormal (step S14, NO), and the process proceeds to step S16.

In step S15, the screen material 22 is updated by the user inputting the material. In other words, the information related to the item of the address change object (memory mode 61, device name 63, address 64, etc.) in the screen data 22 is the memory mode input by the user. Rewrite (overwrite, update) the memory device name and address. Of course, in the case where the above-described form can only be changed to the address, only the address 64 is changed by the address input by the user.

On the other hand, in the step S16, the above-described processing of the step S15 is not performed, and for example, the general error display shown in Fig. 10 (b) is performed.

If the processing of any of the above steps S15 and S16 is performed, the processing ends.

Further, in the initial screen of the memory address change window 90, the current (pre-change) setting address content may be displayed in the display field 91. In this case, the data (device name 63, address 64, etc.) of the address change target item is obtained from the screen data 22 and displayed. The user, after confirming the display content, determines whether the desired address or the like is to be input when it is determined that the change is necessary.

Next, the second embodiment will be described with reference to FIGS. 11, 12, and 13.

11 and 12 show the flow of the address change processing of the second embodiment. Figures (1/2), (2/2). In addition, the following is not particularly distinguished, and is described as FIG. 11 and the like.

If the user performs a predetermined operation, the address change processing shown in FIG. 11 and the like is started. The predetermined processing is a "long press" operation performed by the user on the item of the address change object in the illustrated example.

In other words, in the processing example of FIG. 11 and the like, if the user performs a "long press" operation on the item of the desired address change (step S21, YES), for example, in FIG. 13(a) The memory address change dialog 100 shown is displayed (step S22).

In the illustrated example, in the memory address change dialog 100, for example, for each of the connected devices, devices, and addresses, the user is prompted to select candidates, and the user selects from among the options. The candidate of choice is expected.

In this regard, first, in the connected device selection field 101, the names/IDs of all the connected devices 4 that are being connected to the programmable display 1 are displayed in a list (this is a name). In the example shown in the figure, the connected device names "PLC1", "PLC2", and "PLC3" are displayed in the list. In addition, such connected device names exist, for example, in each memory address settable range data 24.

On the other hand, if the user selects the desired connected device, the memory address settable range data 24 corresponding to the selected connected device is obtained. Therefore, based on the obtained address settable data 24, the external memory device and the address are sequentially displayed. The candidate is added (step S23). That is, first, the device name 71 of all the settable range information 70 of the acquired address settable range data 24 is displayed in a list in the device selection column 102 shown. Thereafter, if the user selects the desired external memory device in the device selection field 102, the settable range information 70 corresponding to the selected external memory device is obtained.

Therefore, based on the obtained minimum address 74 and the maximum address 75 of the settable range information 70, only the address within the settable address range is displayed as an option in the address selection of the icon. At column 103. In addition, it is also possible to use the data of the numerical form 73 or the like in order to perform this display.

The user operates in the address selection field 103 to display a desired address value in response to the up/down key or the like, and then operates the "change" key 104 shown in the figure (step S24). .

Thereby, the screen material 22 is updated in response to the user selection result in the connected device selection field 101, the device selection field 102, and the address selection field 103. In other words, the information (memory mode 61, device name 63, address 64, etc.) of the item to be changed in the screen data 22 is connected to the device selected by the user, The external memory device, the address, and the like are rewritten (overwritten, updated) (step S26).

However, it may be configured to allow the user to input an arbitrary address or the like, and perform the steps of the above-described Embodiment 1 in response to this example. Step S14 is slightly the same as the normal check (step S25). Of course, when it is determined that the abnormality is present (step S25, NO), the processing of the above step S26 is not performed. Instead of this, for example, processing such as displaying an error display screen shown in FIG. 13(b) is performed (step S27). However, the processing of steps S25 and S27 is not absolutely necessary.

In addition, in the second embodiment, the same applies to the above-described example, and for example, it may be configured such that the address can be changed only. In the case of this form, the settable range information 70 corresponding to the memory mode 61 and the device name 63 associated with the item to be changed in the address is obtained. Thereafter, only the address within the settable address range obtained based on the obtained minimum address 74 and the maximum address 75 of the settable range information 70 is available in the address selection field 103. Make a choice. Further, in the case of this aspect, for example, instead of the connection device selection field 101 and the device selection field 102, the memory mode 61 and the device name 63 which are related to the address change target may be provided. Display bar (not shown).

Here, a description will be given of a process using the device No. when the list of the device selection fields 102 on the memory address change dialog 100 shown in FIG. 13(a) described above is displayed.

The device selection field 102 is, for example, a combo box. For example, when the device A is connected as described above, the three memory device names D, W, and M are displayed in a list and selected. At this time, the display order, for example, may exist as a graph The general display order shown in Figure 14. In the determination of the display order, the above device No. is used. For example, it is displayed in order from the device No. to the small one. In the case of this example, in the example of Fig. 6(a) described above, each memory device is displayed in the order of "D" -> "W" -> "M" as shown in Fig. 13 (a). name.

For example, when the developer or the like wants to display in the desired order, the device No. of the memory address settable range data 24 is arbitrarily set. In addition, if the device No. is not used, it is necessary to additionally set a table in which each memory device name and display order are associated with each other. Of course, if any display order is available, such a table or the like or a device No. is not essential.

As described above, in the programmable display 1 or the like of the present example, the user is able to set information on the allocated memory address of any item related to the operation display screen at the programmable display 1 (memory address information 55). Etc.) Make changes. Therefore, compared with the prior art, the burden of the change operation can be reduced. Further, at this time, it is possible to prevent the occurrence of a setting error such as an address. Moreover, the amount of data required for the setting error prevention processing can be greatly reduced (or the processing can be performed by the programmable display 1). It is possible to surely transmit only the data necessary for the setting error prevention processing for each of the programmable displays 1 from the drawing editing device 5 (because the communication necessary for the programmable display 1 is required) The program is sent in pairs to the ground).

According to the above-described programmable display 1 or the like, it is configured such that the screen data (the allocated memory address, etc.) that has been stored on the programmable display 1 side can be corrected and changed on the programmable display 1 side. The system can reduce the burden of correction and change operations. Further, it is possible to prevent the occurrence of a setting error at this time.
