Abstract

PURPOSE:To simplify the updating job of a module by using a DLL task which replaces the module of its own system with a module received from a basic processor and at the same time updates the revision of a work station WS module control table. CONSTITUTION:A DLL task 6 set at a WS 4 informs a basic processor 1 of the contents of its own WS module control table 5 at rise of the WS 4. A DLL task 3 of the processor 1 compares the contents of its own WS module control table 2 with the contents of the table 5 received from the WS 4 and sends only the modules having different revisions to the WS 4. Then the task 6 of the WS 4 replaces the module received from the processor 1 with a module of its won system and at the same time updates the revision of the table 5. Thus a module can be easily updated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a workstation module update method.

[Conventional technology]

In a system in which a plurality of workstations are connected to a basic processing unit, it becomes necessary to update software modules in order to expand the functions of the system.

Conventionally, there has been no method for updating modules in such cases in which the entire system is processed at once, and modules have been updated separately in the basic processing unit and each workstation. That is, on the basic processing device side, modules are updated based on the functions provided by the operating system of the basic processing device, and on the workstation side, modules are updated based on the functions provided in the operating system of the workstation.

[Problem to be solved by the invention]

Conventional module updating was performed as described above, which had the following drawbacks.

■If there are many workstations in the same system, the same module update work must be done for each one, making the work complicated and inefficient.

■If the basic processing unit and workstation have different operating systems, extensive knowledge of both operating systems is required, and not everyone can easily update the module.

The present invention has been proposed in view of the above points, and its purpose is to automatically update the modules of all workstations that make up the system by simply updating the modules on the basic processing unit side. The object of the present invention is to provide a workstation module update method that allows easy module update.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a software module update method in a system in which a plurality of workstations are connected to a basic processing unit. The WS module management table associated with the vision is compared with the contents of its own WS module management table, which is provided in the basic processing unit and is notified of the contents of the WS module management table from the workstation, to determine the revision. a DLL task that sends only different modules to the current workstation; a DLL task provided in the workstation that notifies the basic processing unit of the contents of its own WS module management table when the workstation starts up; It is provided with a DLL task that replaces the module of its own system with the module sent from the basic processing unit and updates the WS module management table and vision.

[Operation] In the workstation module update method of the present invention, the DLL task provided in the workstation sends its own WS module management table to the basic processing unit when the current work stage 5 starts up. When the DLL task provided in the basic processing unit is notified of the contents of the WS module management table from the workstation, it compares it with the contents of its own WS module management table and selects only the modules with different revisions. Send to the Pig workstation. Then, the DLL task provided in the workstation replaces the module in its own system with the module sent from the basic processing unit, and also updates the WS module management table Norivision.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a system using the workstation module update method of the present invention. In FIG. 1, a basic processing device 1 is the core of the system, and a plurality of workstations 4 are connected to this basic processing device 1 via communication lines 7.

On the other hand, as a configuration related to the present invention, the basic processing device 1 has a WS module management table 2 that associates module names and visions (revised) registered in the basic processing device 1 at the present time, and a download line load DLL that performs
Task 3 is provided. In addition, the workstation 4 has a WS module management table 5 that associates the module names and visions currently registered in the work stage 5, and a WS module management table 5 that is associated with the module names and visions currently registered in the work stage 5.
LL task 6 is provided. Examples of the WS module management table 2.5 are shown in FIGS. 2 and 3, and the functions of the DLL task 3.6 are as follows.

DLL task 3: When notified of the contents of the WS module management table 5 from the workstation 4, the own W
Compare the contents of the S module management table 2 and select only modules with different revisions from the workstation 4.
Function to send to.

DLL task 6: When starting up the own workstation 4, notifies the basic processing unit 1 of the contents of its own WS module management table 5, and replaces the module of the own system with the module sent from the basic processing unit 1. This function also updates the revision of the WS module management table 5.

The operation of the above embodiment will be explained below.

First, the W of basic processing unit 1 and workstation 4
Assume that the contents of the S module management table 2.5 are in the state shown in FIG.

If it becomes necessary to update module B in this state, module B is updated in basic processing device 1 according to its operating system. At the same time as the update, the revision for module B in the WS module management table 2 is also updated from b to b', resulting in a state as shown in FIG.

On the other hand, on the workstation 4 side, as shown in the flowchart of FIG. The content is notified to the basic processing device 1 via the communication line 7 (step S2
).

Upon receiving this notification, the basic processing device 1 side compares the contents of its own WS module management table 2 with the contents of the WS module management table 5 of the notified workstation 4 (step 33), and compares the contents of the WS module management table 5 of the notified workstation 4. Latest content, i.e. Figures 2 and 3
In the illustrated example, the updated contents of module B are sent to the workstation 4 via the communication line 7 (step S4).

On the workstation 4 side, the sent module B is used to replace module B in its own system, and the module is updated (step S5).Furthermore, the workstation 4 side updates the module B in its own WS module management table 5. is also updated from b to b゛ as shown in Figure 3 (
Step S6).

Similar processing is performed for the other workstations, and the modules of each workstation are updated to the same state as the modules registered in the basic processing device f when each workstation is started up.

〔Effect of the invention〕

As explained above, in the workstation module update method of the present invention, once the module is updated on the basic processing unit side, the changed module will be updated when the workstage is started up. ■The task of updating modules does not become complicated even when there are many workstations.

■Module updates can be done with just knowledge of the operating system on the basic processing unit side.

There are other effects.
