Description

description

Modular signaling device The invention relates to a modular signaling device. Signaling devices are used in particular in the field of automation technology, in particular industrial automation technology. In particular, a signaling device is a button (e.g., a on button) or switch (e.g., an on / off switch, a rotary switch, an emergency stop switch). By actuating the signaling device, at least one state change is brought about at the signaling device, which can be detected, for example, by an appliance unit which is electrically connected to the signaling device, so that it can react accordingly. Signaling devices are used within the automation technology, for example, in a control panel of a production line, so that a user can output appropriate signals by pressing individual annunciators of the control panel.

A known signaling device, for example, an emergency stop

Switch. The emergency stop switch, also called emergency stop, is usually a switch which is intended to put a machine or a system in case of danger or to avert a danger quickly to a safe state when operating the switch. Depending on the field of application, different strategies are pursued here. In the simplest case, an actuation of the emergency stop switch follows an interruption of the power supply of the plant or machine causing the danger. For this purpose, usually the control circuit of a contactor, via which the energy supply of the risk causing machine is guided, passed through the signaling device. If the signaling device is actuated, it interrupts the control circuit of the contactor, so that the contactor opens its contacts and the power supply to the machine is prevented. Signaling devices usually comprise at least three components. An actuator, a recording module and a basic detection module. In particular, the actuator comprises a feeler element or a switching element for the direct actuation of a user. In the assembled state of the signaling device, the actuator and the base detection module are mechanically connected to the receiving module.

Actuation of the actuator usually deflects a plunger of the signaling device. About the deflection of the

Tappet is usually applied directly a mechanical force on a mechanical contact element of the basic detection module, so that this brings about a change of state (the contact element is opened or closed). By monitoring the switching position of the contact element of the base detection module, e.g. by a decentralized device unit, a conclusion can be obtained on the present switching state of the signaling device. If, for example, the signaling device comprises two independent sensing elements or a switching element which allows two or three different switching positions, then usually per sensing element or ever

Switching position of the switching element, a separate plunger on the signaling device deflected. Each of these plungers is associated with a separate contact element, which changes its switching position at a deflection of the plunger. By monitoring the respective switching positions of the contact element, a conclusion can therefore be drawn on the present state of the actuator of the signaling device. If the base detection module comprises only one movable plunger, the signaling device can usually be extended by means of a separate extension detection module comprising a plunger. For this purpose, the separate expansion detection module is first mechanically connected to the recording module of the signaling device. A deflection of the plunger of the extension detection module causes a switch position of the switch not monitored by the base detection module Detected switching element or an actuation of the not monitored by the base detection module probe element. For this purpose, the expansion detection module also comprises a mechanical contact element, which has a specific switching position as a function of the position of the plunger of the expansion detection module (contact element is open or closed). Depending on the present switching position of the contact element of the expansion detection module, a conclusion can be drawn on the present switching position of the switching element or an actuation of the not detected by the base detection module probe element. In order to determine the present switching state of the signaling device, the contact element of the base detection module and the contact element of the extension detection module are usually evaluated separately.

An object of the present invention is to provide an improved signaling device. In particular, a signaling device is to be provided, which can be adapted extremely flexibly with regard to a used actuator.

This object is achieved by a device according to claim 1, i. by a modular signaling device having a base detection module, which comprises a first sensor for contactless detection of a first position of a movably mounted first plunger of the signaling device.

Advantageous developments of the invention are specified in the dependent claims 2 to 12.

The signaling device (eg a pushbutton, a rotary switch, a key switch, an emergency stop switch) comprises, in addition to the basic acquisition module, a receiving module and an actuator. In the assembled state of the signaling device, the actuator and the base detection module are mechanically non-destructively releasably connected to the receiving module. Preferably, the receiving module may further comprise a first and / or second extension detection module mechanically non-destructively releasable to take. The connection of the individual detection modules with the receiving module is preferably carried out in each case by means of a snap connection. The receiving module is in particular designed such that it can accommodate different actuators. The actuator is the assembly of the signaling device, via which a user can cause a change in state of the signaling device. The actuator comprises, for example, a probe element or a switching element. By means of the probe element is for the

Period of its operation brought about a change of state at the annunciator. In the switching element, the state of the signaling device can be determined by selecting the available switching positions of the switching element. Actuation of the actuator preferably deflects the first plunger of the signaling device.

The first plunger of the signaling device is movably mounted in the signaling device, in particular in the basic detection module or in the first expansion detection module of the signaling device.

On the first plunger of the signaling device is preferably a force, in particular spring force exerted, which moves the first plunger in the uncoupled state with the receiving module of the signaling device in a basic position which does not correspond to the first position of the plunger. In the uncoupled state with the receiving module is thus not the first position of the first plunger before. The first position is preferably present when the base detection module or the first extension detection module is properly connected to the recording module, which is connected to an actuator, or if additionally the actuator has been actuated, ie the probe element has been actuated or a defined switching position of the switching element is located in front . By means of the first sensor, the state of the first plunger, in which the first plunger is in the first position, can be detected in a targeted manner. The detection of the first position of the first plunger by means of the first sensor is preferably carried out in inductive, capacitive, optical or magnetic manner.

The first sensor is preferably arranged on a printed circuit board of the base detection module. Preferably, during the deflection of the first plunger, the first plunger is moved substantially parallel to the circuit board.

If the first ram is movably mounted in the base detection module, the first ram preferably protrudes with the receiving module out of the base detection module in the uncoupled state of the base detection module and is in the basic position. By mechanically connecting the base detection module to the receiving module, the first plunger is deflected to its first position. Because the first sensor can detect the state of the first plunger in its first position in a targeted manner, it can be monitored by means of the first sensor whether the basic detection module is properly connected to the recording module of the signaling device. However, it is also conceivable that the first position of the first plunger is present only when an actuation of the actuator. Consequently, the base detection module would detect actuation of the actuator by means of the first sensor. Characterized in that the first position of the first plunger of the signaling device is detected without contact by means of the first sensor, there is a very low-wear ram monitoring. Furthermore, a flexible tappet guide is made possible within the signaling device. For example, despite central determination of the position of the first plunger within the basic detection module, the first plunger may be guided outside the basic detection module. As a result, a highly flexible design of the signaling device is made possible. In an advantageous embodiment of the invention, the signaling device comprises a first extension detection module, which is arranged next to the base detection module and which comprises the first movably mounted tappet, wherein the base detection module can detect the first position of the first tappet contactlessly with the first sensor.

In particular, the first extension detection module is arranged directly opposite a first side surface of the base detection module.

The first plunger of the first expansion sensing module is movably supported in the first expansion sensing module. By means of the first sensor of the basic detection module, the state of the first plunger in which the first plunger is in the first position can be detected in a targeted manner.

A deflection of the first plunger of the first expansion detection module into the first position is brought about in particular by the mechanical connection of the first expansion detection module to the reception module, which is mechanically connected to the actuator, or to an additional actuation of the actuator of the signaling device. In this case, the first plunger is in particular moved into the device interior of the first expansion detection module. The base detection module can detect a deflection of the first plunger in the first position by means of its first sensor, so that a conclusion about the state of the signaling device can be obtained.

The signaling device can thus be used as needed, i. if e.g. two sensing elements are installed on the actuator or when the actuator is a switching element with two to be detected

Switch positions comprises, can be extended easily. The detection of the state of the actuator on the position of the first plunger is done centrally by the base detection module. In this way, a small number of variants with respect to the modules of the signaling device can be achieved because the When using two sensing elements or a switching element with two switch positions to be monitored signaling device only with a first extension detection module must be extended. It can thus be extremely flexible response to the actuator used.

Furthermore, since the expansion sensing module only needs to be coupled to the capture module, ease of assembly and construction is achieved.

In an advantageous embodiment of the invention, the first plunger protrudes in the uncoupled state of the first expansion detection module with the receiving module from the first expansion detection module and has its basic position on.

In a further advantageous embodiment of the invention, the first position of the first plunger is present when the first expansion detection module is mechanically connected to the receiving module of the signaling device, which is mechanically mechanically connected to the actuator of the signaling device properly.

By properly mechanically connecting the first expansion sensing module to the capture module, inclusive

Actuator takes the first plunger, the first position, which does not correspond to the basic position of the first plunger in the uncoupled state of the first expansion detection module with the recording module. By mechanically connecting the first expansion sensing module to the receiving module, the first plunger is thus deflected to its first position. By means of the first sensor, the base detection module can specifically detect the state of the first plunger, in which the first plunger is in the first position. Preferably, the signaling device outputs a characteristic signal via a communication unit if it detects the first position of the first plunger by means of the first sensor. If the actuator of the signaling device is actuated, the first plunger preferably assumes a second position by actuation of the actuator which does not correspond to the basic position and the first position of the first plunger. The second position of the first plunger may preferably be detected by means of a fourth sensor of the basic detection module.

By means of the first sensor, the base detection module can contactlessly detect whether the first plunger has the first position or not. If the first position is detected, then there is a properly coupled first expansion detection module with the recording module. In an advantageous embodiment of the invention, the base detection module comprises a fourth sensor, which is preferably arranged on the circuit board of the base detection module. By means of the fourth sensor, the base detection module can selectively detect the first plunger in its second position.

If the first extension detection module is not connected to the receiving module or incorrectly connected (the basic position of the first plunger is present), the presence of the first plunger in the first position and the fourth sensor by the first sensor in the second position not detected.

If the first expansion sensing module is properly connected to the acquisition module, the first ram has the first position. The first sensor thus detects the presence of the first plunger in its first position. By means of the fourth sensor it is detected that the first plunger does not have the second position.

If the first expansion sensing module is properly connected to the capture module and the actuator has been actuated (ie the actuator is not in its home position), then is detected by the first sensor that the first plunger does not have the first position. However, the fourth sensor determines that the first plunger has the second position.

Consequently, the base detection module can always detect the above states by means of the first and fourth sensors and output corresponding signals via its communication unit. It is also conceivable that the signaling device does not comprise an expansion detection module, so that the movably mounted first plunger is the plunger of the base detection module and the base detection module can detect the first position of the first plunger of the base detection module without contact by means of the first sensor.

In a further advantageous embodiment of the invention, the base detection module comprises a movably mounted second plunger and a second sensor, wherein the base detection module can detect with the second sensor contactlessly the first position of the second plunger.

If the signaling device includes a first expansion detection module, then at least two sensors are arranged in the base detection module and two plungers are present in the signaling device.

The first sensor is for detecting the first position of the first plunger of the first expansion detection module, and the second sensor is for detecting the first position of the second plunger of the basic detection module.

The second plunger is movably mounted in the base detection module. Preferably, the second plunger protrudes in the uncoupled state with the receiving module from the base detection module and has its basic position.

A deflection of the second plunger of the basic detection module in the first position is in particular by the mechanical Connecting the base detection module with the receiving module, which is mechanically connected to the actuator, or brought about an actuation of the actuator of the signaling device. In this case, the second plunger is moved in particular into the device interior of the basic detection module. By means of the second sensor, the base detection module can specifically detect the state of the second plunger, in which the second plunger is in the first position. Preferably, the signaling device outputs a characteristic signal via a communication unit if it detects the first position of the second plunger by means of the second sensor.

During the deflection of the second plunger, the second plunger is preferably moved substantially parallel to the surface of the circuit board of the base detection module.

The second sensor is preferably arranged on the circuit board of the base detection module. In an advantageous embodiment of the invention, the first position of the second plunger is present when the basic detection module is mechanically connected to a receiving module of the signaling device, which is mechanically connected mechanically properly with an actuator of the signaling device.

By virtue of the proper mechanical connection of the base detection module to the receiving module, the second plunger assumes the first position, which does not correspond to the basic position of the second plunger in the uncoupled state of the basic detection module with the receiving module.

If the actuator of the signaling device is actuated, the second plunger preferably assumes a second position by actuation of the actuator which does not correspond to the basic position and the first position of the second plunger. This position can preferably be detected by means of a fifth sensor of the basic detection module. By means of the second sensor, the base detection module can detect without contact whether the second plunger has the first position or not. For this purpose, the second sensor can purposefully detect the second plunger in its first position. If the first position of the second plunger is detected, then a properly coupled basic detection module with the receiving module is present.

In an advantageous embodiment of the invention, the base detection module comprises the fifth sensor, which is preferably arranged on the circuit board of the base detection module. By means of the fifth sensor, the base detection module can selectively detect the second plunger in its second position.

If the basic detection module is not connected to the receiving module or is incorrectly connected, the second sensor does not detect the presence of the second tappet in the first position and the fifth sensor does not detect the presence of the second tappet in the second position. The basic position of the second plunger is thus recognized by the fact that the second sensor and the fifth sensor do not detect a second plunger. If the base detection module is properly connected to the receiving module, the second ram has the first position. The second sensor thus detects the presence of the second plunger in its first position. By means of the fifth sensor it is recognized that the second plunger does not have the second position.

If the base detection module is properly connected to the pickup module and the actuator has been actuated (ie, the actuator is not in the home position), the second sensor detects that the second pusher is not in the first position. However, it is determined by the fifth sensor that the second plunger has the second position. Consequently, the base detection module can always detect the above states by means of the second and fifth sensors and output corresponding signals via its communication unit. In a further advantageous embodiment of the invention, the modular signaling device comprises a second expansion detection module arranged in parallel with the base detection module, wherein the second extension detection module comprises a third movably mounted plunger, wherein the base detection module can detect a first position of the third plunger contactlessly with a third sensor.

The second extension detection module is designed separately from the base detection module and is designed in a manner that is identical in construction to the first extension detection module.

The first extension detection module preferably lies directly opposite a first side surface of the base detection module. Specifically, the second extension detection module directly faces a second side surface of the base detection module opposite to the first side surface of the base detection module.

The sibling second expansion detection module is mechanically connectable in particular by means of a connecting means with the receiving module. The mechanical connection of the second extension detection module with the receiving module is in particular a nondestructive releasable connection, in particular a snap connection.

The third plunger of the second expansion sensing module is movably supported in the second expansion sensing module. In the uncoupled state of the second expansion detection module, the third plunger preferably projects out of the second expansion detection module with the reception module. A deflection of the third plunger of the second expansion detection module into the first position is brought about in particular by the coupling of the second expansion detection module to the reception module, which is mechanically connected to the actuator or to an actuation of the actuator of the signaling device. In this case, the third plunger is in particular moved into the device interior of the second extension detection module. By means of the third sensor, the state of the third plunger can be detected in a targeted manner, in which the first plunger is in the first position.

The third sensor is preferably arranged on a printed circuit board of the base detection module.

Preferably, during the deflection of the third plunger, the third plunger is moved substantially parallel to the lyre plate of the base detection module.

In a further advantageous embodiment of the invention, the first position of the third plunger is present when the second expansion sensing module is properly mechanically connected to a receiving module of the signaling device, which is mechanically mechanically connected to an actuator of the signaling device.

By properly mechanically connecting the second expansion sensing module to the receiving module, the third ram assumes the first position that does not correspond to the base position of the third ram in the uncoupled state of the second expansion sensing module with the receiving module. If the actuator of the signaling device is actuated, the third plunger preferably assumes a second position by actuation of the actuator, which does not correspond to the basic position and the first position of the third plunger. The second position of the third plunger can preferably be detected by means of a sixth sensor of the basic detection module. By means of the third sensor, the base detection module can detect without contact, whether the third plunger has the first position or not. If the first position of the third plunger is detected, then there is a properly coupled second expansion detection module with the receiving module. The basic position of the third plunger is preferably recognized by the fact that the third sensor and, if present, the sixth sensor does not detect a third plunger.

In an advantageous embodiment of the invention, the base detection module comprises a sixth sensor, which is preferably arranged on the circuit board of the base detection module. By means of the sixth sensor, the base detection module can selectively detect the third plunger in its second position.

If the second extension detection module is not connected to the receiving module or is incorrectly connected, then the third sensor does not detect the presence of the third tappet in the first position and the sixth sensor does not detect the presence of the third tappet in the second position.

If the second expansion sensing module is properly connected to the capture module, the third trigger has the first position. The third sensor thus detects the presence of the third plunger in its first position. By means of the sixth sensor it is detected that the third plunger does not have the second position.

If the second expansion module is properly connected to the pick-up module and the actuator has been actuated (ie the actuator is not in the home position), the third sensor detects that the third plunger is not in the first position. By the sixth Sensor is determined, however, that the third plunger has the second position.

Consequently, the base detection module can always detect the above states by means of the third and sixth sensors and output corresponding signals via its communication unit.

The detection of the first and / or second position of the first, second and / or third plunger by means of the associated sensor of the basic detection module is preferably carried out in inductive, capacitive, optical or magnetic manner.

In a further advantageous embodiment of the invention, the first, second, third, fourth, fifth and / or sixth sensor of the basic detection module is in each case a Hall sensor. The plunger to be monitored in each case comprises a magnet, which can be detected by means of the Hall sensor in the presence of the associated position of the plunger. The magnet of the respective plunger is arranged in particular in the interior of the basic detection module or extension detection module, in particular at the end of the plunger. The first and / or second position of the plunger to be monitored can be detected by means of the corresponding Hall sensor of the basic detection module. For this purpose, in particular the magnet on the plunger and the respective Hall sensor in the base detection module are arranged such that in the presence of the corresponding plunger position means of the Hall sensor, a characteristic magnetic field of the magnet of the plunger is detected.

In the basic position of the plungers, the associated Hall sensors do not detect a characteristic magnetic field.

In the first position of the plungers, the first, second and third Hall sensors detect the characteristic magnetic field and the fourth, fifth and sixth plungers do not detect any characteristic magnetic field. In the second position of the plunger, the first, second and third Hall sensors do not detect a characteristic magnetic field and the fourth, fifth and sixth plungers detect the characteristic magnetic field.

In a further advantageous embodiment of the invention, the base detection module comprises a communication unit, by means of which the base detection module can be connected to a bus for communication and device-internal power supply.

The base acquisition module can receive the device-internal power supply via the bus of the signaling system connected to the communication unit. By means of the energy obtained via the communication unit, in particular the energy supply of the first, second, third, fourth, fifth and / or sixth sensor takes place.

In particular, the communication of the basic detection module with a decentralized one takes place via the communication unit

Central module of the reporting system. If the first and / or second position of the respective plunger is detected by the base detection module by means of its sensors, the base detection module outputs a corresponding characteristic signal via the communication unit. On the basis of the characteristic signals, a central module can detect the present state of the signaling device (for example base detection module and / or extension detection module / s are properly connected to the recording module including actuator, present switching state of the signaling device).

The central module preferably comprises not only a communication unit for communication within the reporting system, but also a further communication unit by means of which the central module can communicate with a higher-level bus system. The higher-level bus system is, for example, a Profibus, AS-Interface or IO-Link communication system. The central module is preferably formed by a base detection module of a detector device of the reporting system.

In a further advantageous embodiment of the invention, the modular signaling device comprises a receiving module, which is mechanically connected to an actuator, wherein the base detection module is mechanically connected to the receiving module, wherein upon actuation of the actuator at least one of the plunger is deflected to a second position and the Base detection module can detect by means of its sensor, the deflection of the plunger in the second position.

At least one of the plungers of the base detection module is deflected upon actuation of the actuator in the second position. If the base detection module detects a deflection of the corresponding plunger into the second position, it preferably emits a characteristic signal via its communication unit. If a first expansion detection module is present, the first plunger of the first expansion detection module is deflected in an actuation of the actuator in the second position. If the base detection module detects a deflection of the second plunger to the second position, it preferably emits a characteristic signal via its communication unit.

If a second expansion detection module is present, the third plunger of the second expansion detection module is deflected in an actuation of the actuator in the second position. If the base detection module detects a deflection of the third plunger into the second position, it preferably emits a characteristic signal via its communication unit.

The actuator is preferably designed such that the first, second or third plunger can be selectively deflected into the second position by it. The actuator can for example, comprise three sensing elements, is deflected by an actuation of the first sensing element of the first plunger in the second position, is deflected upon actuation of the second probe element, the second plunger in the second position and upon actuation of the third probe element of the third plunger in the second position is deflected. It is also conceivable that the actuator comprises a switching element which moves in a first switching position only the first plunger in the second position, in a second switching position only the second plunger moves to the second position and in a third switching position, only the third plunger in moves the second position. In a further advantageous embodiment of the invention, the base detection module comprises a light source (eg an LED), via which an illumination of the actuator of the signaling device can take place. If a transparent actuator is present, a lit actuator is present during active operation of the light source. Preferably, the energy for the light source is obtained via the communication unit.

In a further advantageous embodiment of the invention, the base detection module and the first and second extension detection module are mechanically connected to a receiving module of the reporting device, wherein the second extension detection module is identical to the first expansion detection module, the second extension detection module compared to the first extension detection module by 180 ° ge rotates with the receiving module is mechanically connected. The first and second expansion sensing modules provide mechanical connection to the receiving module through the same side surface of the expansion sensing modules. Only the second expansion sensing module is rotated 180 degrees from the first expansion sensing module. In the rotated state of the second expansion detection module, in particular, the plungers of the first and second expansion detection modules are arranged offset to one another. _lg

Due to the fact that the detection of the position of the plungers is centered by the base detection module, only the base detection module has to comprise a printed circuit board with the sensors. The otherwise necessary printed circuit boards for the expansion acquisition modules can therefore be omitted, so that a cost reduction takes place.

Bundling the communication (e.g., information and control signals) to the base acquisition modules provides the user with improved, clear installation and configuration of the reporting devices.

Due to the modular design of the signaling device and the central evaluation of the plunger position in the basic detection module, a large number of different signaling devices (pushbuttons, switching devices, indicator lights, etc.) can be generated with just a few modules. As a result, a small variance of modules can be achieved. The sensors, in particular Hall sensors, are arranged on the printed circuit board in particular such that:

 the first sensor can detect only the first magnet of the first plunger in the first plunger position, the fourth sensor can detect only the first magnet of the first plunger in the second plunger position, the second sensor can detect only the first magnet of the second plunger in the first plunger position in that the fifth sensor can only detect the first magnet of the second plunger in the second plunger position.

 the third sensor can detect only the first magnet of the third plunger in the first plunger position, and / or

the sixth sensor can only detect the first magnet of the third plunger in the second plunger position. By means of the sensors, therefore, the present position and the presence of the plunger can be detected, so that from this a conclusion can be made on the state of the signaling device.

A proper mechanical connection exists when both modules have been properly connected together as intended.

The first and third sensor is arranged on the circuit board of the base detection module in particular laterally offset from the flight of the second plunger. The first, second and third sensors are in particular arranged in a V-shape.

In the following, the invention and embodiments of the invention will be described and explained in more detail with reference to the exemplary embodiments illustrated in the figures. Show it:

The individual signaling devices 1,2,3 are each connected by means of a communication unit with a communication bus 4. About the communication bus 4, the signaling devices

1,2,3 output signals and receive the internal device energy.

The first signaling device 1 is a rotary switch which can assume three different switching positions. The first

Signaling unit 1 includes as separate modules an actuator 14, a pickup module 13, a base detection module 10, and a first expansion sensing module 11 and a second expansion sensing module 12. The base sensing module 10, the first expansion sensing module 11, and the second expansion sensing module 12 are separately snap fit to the capture module 13 mechanically connected. The actuator 14, which comprises a switching element in the first signaling device 1, is also mechanically connected to the receiving module 13. About the switching element, a user can select three different switching positions. Depending on the present switching position, the signaling device 1 outputs a corresponding signal via the communication bus 4. The second signaling device 2 is a button, which can take two different switching positions. The second signaling device 2 comprises, as separate modules, an actuator 14, a recording module 13 and a basic detection module 10. Detection module 10 is mechanically connected to the receiving module 13 via a snap connection. The actuator 14, which comprises a sensing element in the second signaling device 2, is also mechanically connected to the receiving module 13. About the probe element, a user can select two different switching positions. Depending on the present switching position, the signaling device 2 outputs a corresponding signal via the communication bus 4. The third reporting device 3 is a switch. The third signaling device 3 comprises as separate modules an actuator 14, a receiving module 13, a base detection module 10 and a first extension detection module 11. The base detection module 10 and the first extension detection module 11 are separately mechanically connected via a snap connection with the receiving module 13. The actuator 14, which comprises two switching elements in the third signaling device 3, is also mechanically connected to the receiving module 13. About the respective switching element, a user can select two different switching positions. Depending on the present switching position, the signaling device 3 outputs a corresponding signal.

The receiving module 13, the base detection module 10 and, if present, the first expansion detection module 11 are of identical design in the first, second and third signaling devices 1, 2, 3. The second expansion detection module 12 is constructed identical to the first expansion detection module 11. It is only rotated by 180 ° connected to the receiving module 13.

Within the reporting system one of the signaling devices 1,2,3 is designed as a central module. This central module differs from the other signaling devices 1, 2, 3 in that it receives and evaluates the signals of the other signaling devices 1, 2, 3 of the reporting system via the communication bus 4. The base detection module of the central module further comprises a further communication port by means of which the central module can communicate with a higher-level bus system (eg Profibus, AS-Interface, IO-Link).

The first expansion detection modules 11 each include a first plunger 21 movably mounted in the first expansion detection module 11. The base detection modules 10 each include a second plunger 22 movably mounted in the base detection module 10. The second expansion detection module 12 includes a third plunger 23 movably mounted in the second expansion detection module 12.

About the spatial deflection of the individual plunger 21,22,23 a conclusion on the present state of the respective detection modules 10,11,12 can be obtained. For this purpose, the base detection module 10 includes sensors which can detect selectively defined positions (first and second plunger position) of the plungers 21,22,23.

3 shows a schematic representation of the arrangement of the movably mounted plungers 21, 22, 23 in the first signaling device 1 of FIG. 1, when no receiving module is mounted. The second and third signaling devices of Figure 1 are constructed analogously with respect to the existing detection modules.
