- a communication module 41 is provided in the actuator 10 as a signal transmitter and / or signal detection means, which serves as a communication means and is connected to the connections 34, 35 e.g. is coupled with an electrical transformer. It is thus connected to the electrical connecting lines 28, 29.
- the communication module 41 receives measured values from the sensors 37, 38 via connections 42, 43, which the communication module 41 modulates as voltage signals with the aid of a modulator to the voltage UV. For this purpose, a pulse width, pulse frequency or other modulation method is used, for example. It is also possible that the communication module 41 digitally encodes the message signals with a coding device and e.g. sends to the valve arrangement 12 as serial data telegrams.

- the valve arrangement 12 has a communication module 44 for receiving the message signals on the signal connection SV, that is coupled to the connections 31, 32, for example via a measuring resistor connected in series with the energy source 30, and thus listens to the modulated and / or coded signal signals transmitted on the electrical connecting lines 28, 29, so to speak, and with the aid of a demodulator and / or decoder determined from the voltage UN.
- the communication module 42 transmits the message signals to the control module 39 via a connection 45, so that the signal connection SV is established overall between the sensors 37, 38 and the control module 39.

- FIG. 2 shows valve arrangements 12a and 12b, which with actuators 10a and 10b via compressed air lines 13a, 14a and 13b, 14b are connected.
- the bus 63 and the compressed air feed line 22 shown symbolically for a compressed air supply system (not shown) are passed through the valve arrangements 12a and 12b, so that further valve arrangements designed as modules and not shown for reasons of clarity can be attached to the valve manifold 60.
- the control module 61 can be a separate control device or form part of the valve battery 60.
- the actuators 10a and 10b are constructed essentially the same as the actuator 10 according to FIG. 1, but do not contain the display element 46. Furthermore, the valve arrangements 12a and 12b are constructed essentially the same as the valve arrangement 12. The same or equivalent components are shown in FIG 2 therefore provided with the same reference numerals as the corresponding components in FIG. 1, the letters “a” or “b” added in some cases illustrating an assignment of the respective component to the actuator / valve arrangement combinations 10a, 12a or 10b, 12b.
- valve arrangements 12a and 12b do not have their own control module, but are instead via bus interface modules 64a, 64b connected to the fieldbus 63 and controlled by the control module 61.
- the bus interface modules 64a and 64b and the communication modules 44a, 44b assigned to them can each be combined to form an assembly, for example an integrated circuit.
- FIG. 3 essentially shows the arrangement known from FIG. 1.
- an electrical connection between the valve arrangement 12 and the actuator 10 is provided via an electrically conductive compressed air line, the compressed air line 13.
- the second electrical connection between the valve arrangement 12 and the actuator 10 leads via a common ground potential MP, for example a common ground, to which the electrically conductive connections 16 and 18 are each connected.
- MP common ground potential
- the housings of the actuator 10 and the valve arrangement 12 are each connected to the ground potential MP and the second electrical connection is established in this way.
- an electrical conductor is therefore not required in a compressed air line 14c fluidly connecting the connections 16 and 18.
- the actuators 10a and 10b have only controlled electrical components, for example electrical actuators, or only reporting components, for example sensors.
- FIG. 4 A particularly simple variant of the exemplary embodiment from FIG. 1, shown only schematically, is shown in FIG. 4, in which the signaling means of the actuator set impressed current flows on the signal connection to the valve arrangement.
- the energy source 30 of the valve arrangement 12 supplies the actuator 10 with the voltage UV via the electrical connections 28, 29, which lead via the compressed air lines 13, 14, to the sensors 37, 38 and to the sensors 37, 38 connected in parallel in the electrical connections 34, 35 drops in each case to these current sources 50, 51 connected in series and serving as signaling means.
- the sensors 37, 38 are, for example, reed switches, magnetoresistive elements or Hall sensors which become electrically conductive when the piston 27 approaches and are otherwise electrically non-conductive or not very conductive.
- the current sources 50, 51 are, for example, so-called current diodes, which are continuous in their forward direction up to a predetermined current flow, that is to say set an impressed current. It is also possible for the current sources 50, 51 to be formed by transistor circuits which set an impressed current flow or for the sensors 37, 38 to set impressed currents per se, for example by their respective resistance value, and thus in themselves form the signaling means of the actuator 10.
- the level of the voltage Um is scanned and evaluated by signal detection means, which are not shown in detail.
- an actuator contains only reporting electrical components, only transmission means, for example a modulator, are required in its communication module, and only receiving means, for example a demodulator, is required in the valve arrangement assigned to the actuator or the control module assigned to it.
- an actuator has only controlled, but no reporting, electrical components, only one transmitting device, for example a modulator, and only one receiving device, for example a demodulator, are required in the actuator associated with the communication module.
- an actuator and a valve arrangement communicate bi-directionally, for example using a fieldbus protocol
- their respective communication Modules both transmit and receive devices necessary, regardless of whether the respective actuator has only controlled or only reporting electrical components.
- the respective control module can control the flow of information via a bidirectional connection and, for example, send diagnostic queries to the actuator.
- the communication modules 44a, 44b and the energy sources 30 could not be integrated in the valve arrangements 12a, 12b, but could form part of the control module 61.
- the electrical connecting lines 28a, 29a, 28b and 28b would then be led through the valve arrangements 12a, 12b and would be connected to the control module 61, for example via a parallel bus between the control module 61 and the valve arrangements 12a, 12b.
- bus interface modules 64a, 64b and the communication modules 44a, 44b respectively assigned to them could be combined to form a separate assembly which can be arranged, for example, on a valve battery or on a control module.
- the connections 42, 43 for the sensors 37, 38 are wired or wireless connections. In the case of wireless connections, the sensors 37, 38 would be configured, for example, as so-called transponders.
- the electrical components of the actuator 10, for example the communication module 42 and the energy converter 33, can at least partially be combined to form a common assembly. This can be arranged, for example, on the cylinder 11, for example in a cylinder cover of the cylinder 11.
- the compressed air lines 13, 14 each have only a single electrical conductor. However, it is also possible in principle that further electrical conductors are provided for other purposes.
