Superposed control of compressor 13 on the basis of time criteria is preferably employed at low outside temperatures, that is, when the temperature at the cylinder head of compressor 13 rises only slowly by virtue of good heat dissipation to the surroundings while compressor 13 is turned on and drops rapidly once again while compressor 13 is turned off.

The master position is stored or latched with the positive edge of the sensor signal and transmitted by way of the bus 11 to the superior-level control 14 .

It is necessary that the higher-level control means knows precisely when an IO link sensor acquires measurement data, or an IO link actuator performs an action, in order to be able to control and monitor a process sequence in an error-free manner.

In the area of field buses, such as the Profibus Decentralized Peripherals (DP), methods and control systems are known in which a superordinate controller is connected to a field bus and the field bus is in turn connected to automation units, which represent a decentralized peripheral system.

These peripheral access errors can then be detected, for example, by the useful data companions Input/Output Operations Per Second (IOPS) and Input/Output Control System (IOCS), where are customary in the case of a PROFINET IO protocol, and a superordinate controller or the main module thus obtains information about access problems of the subordinate peripheral system.

Wireless networks that have a supervisory control, which collects data from individual Clients in the wireless network and distributes data to Clients on the wireless network, are well-known.

Furthermore, the fact that a higher-level control is not needed, allows the wireless network to be built with a reduced number of components.

Such a higher-level control could be, for example, an SPS (Storage Programmable Control)-control, which is connected to a Master-Client of the wireless network, for example, via a data interface.

In particular, the exchange of data, in which a Client makes the wireless network available and in which the other Clients require the wireless network, occurs via this supervisory control.

Thus for example a master control at the control interface may transmit a switching signal for deactivating or activating the instrumentality.

By way of the valve cluster communication means it is possible for the device identification data received at the receiving means in accordance with the invention to be passed on to further components of a automation system, as for example a parameterizing tool, to a master control or to a diagnostic device or the like.

It is an advantage for the switching state at the switching output to be further reported by way of the control interface, for example to a master control.

The valve module for example receives control signals from a master control for switching its valve.

Finally, the IO link devices communicate through the IO link master with the higher-level control means of the automation system.

It is also possible as an alternative to use a higher level controller for true master-slave operation using a torque-compensation controller.

Another function enables the communication with the superimposed controller and the operating console.

The raw measured value data are made available to the higher-level controller for analysis.

The valve module can however receive the switching signal for example also at the control interface from the master control.

The measured values can be processed in the I/O system or in the higher-level controller.

The IO-Link master provides the interface to the higher-level controller (PLC) and controls the communication with the connected IO-Link devices.

Control strategies for the control of highly-dynamic drives, the coupling of movement axes and the interfaces to invertors (current or instantaneous interface) and for superimposed control (VME 24) are generally known.

If further switching means are required, as for example a clamping means or a brake for clamping or a brake of a power tapping means of the instrumentality, valves for the interruption of fluid connection for example in the case of failure or the like it is necessary for additional ducts to be placed between the such means and the master control.

Like all measured terminal data, the harmonic content can be read via the process data and processed by the higher-level controller.

Alternatively or additionally, a separate communication path can be established for the synchronization data between the higher-level controller and the IO clock, for example, through a Bluetooth or infrared connection.

This may be carried out in such a way that the at least one manipulated variable resulting from the combination of the superimposed control and the regulation, for example, the at least one heater voltage, does not depart from a corridor around a pilot control value.

The regulating device 40 receives a target value K for the cooling power either manually from an operator or from a superimposed control and/or regulating device 50 for controlling and/or regulating the cooling power.
