regulation parameters and or a selection of type of regulation bearing regulation pressure regulation bearing regulation with slave pressure regulation and or a diagnosis of the modules of the valve cluster 11 b as for instance of the regulation modules 25 a and 25 b is possible at a central point using an operator device for example a notebook the operator device 57 is able to be connected with an operator device interface 58 of the communication means 14 b and is thus able to be coupled with the internal communication bus 21 then parameters from the operator device 57 may be saved in the valve cluster 11 b for example the regulation modules 25 aa and 25 ab or other modules furthermore a diagnosis is possible using the operator device 57 thus for instance the regulation modules 25 a and 25 b will transmit failure indications indications as regards the a number of already performed working cycles or other diagnostics data to the operator device 57 it will be clear that a wireless operation or diagnosis is also possible for instance using a operator device 59 which communicates in wireless manner with the communication means 14 b the putting into operation of the automation system 10 and diagnosis and or parameterizing of the regulation modules 25 a and 25 b is simplified by an auto identification concept the fluid power devices 17 or their associated means as for example the sensor devices 35 a 35 b and 35 c associated with the actuators 18 a through 18 c contain or form ident data transmission means 60 for sending the device identification data 61 a 61 b 61 c 61 d and 62 to receiving means 63 for the identification data 61.
