Abstract: A valve arrangement comprising at least one valve unit having several electrically operated valves, such unit possessing a bus station adapted to be connected with a serial bus controlled by a central station, the bus station being connected via control lines with electrical drives of the valves. The bus station comprises at least one serial connection adapted to be connected via a connecting cable with a serial/parallel converter of at least one further valve unit and/or at least one input module for the detection of sensor signals, the serial/parallel converter being connected via control lines with the electrical drives of the valves of this at least one further valve unit for the operation of the electrical drives of such valves by the bus station and/or via sensor lines with the sensors.

Abstract: An electronic control device for a modular valve range, which has a fluid manifold arrangement fitted with electrically controlled valves. The valves are controlled via at least one control module. Furthermore input and/or output modules and a central electronic control unit are provided, with which the individual modules are connected for control and/or data communication. The control unit is connected with the modules via a bus line system and each module possesses a programmed address decoder, means being provided for sequential configuration of the modules and for the automatic assignment of individual addresses for the individual modules. Accordingly the valve range may be designed and expanded just as may be desired, the connected modules automatically being recognized and provided with addresses.
