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. The result is that the central bus station may have further valve units connected with it via a respective cable without the need for a respective separate bus station so that any desired further modifications of the system are possible.
