Abstract
A valve controller for electrically actuating at least one valve drive, with a control circuit, which is designed to influence an electric energy flow between an electric source and the valve drive and which includes a bus interface for communication with a superordinate control arrangement () as well as a sensor means, which is designed to determine physical variable of the energy flow changeable by electrically actuating the valve drive as well as for providing a sensor signal dependent upon the determined physical variable to the control circuit wherein the control circuit is designed to determine a status value for the valve drive based on the sensor signal and at least one characteristic value of a physical variable from the group: energy flow duration, energy flow voltage, energy flow current, fluid pressure and is designed to provide the status value to the bus interface.
