Abstract:
A fluid power valve arrangement with at least one solenoid valve whose solenoid is connected or able to be connected via only two control lines with an electrical control and/or communication device. The solenoid valve has integrated in it a non-volatile storage device containing identification data of the solenoid valve, and furthermore a modulator for modulation of data of the solenoid valve in the two supply lines. The control and/or communication device possesses a demodulator for demodulation of the modulated data.
