The recovery of the valve positions reported back in binary format
(S1 to S3 and S4) or the analog position signal is described in the
Operating Instructions in chapter "Position measuring system". The
analog target position signal (resolution: 0.1 mm) is available as
acyclical value/parameter in the büS/CANopen network.
