Description
Available as of firmware version A.00.28.09.
determines the set-point value settings and describes the external set-point value as a percentage:
Internal = analog - the set-point value settings is assigned by the analog set-point value signal that is
created
External = digital via serial interface
do not use this command if you are using a bus device (PROFIBUS, deviceNet, etc.). The digital set-point
value settings via the serial interface has a higher priority.
