Main/supplementary setpoint and setpoint modification

Description
The supplementary setpoint can be used to incorporate correction values from lo-
wer-level controllers. This can be easily carried out using the addition point for the
main/supplementary setpoint in the setpoint channel. Both variables are imported
simultaneously via two separate or one setpoint source and added in the setpoint
channel.
