Setpoint channel

Setpoint addition
Fine tuning (correction variable) often needs to be carried out on site for applications in which
the command variables are generated by central control systems.
You achieve the correction variable using the addition point for the main and additional setpoint
in the setpoint channel. Both variables are imported simultaneously via two separate or one
setpoint source and added in the setpoint channel.
