Input switchgroups (SWGRP)

Switchgroups are used for connecting input signals to the inputs of the function
blocks. Switchgroups allow the connection of one input signal to several function
block inputs. Refer to Fig. 4.1.3.-1 for all the signals available for each input
switchgroup. The settings can be found in Main
menu\Configuration\Input SWGRP.
