There are four IED variant specific setting groups. Parameters can be set
independently for each setting group.
The active setting group (1...4) can be changed with a parameter. The change of an
active setting group can also be made via a binary input if the binary input is enabled
for this. To enable the change of an active setting group via a binary input, connect
a free binary input with SMT to the ActSG input of the SGCB-block.

The active setting group defined by a parameter is overridden when a binary input is
enabled for changing the active setting group.
