Technical manual
More than one input may be activated at the same time. In such cases the lower order
setting group has priority. This means that if for example both group four and group two
are set to be activated, group two will be the one activated.
Every time the active group is changed, the output signal GRP_CHGD is sending a pulse.
This signal is normally connected to a SP16GGIO function block for external
communication.
The parameter MaxNoSetGrp defines the maximum number of setting groups in use to
switch between.

Figure 303: Connection of the function to external circuits
The above example also shows the five output signals, GRP1 to 4 for confirmation of
which group that is active, and the GRP_CHGD signal which is normally connected to a
SP16GGIO function block for external communication to higher level control systems.
