4.1.2. 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
.
Fig. 4.1.2.-1 The input signal is routed with the switchgroup to one or several
function block input(s)
Note that the symbol O/C (overcurrent) includes overcurrent function blocks I>, I>>
and I>>>. The E/F (earth fault) symbol includes all three earth fault function blocks
Io>, Io>> and Io>>>, for example the Reset 1 signal resets all the three stages.
The symbols O/C and E/F are used in the overview diagrams of the signal routings
and in the HMI menus.
