REX640 IEC 61850 Engineering Guide

Setting group control is global for the device. In the ABB engineering mode, it is possible to use six groups and handle them by binary input.

In the FPN mode, the number of setting groups is taken from the project SCD file. Since the relay has global setting group control for all logical devices, the biggest value is taken.
