IEC 61850 GOOSE ANALOGS
The L60 Line Phase Comparison System is provided with optional IEC 61850 communications capability.
This feature is specified as a software option at the time of ordering. Refer to the
Ordering section of chap-
ter 2 for additional details. The IEC 61850 protocol features are not available if CPU type E is ordered.
The IEC 61850 GGIO3 analog input data points are displayed in this menu. The GGIO3 analog data values are received
via IEC 61850 GOOSE messages sent from other devices.
