When the subscriber receives GOOSE message updates, the subscribed data is copied to the
internal variables that can be monitored and recorded in the device like any other measured
value. When the subscriber does not receive updates, or the declared message live time has
expired, or the data set differs from the subscriber setup, the internal variables are zeroed
and the non-active status is indicated in the subscription status.
The subscription status can be monitored from an IEC 61850 client via the GOOSE subscriber
logical nodes CTRL/sbsLGOS1-CTRL/sbsLGOS20, or from a Modbus client application via the
GOOSE subscriber status register (see the PM180 Modbus Reference Guide for the register
location).
To configure the GOOSE subscriber:
1. Select IEC 61850 Setup from the Meter Setup menu, and then click on the GOOSE
