CHAPTER 7: IEC 61850 PROTOCOL 7.1 IEC 61850 GENERIC SUBSTATION STATE EVENT (GSSE)
GEK-106310-AF F650 DIGITAL BAY CONTROLLER 7-3
Figure 7-1: Remote communication
Default Value (1 to 32) selects the logic state for this point if the local relay has just completed startup or the remote device
sending the point is declared to be non-communicating. The following choices are available:
• ON value defaults the input to Logic 1.
• OFF value defaults the input to Logic 0.
• Latest OFF freezes the input in case of lost communications. If the latest state is not known, such as after relay power-
up but
before the first communication exchange, the input defaults to Logic 0. When communication resumes, the
input becomes fully operational.
• Latest ON freezes the input in case of lost communications. If the latest state is not known, such as after relay power-
up but
before the first communication exchange, the input defaults to Logic 1. When communication resumes, the
input becomes fully operational.
Destination MAC Data (1 to 3): If a valid multicast Ethernet MAC address is entered, this address is used as the destination
MAC address for GSSE messages. If a valid multicast Ethernet MAC address is not entered (for example, 00 00 00 00 00 00),
the device uses the source Ethernet MAC address as the destination, with the multicast bit set.
GSSE RemDevice (1 to 24) MAC Data (1 to 3) is used to filter receiving messages.
GSSE PORT sets the network port through messaging will be done. Possible values are "Port A", "Port B" or "Both".
