REF542plus time stamp issue on IEC 61850 connect.
We have around 500 nos. of REF542plus relay connected to ABB 800xa using 8 nos. of redundant IEC 61850 connect.
We are experiencing time stamp issue on 2 nos. of REF542plus relay communicating using IEC 61850 communication protocol with IEC 61850 connect.
Relay time synch with GPS and all other signals from the same relay are updating with current good time stamp(Screenshot attached).
Time stamp for few signal are updating with year 2070 and 1970.
These events always appearing at top of event list, causing limitation to see the latest alarm on top.
Thanks in advance for quick reply.
