REC615 and RER615 DNP3 Communication Protocol Manual

Fault record data objects contain registered values captured simultaneously by the relay's protection at the moment of a fault. The fault record objects internally belong to IEC 61850 logical node FLTRFRC1.

The FLTRFRC1 objects can be found as DNP3 analog input values in the DNP3 point list. There are two alternative DNP3 data objects for each captured fault record object in the point list. A different trailing text for the objects is shown in the object's name, either “Ev-Upd” (event updated) or “Record” (read on demand).
