8 SERIES PROTECTIVE RELAY PLATFORM – COMMUNICATIONS GUIDE
This section contains the Protocol Implementation eXtra Information for Testing (PIXIT) for
the IEC 61850 interface in the 8 Series relays.
Version 1.0
Date: July 23, 2015
This document specifies the protocol implementation extra information for testing (PIXIT)
of the IEC 61850 interface in 8 Series relays.
Together with the PICS and the MICS, the PIXIT forms the basis for a conformance test
according to IEC 61850-10. The PIXIT entries contain information which is not available in
the PICS, MICS, TICS documents or SCL file.
Each table specifies the PIXIT for applicable ACSI service model as structured in IEC 61850-
10. The "Ed" column indicates if the entry is applicable for IEC 61850 Edition 1 and/or
Edition 2.
