Introduction
This document specifies the protocol implementation extra information for testing (PIXIT) of the IEC 61850
interface in the client system: "ME-RTU" with firmware version "90.34", further referred to as "client".
Together with the PICS and the MICS the PIXIT forms the basis for a conformance test according to
IEC 61850-10.
The following chapters specify the PIXIT for each applicable ACSI service model as structured in
IEC 61850-10 and the "Conformance Test Procedures for Client System with IEC 61850-8-1 interface".
