Pixit For Association Model - Toshiba GRE110 Instruction Manual

Protcol Implementation eXtra Information for Testing (PIXIT) for IEC61850 interface in GRE series IED
・Introduction
This document specifies the protocol implementation extra information for testing (PIXIT) of the
IEC 61850 interface in GRE series IED with communication firmware MVM850-01 series version
upper than A (MVM850-01-A).
Together with the PICS and the MICS the PIXIT forms the basis for a conformance test according to
IEC 61850-10.
・Contents of this document
Each chapter specifies the PIXIT for each applicable ACSI service model as structured in IEC
61850-10.

PIXIT for Association model

ID Description
As1 Maximum number of clients that can
set-up an association simultaneously
As2 TCP_KEEPALIVE value
As3 Lost connection detection time
As4 Is authentication supported
As5 What association parameters are
necessary for successful association
As6 If association parameters are
necessary for association, describe the
correct values e.g.
As7 What is the maximum and minimum
MMS PDU size
As8 What is the maximum startup time
after a power supply interrupt
Value / Clarification
6
7200 seconds at the default setting.
Setting range is from 1s to 43200s.
After the KEEPALIVE is no response,
retrying 9 times every "X" seconds until
declaring that the association has been lost.
"X" is one tenth of TCP_KEEPALIVE value.
Ex. The lost connection detection time is 18s
(9 times x 2 s), when TCP_KEEPALIVE
value is 20 s.
