2 Introduction This document specifies the protocol implementation extra information for testing (PIXIT) of the IEC interface for Grid Software SimLab with firmware version 1.0. Together with the PICS and the MICS the PIXIT forms the basis for a conformance test according to IEC 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 The Ed column indicates if the entry is applicable for IEC Edition 1 and/or Edition 2. PIXIT for Association model As1 1 Maximum number of clients that can set-up 16 an association simultaneously As2 1,2 TCP_KEEPALIVE value. The recommended 10 seconds range is 1..20s As3 1,2 Lost connection detection time 12 seconds As4 - Authentication is not supported yet As5 1,2 What association parameters are necessary Transport selector for successful association Session selector Presentation selector AP Title AE Qualifier As6 1,2 If association parameters are necessary for Transport selector 0001 association, describe the correct values e.g. Session selector 0001 Presentation selector AP Title AE Qualifier 12 As7 1,2 What is the maximum and minimum MMS Max MMS PDU size 64KB PDU size Min MMS PDU size 16KB As8 1,2 What is the maximum start up time after a 300 seconds power supply interrupt As9 1,2 Does this device function only as test equipment? es Grid Software Inc.

Others will be discarded. b) If StNum is changed, messages with increasing StNum, will be accepted as valid. Others will be discarded. NOTE: If new StNum is less then previous and in time (500ms) is received increment of new StNum it will be accepted as valid. Duplicated message will be ignored, with or without the VLAN tag SPS, DPS, INS, ENS, ACT, ACD, BCR, VSS, MV, CMV, WE, DEL, SEQ, SPC, DPC, INC, ENC Arrays are not supported PIXIT for GOOSE performance Not Supported.
