21.11 Test mode functionality TESTMODE IP1647-1 v321.11.1 Application M11407-3 v9The protection and control IEDs may have a complex configuration with manyincluded functions. To make the testing procedure easier, the IEDs include thefeature that allows individual blocking of a single-, several-, or all functions.This means that it is possible to see when a function is activated or trips. It alsoenables the user to follow the operation of several related functions to checkcorrect functionality and to check parts of the configuration, and to check parts.21.11.1.1 IEC 61850 protocol test mode GUID-82998715-6F23-4CAF-92E4-05E1A863CF33 v5The function block TESTMODE has implemented the extended testing modecapabilities for IEC 61850 Ed2 systems. Operator commands sent to the functionblock TESTMODE determine the behavior of the functions. The command can begiven remotely from an IEC 61850 client or from the LHMI under the Main menu/Test/Function test modes/Communication/Station Communication/IEC61850LD0 LLN0/LD0LLN0:1. The possible values of the function block TESTMODEare described in Communication protocol manual, IEC 61850 Edition 1 andEdition 2.There is no setting in PCM600 via PST for the TESTMODE function block.To be able to set the function block TESTMODE remotely, thesetting via path on LHMI and in PST: Main menu/Configuration/Communication/ Station Communication/IEC61850-8-1/IEC61850-8-1:1RemoteModControl may not be set to Off. Thepossible values of the parameter RemoteModControl are Off,Maintenance or All levels. The Off value denies all access tofunction block TESTMODE from remote, Maintenance requiresthat the category of the originator (orCat) is Maintenance and Alllevels allow any orCat.The DataObject Mod of the Root LD.LNN0 can be set on the LHMI under Mainmenu/Test/Function test modes/Communication/Station communication/IEC61850 LD0 LLN0/LD0LLN0:1 to On, Off, TestBlocked,Test or Blocked.When the setting of the DataObject Mod is changed at this level, all Logical Nodesinside the logical device update their own behavior according to IEC61850-7-4.The supported values of the function block TESTMODE are described inCommunication protocol manual, IEC 61850 Edition 2. When the function blockTESTMODE is in test mode the Start LED on the LHMI is turned on with steadylight.1MRK 505 393-UEN B Section 21Basic IED functionsLine differential protection RED650 2.2 IEC 415Application manual
