20.12 Test mode functionality TESTMODE IP1647-1 v320.12.1 Application M11407-3 v8The protection and control IEDs may have a complex configuration with manyincluded functions. To make the testing procedure easier, the IEDs include the featurethat 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 also enablesthe user to follow the operation of several related functions to check correctfunctionality and to check parts of the configuration, and so on.20.12.1.1 IEC 61850 protocol test mode GUID-82998715-6F23-4CAF-92E4-05E1A863CF33 v3The IEC 61850 Test Mode has improved testing capabilities for IEC 61850 systems.Operator commands sent to the IEC 61850 Mod determine the behavior of thefunctions. The command can be given from the LHMI under the Main menu/Test/Function test modes menu or remotely from an IEC 61850 client. The possible valuesof IEC 61850 Mod are described in Communication protocol manual, IEC 61850Edition 1 and Edition 2.To be able to set the IEC 61850 Mod the parameter remotely, the PSTsetting RemoteModControl may not be set to Off. The possible valuesare Off, Maintenance or All levels. The Off value denies all access todata object Mod from remote, Maintenance requires that the categoryof the originator (orCat) is Maintenance and All levels allow any orCat.The mod of the Root LD.LNN0 can be configured under Main menu/Test/Functiontest modes/Communication/Station communication/IEC61850 LD0 LLN0/LD0LLN0:1When the Mod is changed at this level, all components under the logical device updatetheir own behavior according to IEC 61850-7-4. The supported values of IEC 61850Mod are described in Communication protocol manual, IEC 61850 Edition 2. The IEC61850 test mode is indicated with the Start LED on the LHMI.The mod of an specific component can be configured under Main menu/Test/Function test modes/Communication/Station CommunicationIt is possible that the behavior is also influenced by other sources as well, independentof the mode, such as the insertion of the test handle, loss of SV, and IED configurationSection 20 1MRK 505 370-UUS ABasic IED functions516 Busbar protection REB670 2.2 ANSIApplication manual
