Basic IED functions

Test mode functionality TESTMODE

The protection and control IEDs may have a complex configuration with many included

functions. To make the testing procedure easier, the IEDs include the feature 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 also enables the

user to follow the operation of several related functions to check correct functionality and

to check parts of the configuration, and so on.

IEC 61850 protocol test mode

The IEC 61850 Test Mode has improved testing capabilities for IEC 61850 systems.

Operator commands sent to the IEC 61850 Mod determine the behavior of the functions.

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 values of IEC 61850

Mod are described in Communication protocol manual, IEC 61850 Edition 1 and Edition

To be able to set the IEC 61850 Mod the parameter remotely, the PST

setting RemoteModControl may not be set to Off. The possible values are

Off, Maintenance or All levels. The Off value denies all access to data

object Mod from remote, Maintenance requires that the category of 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/Function test

modes/Communication/Station communication/IEC61850 LD0 LLN0/LD0LLN0:1

When the Mod is changed at this level, all components under the logical device update

their own behavior according to IEC 61850-7-4. The supported values of IEC 61850 Mod

are described in Communication protocol manual, IEC 61850 Edition 2. The IEC 61850

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 Communication

It is possible that the behavior is also influenced by other sources as well, independent of

the mode, such as the insertion of the test handle, loss of SV, and IED configuration or

LHMI. If a function of an IED is set to Off, the related Beh is set to Off as well. The related

mod keeps its current state.
