Application
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 2.
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.
