Test mode functionality TEST

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 IEC61850 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 IEC61850-7-4. The supported values of IEC61850 Mod
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 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.
