IEC 61850 protocol test mode

The function block TESTMODE has implemented the extended testing mode capabilities for
IEC 61850 Ed2 systems. Operator commands sent to the function block TESTMODE determine
the behavior of the functions. The command can be given remotely from an IEC 61850 client or
from the LHMI under the Main menu/Test/Function test modes/Communication/Station
Communication/IEC61850 LD0 LLN0/LD0LLN0:1. The possible values of the function block
TESTMODE are described in
2 .
There is no setting in PCM600 via PST for the TESTMODE function block.
The DataObject Mod of the Root LD.LNN0 can be set on the LHMI under Main menu/Test/
Function test modes/Communication/Station communication/IEC61850 LD0 LLN0/
LD0LLN0:1 to
When the setting of the DataObject Mod is changed at this level, all Logical Nodes inside the
logical device update their own behavior according to IEC61850-7-4. The supported values of
the function block TESTMODE are described in
Edition 2 . When the function block TESTMODE is in test mode the Start LED on the LHMI is
turned on with steady light.
The parameter

The parameter Mod can be set on the LHMI to the same values as for the DataObject Mod of
the Root LD.LNN0 to
Function test modes/ Differential protection/GeneratorDiff(87G,3Id/I>)/ GENPDIF(87G,3Id/
I>):1.
It is possible that the behavior of the function block TESTMODE is also influenced by other
sources as well, independent of the mode communicated via the IEC61850-8-1 station bus. For
example the insertion of the test handle into the test switch with its auxiliary contact is
connected to a BI on the IED and further inside the configuration to the input IED_TEST on the
function block TESTMODE. Another example is when loss of Service Values appears, or as
explained above the setting via the LHMI.
When setting via PST or LHMI the parameter
the function is not executed and the behavior (beh) is set to
override it. When a behavior of a function is
keeps its current state.
The IEC 61850-7-4 gives a detailed overview over all aspects of the test mode and other states
of mode and behavior. The status of a function block behavior
