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
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
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.
