Figure 250: Self supervision, function block internal signals
Some signals are available from the INTERRSIG function block. The signals from
INTERRSIG function block are sent as events to the station level of the control
system. The signals from the INTERRSIG function block can also be connected to
binary outputs for signalization via output relays or they can be used as conditions for
other functions if required/desired.
Individual error signals from I/O modules can be obtained from respective module in
the Signal Matrix tool. Error signals from time synchronization can be obtained from
the time synchronization block INTERSIG.

Internal signals

SELFSUPEVLST function provides several status signals, that tells about the
condition of the IED. As they provide information about the internal status of the IED,
