Figure 284: 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 INTERRSIG.
16.2.4.1 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, they are also called internal
signals. The internal signals can be divided into two groups.
