Internal Signals - Hitachi Relion 650 Series Technical Manual

Section 14
Basic IED functions
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.

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.
• Standard signals are always presented in the IED, see
• Hardware dependent internal signals are collected depending on the hardware configuration,
see
Explanations of internal signals are listed in
