Some signals are available from the INTERRSIG function block. The signals from this
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 TIMEINTERRSIG.
4.2.2.1 Internal signals
Self supervision 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
Table 15.
• Hardware dependent internal signals are collected depending on the hardware
configuration, see Table 16.
Explanations of internal signals are listed in Table 17.
