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 Table
Explanations of internal signals are listed in
