15.1.4.1 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.
• Standard signals are always presented in the IED, see Table 320 .
• Hardware dependent internal signals are collected depending on the hardware
configuration, see
Table 321 .
Explanations of internal signals are listed in Table 322 .
