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 488 .
• Hardware dependent internal signals are collected depending on the hardware
configuration, see
Table 489 .
Explanations of internal signals are listed in Table 490 .
Table 488: SELFSUPEVLST standard internal signals

Table 490: Explanations of internal signals
Name of signal Reasons for activation
Internal Fail This signal will be active if one or more of the following
internal signals are active; Real Time Clock Error, Runtime
App Error, Runtime Exec Error, SW Watchdog Error, File
System Error
Internal Warning This signal will be active if one or more of the following
internal signals are active; IEC 61850 Error, DNP3 Error
Real Time Clock Error This signal will be active if there is a hardware error with the
real time clock.
