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 473 .
• Hardware dependent internal signals are collected depending on the hardware
configuration, see
Table 474 .
Explanations of internal signals are listed in Table 475 .
Table 473: SELFSUPEVLST standard internal signals

Internal Warning Internal warning status
Real Time Clock Error Real time clock status

Runtime App Error Runtime application error status
Runtime Exec Error Runtime execution error status
IEC61850 Error IEC 61850 error status
SW Watchdog Error SW watchdog error status
Setting(s) Changed Setting(s) changed
Setting Group(s) Changed Setting group(s) changed
Change Lock Change lock status

Table 475: 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.
