20.4.6 Operation principle
SEMOD158543-4 v5
Authority status (ATHSTAT) function informs about two events related to the IED
and the user authorization:
• the fact that at least one user has tried to log on wrongly into the IED and it
was blocked (the output USRBLKED)
• the fact that at least one user is logged on (the output LOGGEDON)
Whenever one of the two events occurs, the corresponding output (USRBLKED or
LOGGEDON) is activated. The output can for example, be connected on Event
(EVENT) function block for LON/SPA.The signals are also available on IEC
61850 station bus.
