15.13.6 Operation principle
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.
