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.
