• 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

station bus.
