Manager (PCM600)
20.4.6 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. 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.
