The cursor is focused on the User identity field, so upon pressing the key, one can
change the user name, by browsing the list of users, with the “up” and “down” arrows.
After choosing the right user name, the user must press the
key again. When it
comes to password, upon pressing the key, the following characters will show up:
“✳✳✳✳✳✳✳✳”. The user must scroll for every letter in the password. After all the
letters are introduced (passwords are case sensitive) choose OK and press the key
again.
At successful Log on, the local HMI shows the new user name in the status bar at the
bottom of the LCD. If the Log on is OK, when required to change for example a
password protected setting, the local HMI returns to the actual setting folder. If the
Log on has failed, an "Error Access Denied" message opens. If a user enters an
incorrect password three times, that user will be blocked for ten minutes before a new
attempt to log in can be performed. The user will be blocked from logging in, both
from the local HMI and PCM600. However, other users are to log in during this
period.

15.13.2 Application
Authority status (ATHSTAT) function is an indication function block, which 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)
The two outputs of ATHSTAT function can be used in the configuration for different
indication and alarming reasons, or can be sent to the station control for the same
purpose.
