15.12.4.1 Authorization handling in the IED
At delivery the default user is the SuperUser. No Log on is required to operate the IED
until a user has been created with the IED User Management..
Once a user is created and written to the IED, that user can perform a Log on, using the
password assigned in the tool. Then the default user will be Guest.
If there is no user created, an attempt to log on will display a message box: “No user
defined!”
If one user leaves the IED without logging off, then after the timeout (set in Main
menu/Configuration/HMI/Screen/1:SCREEN) elapses, the IED returns to Guest
state, when only reading is possible. By factory default, the display timeout is set to 60
minutes.
If one or more users are created with the IED User Management and written to the
IED, then, when a user attempts a Log on by pressing the key or when the user
attempts to perform an operation that is password protected, the Log on window opens.
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.
