15.12.2.1 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/SCREEN:1) 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
operation that is password protected, the Log on window opens.
The cursor is focused on the User identity field, so upon pressing 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, 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
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.
