17.12.2.1 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
key or when the user attempts to
perform an operation that is password protected, the Log on window opens.
