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 User Management Tool.
Once a user is created and downloaded to the IED, that user can perform a Log on,
introducing the password assigned in the tool.
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/Settings/General Settings/HMI/Screen/Display Timeout) elapses, the IED
returns to Guest state, when only reading is possible. The display time out is set to
60 minutes at delivery.
If there are one or more users created with the User Management Tool and
downloaded into the IED, then, when a user intentionally attempts a Log on or
when the user attempts to perform an operation that is password protected, the Log
on window will appear.
The cursor is focused on the User identity field, so upon pressing the "E" key, the
user 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 "E"
key again. When it comes to password, upon pressing the "E" key, the following
character 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 "E" key again.
If everything is alright at a voluntary Log on, the local HMI returns to the
Authorization screen. 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, then the Log on window opens again, until either the user makes
it right or presses "Cancel".
