The IED users can be created, deleted and edited only with the IED User Management
within PCM600. The user can only LogOn or LogOff on the local HMI on the IED,
there are no users, groups or functions that can be defined on local HMI.
Only characters A - Z, a - z and 0 - 9 should be used in user names and
passwords.
The maximum of characters in a password is 12.
At least one user must be included in the UserAdministrator group to
be able to write users, created in PCM600, to IED.

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
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
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
