Functionality

To safeguard the interests of our customers, both the IED and the tools that are
accessing the IED are protected, by means of authorization handling. The authorization
handling of the IED and the PCM600 is implemented at both access points to the IED:
• local, through the local HMI
• remote, through the communication ports
Settings
The function does not have any parameters available in Local HMI or Protection and
Control IED Manager (PCM600).
Operation principle
There are different levels (or types) of users that can access or operate different areas
of the IED and tools functionality. The pre-defined user types are given in
Table 451: Pre-defined user types
User type
SystemOperator
ProtectionEngineer
DesignEngineer
UserAdministrator
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.
