Section 4 User management
4.1 Local user account management
Four factory default user accounts have been predefined, each with different rights
and default passwords. The roles for these four user accounts are the same as the
username.
• VIEWER
• OPERATOR
• ENGINEER
• ADMINISTRATOR
The default passwords in the protection relay delivered from the factory can be
changed with Administrator user rights or by the users themselves. Relay user
passwords can be changed using the LHMI or IED Users in PCM600.
Each protection relay supports four roles and eight user accounts. Each user can be
mapped to only one role.
IED Users in PCM600 is used to manage the local user accounts.
• User accounts can be created under any role.
• Administrator needs to share the default password generated for the user
account by the tool with the users and recommend the user to change the
password.
• The user accounts’ password can be changed by the users from IED Users or
from the LHMI.
• Administrator can reset the user passwords.
The user account information is written to the protection relay from IED Users in
PCM600. The user account information is securely maintained in a local database
in the protection relay.
Any user logging into the protection relay from LHMI or PCM600 (FTPS/USB) is
authenticated based on the user account information and this user’s rights are
defined by the user’s role.
