IED user authorization is disabled by default. IED user passwords can be changed in LHMI, WHMI and using the IED Users tool in PCM600.
Note: Local passwords can be changed only via the LHMI. Remote passwords can be changed via the LHMI or WHMI or with PCM600.
If the IED-specific Administrator password is forgotten, ABB can provide a onetime reliable key to access the IED. For support, contact ABB. The recovery of the Administrator password takes a few days.
Enable IED user authorization at Main Menu > Configuration > Authorization > Passwords in LHMI or WHMI.
Use the IED Users tool in PCM600 to change the passwords.
This tool cannot be used to add or change users.

When communicating with the protection relay with PCM600 tools and with the relay authentication enabled, the relay username and password must be given when prompted. When setting the technical key, the username and password must be given twice.
Figure 3. User login
Tip: If the PCM600 authentication has been enabled in PCM600 System Settings, a relay user can be linked to the current PCM600 user by selecting the Remember me check box in the Login dialog. After that, the user credentials are no longer asked at tool communication as logging in PCM600 also provides the authentication credentials to the protection relay.
