Operation Manual
It is required to login as an Administrator in PCM600 in order to change the password
policies.
Each user can change their own password, but only Administrator can reset the
passwords of other users.
On Factory restore, factory default usernames, passwords and password policies are
restored.
User authorization is disabled by default and can be enabled via the
LHMI Main menu/Configuration/Authorization/Passwords.
For user authorization for PCM600, see the PCM600 documentation.
Policy change and configuration is not allowed when the protection
relay is in offline mode in PCM600.
If the last ADMINISTRATOR password is lost, contact ABB's
technical customer support to retrieve the administrator level access.

Setting protection relay and communication

Setting the communication between protection relays and
PCM600
The communication between the protection relay and PCM600 is independent of the
used communication protocol within the substation or to the NCC. It can be seen as a
second channel for communication.
The media is always Ethernet and communication is based on TCP/IP.
Each protection relay has an Ethernet front connector for PCM600 access. Depending
on the station concept and the used station protocol, additional Ethernet interfaces
may be available on the rear side of the protection relay. All Ethernet interfaces can be
used to connect PCM600.
When an Ethernet based station protocol is used, the PCM600 communication can use
the same Ethernet port and IP address. The protection relay is able to separate the
information belonging to the PCM600 dialog.
