REX615 Operation Manual

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.

To configure the physical connection and the IP addresses:

  1. Set up or get the IP addresses of the protection relays.
  2. Set up the PC for a direct link or connect the PC or workstation to the network.
  3. Configure the IP addresses in the PCM600 project for each protection relay.
    The addresses are used for communication between protection relays and PCM600.
