8.4 Setting protection relay and communication
8.4.1 Communication between PCM600 and the protection relay
The communication between the protection relay and PCM600 is independent of
the used communication protocol within the substation or to the NCC.
Each protection relay has an Ethernet interface connector on the rear and a USB
interface connector on the front. Both connectors can be used for communication
with PCM600.
Communication over Ethernet (rear port) is done using either IEC 61850 or FTP/
FTPS. Communication over the front port USB is done over Media Transfer
Protocol (MTP).
When an Ethernet-based station protocol is used for rear port communication, the
same Ethernet port and IP address can be used for PCM600 communication.
Two basic variants have to be considered for the connection between PCM600 and
the protection relay.
• Direct point-to-point link between PCM600 and the protection relay's front
port. When communicating over the front port USB, IP is not relevant and by
default this is seen as 0.0.0.0.
• Indirect link via station LAN or from remote via network
1. If needed, the IP address for the protection relay is set.
2. A PC or workstation is set up for a direct link (point-to-point), or the PC or
workstation is connected to the LAN/WAN network.
3. The protection relays' IP addresses in the PCM600 project are configured for
each protection relay to match the IP addresses of the physical IEDs (rear
port).
4. Technical keys of the IEDs in PCM600 project are configured for each
protection relay to match the technical keys of the physical IEDs.
