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.
All communication is done over Ethernet using either IEC 61850 or FTP/FTPS protocol.
Each protection relay has an Ethernet interface connector on the front and optionally on
the rear side as well. The Ethernet connector can be used for communication with
PCM600.
When an Ethernet-based station protocol is used, 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
• 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.
4. Technical keys of the IEDs in PCM600 project are configured for each protection
relay to match the technical keys of the physical IEDs.
For successful protection relay engineering and usage, check the workstation firewall
TCP and UDP port configurations, especially for IEC 61850 and FTP. Other protocols are
not used for engineering and/or they are optional.
