Communication Between Pcm600 And Protection Relay - ABB RELION REX640 Operation Manual

Section 7
Commissioning
7.4.1.1

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.

Communication between PCM600 and 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 the FTP/FTPS
protocol. The Ethernet connector can be used.
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 service port X1.2 on the
protection relay's LHMI or, if an LHMI is not used, the HMI port X0 of the
communication module
• Indirect link via station LAN or remotely 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 to
match the IP addresses of the physical IEDs.
4. Technical keys of the IEDs in the PCM600 project are configured to match the
technical keys of the physical IEDs.
For successful protection relay engineering and usage, the workstation firewall TCP
and UDP port configurations should be checked, especially for IEC 61850 and FTP.
Other protocols are not used for engineering or they are optional.
