Setting protection relay and communication

7.4.1 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.

7.4.1.1 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.
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

Operation Manual
Set up or get the IP addresses of the protection relays.
Set up the PC for a direct link or connect the PC or workstation to the network.
Configure the IP addresses in the PCM600 project for each protection relay.
The addresses are used for communication between protection relays and
PCM600.
If needed, the IP address for the protection relay is set.
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.
The protection relays' IP addresses in the PCM600 project are configured to
match the IP addresses of the physical IEDs.
