The communication between the IED system 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 FTPS/HTTPS protocol.
SSC600 has multiple Ethernet connectors for communication. 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 IED system.
- Direct point-to-point link between PCM600 and the IED system's local port / remote port
- Indirect link via station LAN or from remote via network
- If needed, the IP address for the IED system 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 IED system' IP addresses in the PCM600 project are configured for each IED to match the IP addresses of the physical IEDs.
- Technical keys of the IEDs in PCM600 project are configured for each protection IED to match the technical keys of the physical IEDs.
For successful protection IED 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.
