When a IED is configured to a PCM600 project, the connection between the IED and the tool can be established using a point-to-point link between the IED local port / remote port and the computer or by connecting the computer to the IED rear port over an Ethernet station bus. In PCM600, the local, remote or rear communication port can be selected from the project structure.
When using the local port / remote port, DHCP server functionality must be activated in the computer network adapter settings to get the IP address from the IED. Alternatively, the computer network adapter IP address can be set manually to the same subnet range as the local port / remote port.
- Check that the settings are correct to ensure successful configuration access to the IED.
- Computer port settings must match IED settings (IP address, subnet mask, DHCP).
- Any fire wall in the computer or in the network must pass required communication services.
- When using the local port / remote port and switching the connection from the computer to another IED, it takes some time before the computer refreshes the IED's MAC address for local port / remote port IP address automatically. The MAC address can also be reset manually by clearing the computer ARP table.
