The IP address and subnet mask of the IED object in PCM600 must match the front and rear port of the protection relay (physical IED) to which the PC is connected. The IP address of the protection relay can only be set via the LHMI or Parameter Setting tool in PCM600. The PC and protection relay need to be on the same subnet.
There are two alternatives to set the IP address of an IED object in PCM600.
- On the first page of the wizard when including a new IED into a project.
- In the IP address box of the IED's Object Properties dialog box.
Choosing between the two ways depends on when the IP address is set. Typing the IP address via the IED's Object Properties dialog box is possible at any time while entering it via the configuration wizard can only be done when adding the IED object.
