We are communicating REF615 with CI868 using Goose, We have configured system, when we send command one IED to close breaker, we found that other breaker that is connected with other IED operate, Some time 2 or 3 breakers operate that are not connected with concerned IED.
I have checked all mapping and found normal.
While we are communicating other type of IEDs (REC, RET and REB) with same CI868 that are working fine.
Can you please check the Application configuration view of the relays. I guess inter relay tripping will be assigned to more than one of the relays. Or can you confirm the outcome of 2 cases for more understanding: first by operating the breaker locally or second by operating it from CET.
Have you checked the MAC-Address configured to each GOOSE message? Probably there is a repeated MAC address. If all breakers are in the same substation, I suggest you to configure a different address for each GOOSE message. It is also important to configure VLANs for the different substaions in your project (not mandatory, but important for security reasons, like you mentioned: operating several equipments with one command)
