CI867 Modbus TCP Connection down


The CI867 communication with other Slave PLCs (ABB AC500) are okay. But we have some thrird pary power meter as slave on the same network. The connection is getting down randomly, many be once in 15Sec or 30Sec. When I use a modbus master simulator, Noticed this slave(Power Meter) is not responding for all the quires, It may miss 1 in be around 20-50 Quires.

Its a Red Blink and healthy again !
So is it possible to hide or not alarm if the connection is down for one missing response from the Slave. I tried to play with the TimeOut and Number of quires and so.. Not successful...
Any Idea about this ?

We had 2 problem.
1. the slave the master id was 1 and another slave has an id 1.
Made different id.

2. The address which we are pooling on the slave have some issue so the maker asked to pool another address.
