Hello Everyone,
I have a issue with communication between two different PLCs. So here is the facts, The Master PLC is Guard Logix 5069 with IP address 192.168.1.1. and we have a chiller with compact Logix (not sure of Model) with IP address 192.168.0.30.
Currently I am using the MODBUS TCP CLIENT AOIs available in Rockwell website, but it is Encountering a communication issue. The Modbus start to transfer the bit initially but after few minutes the module throughs, Overlap and Overload issue. which is breaks the steady communication. We tried to verify the polling interval at both end, and also increasing / decreasing the polling interval. Nothing works.
I tried to use the msg instruction, As it fails because of the IP.
Is there any solution for this Modbus client or can any suggest any other ways to attain an uninterrupted communication.
Thanks
