automatan Posts: 57 Rating: (1)	Hi , I am working on CP to CP communication between CU412-5H and CPU313C. I am using BSEND and BRCV function. Hardware are CP443-1 and CP343-1. I want to switch over communication based on which one is MASTER RACK. Individually i can communicate between both the RACKs. But, I have to switch LOCAL ID based on MASTER RACK CPU. Please guide me. Thanks.
