Hi All.
I am trying to relocate a simple MODBUS system from a MicroLogix 1400 (on channel 0 set as a Modbus RTU Master) to an CompactLogix SM2 Module.
Image below shows set up of read and write to Node 1 of a simple RTU slave. As simple as it gets. Read some words from an address, Write some words to address.
I am struggling to find any documentation to do the same with the SM2. AB assure me it can be done but all the docs I find talk exclusively of talking to AB drives (in slave mode). Currently wading through the SM2 manual now.
Any advise welcomed!
Thanks.
Graeme.
