Hi, All
First time trying to interface a PLC to Mach3 ModBus, It's a A/B MicroLogix 1200, 1762-L40BWA FRN 11 .
It's talking to ModBus, But all I'm seeing is "Illegal Data Value", or "Illegal Function" on Mach3 ModBus Status: window/Line.
Using RSLogix500 software with proper ver. for ModBus, Set to 1200 Ser. C, Bul: 1762.
OK: Duuuu Question, Dose the Ladder Logic have to be setup in the PLC before setting it nto ModBus Mode.
Any one have a Solution.
Thanks, Chip
