I'm currently working on an application where I need to communicate to a Square-D SY/MAX system with an Allen Bradley controllogix processor.

Will I be able to communicate through modbus plus protocol using Prosoft MVI56-MBP which will communicate to Modicon BM85Y422 BridgeMux (Modbus Plus to SY/MAX gateway) across our SY/NET to the other SY/MAX processors?

 

You can use the MARC Omnii-Comm to make a more direct connection. You would configure it to use DF-1 to the ControlLogix and Sy/Max to a Square D NIM. The link to a data sheet is http://www.miille.com/din266-p00.pdf or you can contact me directly at [email protected] if you have further questions.
