hi thr all PLC ppl

i have a controllogix hot standby system,and there are FLEX I/O's on controlNET using 1794-ACNR's

there are some 4-5 racks



i want to communicate this system to a DCS over MODBUS,with the CLX system acting as slave and the DCS acting as MASTER,

i have idea that (maybe) the 1794-MVI module can be used to accomplish this task,but i dont know anything beyond that.

can anybody guide me more in this topic,as to how to start off with this
also it will be very helpful if anybody provides me some sample code or gives me links to some sample code

waiting eagerly for reply

thanks in advance

The MVI module is C programmable so it will do whatever you program it to do.

You can use the 1756-EWEB module to provide a Modbus TCP server:

or purchase a Prosoft MVI56-MBP to provide Modbus+ connectivity:
