Just heard from someone that Rockwell has come out with a Controllogix processor with a built in Modbus port.
Anyone else knows of this? If yes, can I have the part number please.

What Rockwell has done is developed logic to emulate Modbus out of the Logix serial port

Logix Firmware ver 13.xx has Modbus Support over serial port.
They have a sample program installed in you samples folder for ver 13.

Thanks for the replies.

I know that the MVI56-MCM module from Prosoft has a register space of 5000 registers.

Is there any limit on the amount of data that can be transferred using the Modbus functionality of the ControlLogix with firmware ver. 13.xx?
