rslogix5000 communicating with Vacon X5 drive

[matlark]

This is the first time I will be attempting to communicate with a VFD (ethernet). Anybody have any sample programs with a small description of the fields I would need to use within the MSG instruction? I am assuming the MSG instruction is to be used, if not which instruction or combo of instr would be best?
thanks

Why do you think you can communicate to the Vacon X5 drive using Ethernet? While it has an RJ45 connector that is for RS485 - Modbus communication. Read the manual.

Just noticed that while reading manual. Still don't know what ladder instructions would help me communicate with the VFD.

The instructions will totally depend on how you will actually communicate with the drive. The RS485 connection and the use of Modbus are both items not found in the basic Compactlogix or Controllogix system.

Apparently I need to add a pro soft mvi69-mnet to the compactlogix sys.

That Prosoft module provides Modbus/TCP (Modbus over Ethernet). Where would route its output?

I believe you would need the MVI69-MCM module for serial Modbus. it provides for RS485 outputs.

Will be using a prosoft MVI69E MBTCP (AB distributor suggested) Still not sure what ladder commands I need to use to control the Drive, never done anything like this before.

I still don't see how that module helps with connecting to the drive you have specified. But anyway, good luck.
