I was wondering if anybody could give some advice on how to connect Labview to a Modicon Quantum PLC ( the card is 140 CPU 311 10). I am wanting to use Labview as an HMI to control the PLC which is being used to implement PID control with a VFD. Currently I can communicate through Modbus to the PLC for programming using UnityPro XL, but I have no idea how to connect Labview. I have read the section on NI site "connecting Labview to any PLC through Modbus" but i am still not sure. Any help will be greatly appreciated.
