Controlling a VFD using Modbus/TCP or Ethernet/IP using LabView?

It looks stretched, but now it is showing.  Play with the width and height that is in the HTML.

Hey nagham777!

 

This post is over a year old, for the best chance at visibility, I'd recommend creating a new forum post with more information. I'd also recommend creating it in the Instrument Control forum. Best of luck!

@pRoF1T Were you ever able to resolve this issue? I have an identical setup and am running into similar issues. I can see the device on the network, I can log into it via a browser and adjust settings but I cannot establish a connection to it using the ABB Drive Composer application or via LabVIEW. Any pointers much appreciated!
