Issue Details

I was using the LabVIEW Modbus API with the LabVIEW Real-Time Module. Suddenly, my Modbus palette has disappeared. How can I fix this?

Solution

When using the Modbus API from the LabVIEW Real-Time Module, the Modbus palette will only appear in VIs that are under a Real-Time target in your LabVIEW project. Try simulating a Real-Time target and creating a VI there to see if the palette appears.

You can then move the VI back under the My Computer target.
