Solution
For a new installation that where you have never seen the functions palette, follow the steps below:
- Since the Datalogging and Supervisory Control Module is only supported in 32-bit LabVIEW, ensure that you are using 32-bit and not 64-bit LabVIEW.
- Additionally, ensure that you have followed the steps listed in the Missing Icons on LabVIEW Functions or Controls Palette article.
- Run a Repair of the Datalogging and Supervisory Control Module from NI Package Manager
If you had been using the Modbus API from the LabVIEW Real-Time Module, and are now not able to see it in your palette:
It should be noted that 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.
