Solution
The issue is presented when specifying an FPGA I/O In in the VI, is not a valid resource in the LabVIEW Project, as shown below.
- When creating a constant to specify the FPGA I/O item, verify that the name of the resource is the correct.
- Use a control to have the name of the FPGA Resource name options, automatically.

- Drag and drop the I/O item from the LabVIEW Project Explorer Window to avoid typing errors.
