MODBUS Library for LabVIEW

Issue Details

I just added a new library to LabVIEW, following all the instructions and copied all necessary files to the corresponding directories. However, I cannot find the corresponding VIs in the User Libraries palette in the Functions palette. They simply are not there. How can I add these VIs successfully and use them?

Solution

This could be happening because the library is being copied to the wrong directory. Normally there are two National Instruments directories in the hard drive (C:), one in Program Files and one in Program Files (x86). In the first one you will find files corresponding to 64-bit software and in the second one you will find files related to 32-bit software.
  • If you are using LabVIEW 32-bit, make sure to copy the library to the folders in the National Instruments directory located in the Program Files (x86) directory.
  • If you are using LabVIEW 64-bit you must copy the library to the folders in the National Instruments directory located in the Program Files directory.
