Issue Details

I have installed the Datalogging and Supervisory Control (DSC) Module for LabVIEW and I am now trying to add an I/O Server. When I right-click my library and select New I/O Server, Modbus is not listed in the selection window. How can I add support for Modbus I/O Servers to LabVIEW?

Solution

Modbus support is installed by default with the DSC module for LabVIEW 8.2 and later. However, this support is an optional feature in prior versions of the DSC Module. 

If Modbus does not show up as an option to add in your I/O Server selection window, you can simply repair your installation of the DSC Module. Be sure to include the option for Modbus support when doing this repair. After this step, you can then add a Modbus I/O Server to your LabVIEW library.

If the issue continues, or if multiple I/O Servers are not listed, it may be that the NI Configuration Manager Service is not running. Refer to this document for more information on fixing this issue.
