Modbus Programming Examples

A newer library, intended as a replacement for this one, was added to this page. This is not an official NI Product.

Version 1.2 (ni_modbus_1_2.zip) of the MODBUS LabVIEW Library is backward compatible with previous versions of the library. It adds a set of polymorphic VIs that make it easier to use MODBUS commands. These new VIs are also fully documented with a help file. Comments have also been added to the examples. Please follow the steps in the readme file for manual installation of the library. There is no installer available at this time.

This library is not designed for use on LabVIEW Real-Time run-time's and will not execute deterministically. Use the Modbus API available through the LabVIEW Real-Time Module or the LabVIEW Datalogging and Supervisory Control (DSC) Module instead.
