Issue Details

We intend to integrate some Modbus Devices with LabVIEW 2014. Can you please let me know if we get the drivers with LabVIEW or is it a separate package?

Solution

Modbus is a commonly used protocol for industrial communication. At present, National Instruments provides these options for Modbus connectivity:
1) Modbus I/O server, available through the LabVIEW Real-Time Module or the LabVIEW Datalogging and Supervisory Control (DSC) Module which provides a high-level API for accessing Modbus data.
2) A free Modbus lLbrary available for download which is very low-level, and provides control over Modbus not offered by I/O servers at the expense of the connection management and request scripting offered by that higher-level API. However this Library being a third party example program, is not officially supported by National Instruments.

The Modbus API available through the LabVIEW Real-Time Module or the LabVIEW Datalogging and Supervisory Control (DSC) Module. This is a version of the NI Labs Modbus API which is now supported and maintained by National Instruments R&D.
