KUNBUS Configurator III

Issue Details

I want to configure and set up PROFINET communication using NI PXI PROFINET Interface Module with KUNBUS Configurator III application. I installed PROFINET for PXI drivers onto the Windows 7 controller. However, the KUNBUS Configurator III application is not loading. 


KUNBUS Configurator III is officially supported on Windows 7 OS, however, with the current software versions not all states of Windows 7 lifetime would work with Configurator III as Configurator III application has many dependencies on Windows OS.
It is recommended to upgrade to Windows 10 OS for the KUNBUS Configurator III to load properly.

Additional Information

KUNBUS Configurator III has many dependencies on Windows. Since Windows 7 & many other applications are not supported and updated anymore, this could be the reason because of which Configurator III is not working as expected. However, the LabVIEW project & drivers of Kunbus Software are not affected and are stable. PROFINET Drivers depend on the NI Software platform & are not affected by different versions of Windows OS.
Here are some troubleshooting steps:
  • Verify the PXI PROFINET module is showing up in NI MAX correctly.
  • In Device Manager, under NI-VISA PXI Devices, check if the DF PROFINET IO (NI-VISA) is visible.
Device Manager
  • By navigating to LabVIEW Help>>Find Examples>>Toolkits and Modules>>Third Party Add-ons>>KUNBUS GmbH>>PROFINET, DF PROFINET IO GettingStarted.lvproj LabVIEW project and running the sample VIs, check the device communication is established or not.
