National Instruments FAQ

What are the differences when running LabVIEW code as a VI or as an EXE file?

• If you create an EXE from LabVIEW code, this is generally not within the scope of support.

• Please contact the NI support for this purpose

• Finally the non-EXE examples provided by KUNBUS will work

• A last idea to get to the EXE after all is to build the KUNBUS code as an EXE.

• If this does not work either, it is a case for NI support, because then there is a general problem.

I would like to use LabVIEW in an older version. Are the drivers compatible?

• We have tested our drivers down to LabVIEW 2014.

I am getting an error “Please install the DF PROFI II-Firmware file… “ what can I do?

Open

Error 7

The error shown in the screenshot below depends not on our project.

It says LabVIEW has an issue with the application located in c:\[…]. Please contact the administrator or developer of that project located there, to get support and verify which files are lost and causing (Error 7).

 Please follow next steps (if new installed jump to 5):

1. uninstall the Kunbus DF PROFI II driver

2. uninstall Configurator III

3. navigate to following pathes if they still exists and verify that the are empty:

   1. C:\Program Files (x86)\National Instruments\LabVIEW 2019\examples\exbins\

   2. C:\Program Files (x86)\National Instruments\LabVIEW 2019\examples\KUNBUS GmbH\DF PROFI II

   3. C:\Program Files (x86)\National Instruments\LabVIEW 2019\help\KUNBUS GmbH\DF PROFI II

   4. C:\Program Files (x86)\National Instruments\LabVIEW 2019\menus\Categories\Industrial Communications\KUNBUS GmbH

   5. C:\Program Files (x86)\National Instruments\LabVIEW 2019\vi.lib\KUNBUS GmbH\DF PROFI II

   6. C:\Users\Public\Documents\KUNBUS GmbH\DF PROFI II\

   7. C:\Users\Public\Documents\KUNBUS GmbH\DF PROFI II\Firmware

4. If the upper points are done, reinstall the DF Profi II driver (v3.0.0) by executing the setup we had deliver you on 23.06.2021. The current Configurator III version will be installed automatically.

5. Please run the DF Profi II LabVIEW example project:

   1. open LabVIEW 2019 (32-Bit)

   2. go to Help → Find examples…

   3. navigate to toolkits and modules… → third party packages → KUNBUS GmbH → PROFIBUS

   4. start DF PROFI II Getting Started.lvproj by double clicking it

   5. execute the DF PROFI II Getting Started Master.vi by following the GettingStarted Manual

6. Please inform us if you could reach the board by executing our application

I am using LabVIEW 2009 and Windows recognizes properly the board but not NI MAX. What can I do?

• Our current drivers supports Windows 10 with LabVIEW 2018 and higher.

• Your LabVIEW version is unfortunately not supported.

Does the DF Profinet CPCI for LabVIEW RT support both the Pharlap and Linux RT operating systems?

Yes our new drivers and board are equipped and compatible with both operating systems:

• Pharlap until 2021

• Linux-RT

It is only the commissioning that differs.

Where can I download software and drivers for LabVIEW?

This is the official download page for NI cRIO dependent software and drivers:

• https://www.vipm.io/search/?q=kunbus

Which driver interfaces are supported by the Industrial PC interface boards?

• DF PROFI II

  • https://www.kunbus.com/pc-cards-profibus-df-profi-ii.html

• DF PROFINET IO

  • https://www.kunbus.com/pc-cards-profinet-io.html

Are the KUNBUS PC boards accessible with higher level languages (e.g. C#, Python, Java etc.)?

We ship our boards with a C/C++-driver and example project. Almost all high-level languages offers interfaces to C/C++.
So feel free to wrap our provided functions in the example, with your preferred high-level language, to meet your requirements.

Can I transfer data with 1ms cycle time?

Yes, it is possible. You have to reduce the data to 64 Bytes.

Does the cRIO PNAD support the S2 system redundancy for connection to H-controllers?

No, this feature is not supported.
