1. Download the current driver via the link requested from support@kunbus.com.

2. Extract the package df_profi_II_linux_kmod to your preferred direction.

3. Open a terminal and navigate to the extracted file.

4. Compile the driver to your current Kernel by running make.

5. Load the driver to kernel → sudo insmod dfprpci.ko.

6. Mount Kunbus.iso to your pc.

7. Extract the file Kunbus.iso/DF_PROFI_II/Linux/dfpr_II_pci.rpm to your preferred location.

8. Navigate to the extracted package.

9. Run the script DFPROFI_II-PCI-INSTALL.sh → sudo bash ./DFPROFI_II-PCI-INSTALL.sh.

   1. The Board should be detected like shown in this screenshot.

      

   2. In case the driver will not start by the script, close the script with CTRL+C.

      1. Start the driver manually.

         1. Navigate to /etc/init.d/ and run sudo ./DFPROFI_II start.

         2. Now you should find a file named “dfpr” located in /dev/.

   3. In case the driver denied with “invalid major device number”

      1. please go back to step 4

10. Now the Profibus board should be shown in the response of dmesg (in bolt letters) with the MAJOR-No. displayed in the last line of the previous step.

    

11. In case of using an 64 Bit OS, get the folders loados_x64 and load_x64. Else continue with next step.

    1. opt. delete or rename existing executables in loados_x64 and load_x64.

    2. Compile the code by running the makefiles in both folders.

    3. Make the compiled outputfiles executable by typing for example chmod +x loados in your terminal

    4. Copy the executables loados and load out of this path to your extracted package path. Place it there in /<extracted package>/usr/local/dfprpci/ and replace the existing ones.

12. Navigate to /<extracted package>/usr/local/dfprpci/C_Sample_Program/ and compile the example by running the makefile.

13. Run the example in your terminal with ./DFProfi_2_PCI_DEMO.

    1. Initialize the board by typing I.

    2. Now the os dependencies should be load within “loados”.

    3. The application “load” loads the driver packages to the example application.

    4. A successfull initialization will shown as I Initialize hardware : OK! in our application.
