MATLAB: Do I receive an error while trying to initialize the target board in xPC Target 4.1 (R2009a)

Simulink Real-Time

I have a target PC with PCI-DAC 6703 board. I ran XPCTEST on my host PC and was successful. I opened my model and tried to build it. However, the process failed with the following error message on the target PC screen.

 System: download started...
 System: download finished
 System: initializing application...
 Error: No CB PCI-DAC6703 at bus 0 slot-1.

Best Answer

This error message is typically observed when the board is not connected to the correct bus. In order to get the correct bus and slot numbers, execute the following command at the MATLAB command prompt.

getxpcpci('all')

Once you have the bus and slot numbers from the above command, enter them using the format [BusNumber, SlotNumber] in the dialog parameter "PCI slot" of the driver block corresponding to board.

From the error message, it is appearent that the Scramnet Board is not placed in bus 0 and slot 4. To resolve the error, place the Scramnet Board in bus 0 and slot number 4.

Alternatively, you can identify the slot in which the board is located and accordingly modify the information in the driver block corresponding to SCRAMNET board inside the Simulink model.

To identify the bus and the slot number in which the board is located, execute the following command on the MATLAB prompt:

getxpcpci('all')

From the output information, identify the bus and slot in which the Scramnet Board is placed. Then, enter that bus number and the PCI slot number using the format [BusNumber, SlotNumber] in the dialog parameter "PCI slot" of the driver block corresponding to SCRAMNET board.

Please ensure the "PCI bus" and "PCI slot" fields within the XPCETHERCATINIT block is specified correctly, i.e., matches with the actual hardware setup. Entering the incorrect values for these two fields can result in the above set of errors.

If the "PCI bus" and "PCI slot" fields in the XPCETHERCATINIT block is specified correctly and the issue persists, please check that the network card works.
