Programming Counter Timer and High Speed Digital IO Boards in Measurement Studio 7.0 Environment

Hardware: Digital I/O (DIO), Counter/Timers (TIO)

Problem: Since the PCI 6533 is not currently supported in NI-DAQmx, can I program it in Measurement Studio 7.0?

Solution: NI-DAQmx 7.0 does not support the Counter Timer and High Speed Digital IO Boards. However, you can program the cards in traditional mode by using Active X controls or through DLL function calls.

To add the CWDAQ ActiveX Controls to a .NET project, do the following:

  • Inside a .NET project, go to View >> Toolbox.
  • The Toolbox will appear. Right-Click in the toolbox and go to Add/Remove Items.
  • The Customize toolbox will appear. Select the COM Components tab.
  • On this tab, you can select the specific CWDAQ control you wish to use and click OK.
  • The control you selected will now show up in the toolbox, where you may select it and drop it onto the form.


    Note: It is recommended that you use Active X controls. The .NET environment does not include native support for DLLs. As a result calling DLL functions in .NET is complex and you have to include the function declarations at top of your source code.
