ActiveX Components for PCI-6251 DAQ Card

[hzxkdh]

I am using ActiveX Components like CWAI... for PCI-6052 DAQ cards and now need to deal with DAQmx cards like the PCI-6251.  I program in Delphi and can use any of the MSVB2005 comonents or similar, if available.  Are these components modifyable or do I need to have our company purchase new ones?  Are there any other solutions than I stated?

Hi Hzxkdh,

From my understanding, you are currently using CWAI activeX controls in Delphi to program your PCI-6052.  You mentioned that you would like to move to the PCI-6251.  There are a few things to consider when upgrading.  6251 is an M-series DAQ device and is only supported with the DAQmx driver.  CWAI activeX controls are the predecessor to Measurement studio and are not supported in DAQmx.  They were created for Traditional NI-DAQ legacy driver which I assume is what you are currently using with your 6052.

Measurement Studio(MS) has replaced CWAI and is compatible with DAQmx.  When you purchase MS you receive the .NET controls and VB6 activeX controls.  National Instruments does not support MS in Delphi.  MS is supported with Visual Studio.  There are customers who have had varying degrees of success using Delphi but this is not supported by NI.

I hope this helps!
