MAX SEES MY PXI DAQ DEVICES BUT MEASUREMENT STUDIO 6 DOES NOT

[Leamount]

PXI 1042 Chassis System with 8196 processor. Installed - 4 boards - PXI 6733, 6528, 6250, 1428 - MAX sees all devices perfectly - but the 6733, 6528, 6250 do not show up in VB6 measurement studio DAQ tools eg CWAO does not list my PXI 6733 AO module. Loaded development studio 8.0 - and Measurement studio for VB6 version 8 - all licences activated, also the VB6 upgrade and VB6 service pack installed.

Note that the 1428 does appear (camera link card with IMAQ vision) - and other measurement studio features are OK.

Any suggestions appreciated

Thanks chris/leamount

Hi Chris,

The 6528 and 6250 boards are only supported in NI-DAQmx, this means that you wont be able to use the CWDAQ controls in Visual Basic, as these controls only support Traditional NI-DAQ (Legacy). You can use the NI-DAQmx driver in Visual Basic to program these boards. The following link give more information on how to go about this.

For the 6733 this is supported by both NI-DAQmx and Traditional NI-DAQ (Legacy). So you should be able to see the board listed under the CWAO control. Check that you have the Traditional NI-DAQ (Legacy) driver installed, the latest is version 7.4.1 and can be downloaded from the link below, or will be on your driver disks. It may be that you haven't installed this, and where you can see the board in MAX it is listed under NI-DAQmx devices. Once you have installed this driver you can then program this board using either driver/method, but it would be better if you use NI-DAQmx to program all the functions in your application. I've included a link which answers a lot of questions users have when upgrading from Traditional NI-DAQ (Legacy) to NI-DAQmx.

If you have this driver installed already (You can check this in MAX by expanding the 'Software' section of the 'My System' tree), and you still can't see the device, then try shutting MAX down before you open up Visual Basic, as MAX could be holding the board resource and blocking access to Visual Basic.

I hope this information helps, please let me know if you are still having difficulties.

Dear Hanna,

Thankyou for your reply - but it did not really help.

However, after a few beers in the bar and a good nights sleep I dragged back a memory of similar problem from 12 months ago and invoked 'The Magic Palbase.exe'. Running this as instructed cured the problem and my PXI-6733 appeared as if by magic. tra la

When I pay umpteen thousands of pounds for software do I really have to behave in this 'Nerdish' way? This problem has now propagated through several releases of Deveopment Studio and should have been sorted by now. I do not want to be Nerd, I try hard not to be a Nerd, Please try harder.
