Accessing PCI-6220 under Agilent VEE

[UliK]

Hi all,

I am trying to access a PCI-6220 DAQ M-series board under Agilent VEE Version 7.5

Since the M-series boards are not supported by the traditional DAQ driver (NIDAQ32.DLL) it can not be done the usual way?

Does anybody has an idea whether there is a DLL I could use or another way how to do it?

Thank you,

UliK

Hi,

National Instrument give support for Software, where we can test our Drivers. This is why I had copied a part from the Readme. There you can see the supported Application Softwares.

I searched our WebSite for a dll for DAQmx, like the one you mentioned for traditional DAQ but I didn´t find anything that helps.

If I where you!? Next Step: "I would ask Agilent."

 

Copy from the NI-DAQmx 8.0 ReadMe

NI Application Software Support

The following table lists the NI application software versions supported by NI-DAQmx and Traditional NI-DAQ (Legacy). If you are not using NI application software, refer to Microsoft Visual Studio Support.

NI Application Software	Versions Supported by NI-DAQmx	Versions Supported by Traditional NI-DAQ (Legacy)
LabVIEW	7.0 and later	7.0 and later
LabVIEW Real-Time Module	7.1 1 and later	7.0 and later
LabWindows/CVI	7.x and later	6.0—7.x
Measurement Studio	7.x and later	6.0—7.x2
1 To use LabVIEW Real-Time Module 7.1 with NI-DAQmx, you must use NI-DAQmx 7.2 or later.
2Traditional NI-DAQ (Legacy) does not include a Measurement Studio C++ or .NET interface.

Microsoft Visual Studio Support

The following table lists the programming languages and Microsoft Visual Studio versions supported by NI-DAQmx and Traditional NI-DAQ (Legacy).

Programming Language	Visual Studio Versions Supported by NI-DAQmx	Visual Studio Versions Supported by Traditional NI-DAQ (Legacy)
ANSI C	6.0 and later	6.0 and later
C++	2003 (7.1)1	—
Visual Basic 6.0	6.0 SP62	6.0 SP63
.NET Framework 1.1 Languages (C# and Visual Basic.NET)	2003 (7.1)	—
1 Requires Measurement Studio 7.x
2 Support through ANSI C type library
3 Support through ActiveX

This seems like a question that should be addressed to Agilent.

Hi All-

The NI-DAQmx .dll for the C API is "nicaiu.dll" .  A discussison of the C API installs with the driver at Start>>Programs>>National Instruments>>NI-DAQ>>NI-DAQmx C Reference Help.

As for instructions on how to call the ANSI C functions within, I agree that a call to Agilent for their advice is in order.  As Alex R mentioned, Agilent VEE is not supported directly so this method is untested and not officially supported. 

Hopefully this helps-

Never actually trying this I am just guessing.  I think you could try compiling one of the ANSI C examples into a dll.  As long as you had DAQ installed and allowed the user to pass in the DeviceName/physical channel I see no reason why that wouldn't work ( I am assuming VEE allows you to call dlls).  But, as I guess you have gathered this has never actually been tested.

Dear All,


I got the NI-m-series board running using the C DLL finally. I attach an example VEE program
(Vers.7.5) and the header file to this mail.


In short:
- I used the compiled library nicaiu.dll in folder ...\windows\system32
- to make things simply I used the NIMax to define a NIDAQmx-task interactively (voltage range, sampling frequency etc. but you may use the corresponding functions in the dll as well... (the task I called MyVoltageTask)
- I modified the header file nidaqmx_vee.h. Here the thing which did not work first was the passing of the taskhandle. In the functions DAQmxCreateTask and DAQmxLoadTask it has to be defined as long *taskHandle in all other functions as long taskHandle!


If anybody needs more info, please let me know,

Hi Uli,

ist es vielleicht möglich wenn du diesen Eintrag liest, dass du dich eventuell mit mir in Verbindung setzen könntest, da ich wie du ein M Serire DAQ Device mit VEE ansprechen möchte und noch diverse Fragen dembezüglich habe.

Vielen Dank

Hi everyone!

I baught NI PCI-6511/13 Digital IO cards with NIDAQmx support.

I want to use Agilent VEE 7.5 that does not support NIDAQmx right now.

I saw all options (i hope) how to work with NIDAQmx in Agilent :

1. Use C API calls ( check registered classes : NI DAQmx C API in ActiveX and .NET ) - but problems with data types ???

2. Use C API calls ( import nicaiu.dll + rewrited header file for Agilent data types)

3. dotNET support : NationalInstruments.DAQmx.dll --------> with this option i have a problem for trying to use.

    After all installs : NIDAQmx 8.0 ; even Visual Studio .net 2003 there is no class in .NET list

    called NationalInstruments.DAQmx !

This is an example from Agilent forum (?) for .Net usage i guess (?) i attached .

Here i saw this class name NationalInstruments.DAQmx in .NET list .

NationalInstruments.DAQmx.dll is in National Measument Studio dotNet folder

But i did not find it in C:\Windows\System32\   folder !!!

There is no registration of this dll. National supports .net languages ; so i want to use

NIDAQmx dotNET support in any program - not only VS 2003 !

Is there solution at all?

Hi!

Look at my repaired example

This works fine with NI6513

i modified " *reserved " to "reserved" and there is no problem with "NULL" byRef value.

Hi,

I'm currently using VEE 7.5 and trying to take data using NI's DAQPad 6015.  Though I found the post for the PCI-651X under VEE very helpful, I'm still having problems with my code.  I'm using the posted "nidaqmx_vee.h" and the "nicaiu.dll."  I would like to acquire data from a channel until I tell it to stop.  Does anyone know how to fix my code to make this work?

Thanks,

Darren
