DAQ Assistant can not see my devices

[K VD]

I have a PXI chassis with an 8196 Embedded Controller (RT ETS) and two PCI-7833R boards. My laptop is running LabView 8.01, MAX 4.03, NI-RO 2.0, NI-DAQ 8.1. LabView RT

When using the DAQ Assistant to set up virtual channels and tasks there is an error message "No Supported Devices Found".

What is the problem?

Thanks,

Ken

Hello Ken,

You have to repair the LabVIEW installed on your computer....just insert ur LV CD and go to control panel(if using MS OS) and go to National Instruments program in the list and press Change there u will see reapir option just click on that and provide the path of the CD inserted into ur Cd ROM.....simple

Hi Ken,

The problem is you have no supported devices, let me explain. You are trying to use the DAQ Assistant to address an R-series device (FPGA) not a DAQ device (E/S/M-Series, CounterTimer, etc.)

While you can use the DAQ Assitant under RT, I would not do so, but this is getting off topic.
Back to your problem with the 7833R, I am assuming you are using the PXI version not the PCI version as stated.

1) On you laptop open LabVIEW 8 and start a New Project
2) Right Click on Project: Untitled and select New >> Targets & Devices
3) Choose FPGA device and find the 7833 you want to add, then click OK
4) You should now have an FPGA target in your project you can access and develop code for.
Repeat steps 2 - 4 to add the second FPGA device.

Yes, it is PXI, not PCI.

I still do not understand why this is not possible. I would like to use some of the boards analog inputs and outputs directly in my VI running on the 8196 controller. I seem to remember someone demonstrating this to me using the DAQ assistant.

I have tried to repair the LabView installation but still no luck.

Please help..

Thanks,

Ken

Hi Ken,

In the demonstration a DAQ card must have been used, as this is all the DAQ assistant can address.
You can use the FPGA board for Analog In/Out, but you have to program the FPGA board, using the LabVIEW FPGA module.

If you just want to use the DAQ Assistant, then you will need a board such as the PXI-6229 or the PXI-6259, these have 32 AI and 4 AO channels, they can be addressed by the DAQ Assistant on a real-time target.

Hi Ken,

As James mentioned, the DAQ Assistant is for NI-DAQmx compliant devices only and any FPGA device uses the NI-RIO driver and not DAQmx. If you were demonstrated the DAQ Assistant then this must have been with a DAQ device and not a RIO device.

I'd go to Help>>Find Examples and take a look at the RIO examples that are supplied with thedriver install.

Thanks,

Stuart

Ken,

Just to add please check out the Getting Started With LabVIEW FPGA KB document.
