usb-6221 error

[Højvælde]

Hi

System: Windows XP Pro sp 3

Display 12 Basic Updated to 12.00.01

Board: USB-6221

NADAQmx 9.7.0

I have enablet the NI-DAQmx (no CAN ) driver in the Configurator.

I start Dasylab up and want to place an analog (or other) input / output
I try this I get an error message in the middle of the screen with this text:
"" ""
Driver: Task DA00, Version 12.0

Possible Reason
=> No usable NI-DAQmx tasks avaibel

File: Modul_AD.C lin 618
"" "

What am I doing wrong?

Regards

Benny

Hi Benny,

You need to open the NI Measurement and Automation Explorer (MAX) to create some tasks for your application.

Unlike LabVIEW, DASYLab needs the task created in MAX prior to opening DASYLab.

The task determines the device, the channels, the channel configuration, optionally scaling and other sensor specific settings, and the measurement sample rate and the samples to read (DASYLab Block Size).

I hope this helps. It does say it in the Help->NI-DAQmx Help.

Hi CJ

Yes it solved the problem with the analog signals, but at digital IO is not possible to create a task.

I got a errormessage concerning buffert and non-buffert lines.

It seems that USB-6221 is not compatible with Dasylab if you are using Digitale signales.?

Hi Benny

Is your problem to create the digital task in NI MAX or do you have problems importing the digital task in DasyLab?

If it is the first it might be due to trying to setup options which this module does not support, could you please send a screenshot of the configuration you try to use?

It should be possible to create a Digital Input or Output task in MAX - if it has a problem with buffered I/O, just use the one sample on demand setting.
