-My plan to use PXIe-6363 with PXIe-4300

to do the following task:

1) send digital output from PXIe-6363.

2) read analog input voltage from both cards

-all the task shall be done on the same time.

-Error 89137 appeared.

-How can rectify the error?

To rectify the error you might use ClearError…

The better option is to read the error description and to act upon that message!

Then there is a different problem in your VI. But you decided not to share this VI…

I will share it tomorrow..However, I used two DAQ assistant inside the while loop. The first one to write the digital output for PXIe-6363 and seconds DAQ assistant for reading analog voltage with the same card pxie-6363 and  pxie 4300...

There are typical problems:

  • using DAQAssistent instead of simple DAQmx functions
  • using one task to handle more than one DAQ card

Do you know this one?

Hi Ahmed,

 

please don't use proprietary Office file formats just to attach images. Use PNG files instead!

 

Which task is giving the error? This is not visible from your images…

(I guess you cannot place channels from both cards into one DAQmx task: create a task for each DAQ card.)

It is possible to place the channels from two cards into one DAQmx task. The error attached before describing error sharing the clock. I running digital output task with analog input task and clock will be share between them.

Hi Ahmed,

 

sharing clock between AI and DI on one card probably is possible. But sharing clock between DI and several AI channels on different cards might be problematic...
