Reading from two different instruments - Error -201426

[rodwatt]

Hi,

Sorry, I know this topic has been covered before in the forum, but I have tried the suggested solutions and cant get it to work.

I have PXIe chassis with two cards, a PXI-6225 DAQ (in my code, dev6) and a PXIe-4353 (in my code therm). Ideally I would like to read a voltage from the DAQ and a temperature from the thermocouple. I am having problems reading the two of these at the same time.

If I set my code to use "dev6" or "therm" for both readings (although the returned values are nonsense), the code runs fine. But when I try to read a voltage from dev6 and a temperature from therm, I get the error, "Error -201426 occurred at DAQmx Start Task.vi:7220001".

 I would appreciate your thoughts,

Regards,
Rod

Can you post a snippet of your code (Edit->Create VI Snippet) for those of us that don't have 2017 yet?

Code Snippit attached, also the code saved to vs 16

Separate the tasks with each having their own Start Task VI.  Looks like one of the devices doesn't support a task that has multiple devices.

Thank you for the suggestion. I had previously split them and this worked fine, I was just hoping there was an alternative. Thanks for your input
