I'm running an AutoDAQ.vi program on labview for thermcouples. I'm using an NI DAQ system, when I open the AutoDAQ.vi it's missing an entire display of thermalcouple channels, graphs and calibration to select the type of thermocouple, this whole area is just grey/blank. When I try to toggle the Data Aquisition to On, an error 200477 comes up stating "error occured at the Property Node DAQmx Timing (arg 1) in DAQmx Timing (Sample Clock).vi:1->AutoDAQ.vi" and then "Possible reason(s):
Specified operation cannot be performed when there are no devices in the task.
Task Name: _unnamedTask<2>"
Any help with this? Thanks!! I was thinking since I have a few versions/years of Labview installed this might be affecting this.

Can you send a snippet of the block diagram? It sounds like youre missing functions and you may not have the DAQ drivers installed for that version of labview.

Hi Matt,
Thanks! Yes below is one picture of the bad display, how it's showing up now. And the other is how it should look.

The snippets are of the front panel, helpful but not as helpful as the block diagram. Can you prodive the code or at least a snippet of the block diagram? Is this an executable file?
[Edit]: What is the difference between the snippets as well? Are they different labview versions or ran on different computers?

Hi Matt,
This is a .vi file, called AutoDAQ.vi. I'm not sure how to get to the block diagram since this file was sent to me (I didn't generate the code myself).
The difference betweent the two snip-its: One of them is how it is currently displaying (the "bad one") where there is just a big blank spot instead of thermocouple data. The second is how it should be dispalying (the "good one") and this good one was done on a previous computer someone had set up for me, but that computer is no longer operational so I'm trying to set it up on a new computer now.

Hi Matt,
I'm using an NI 9213 DAQ card. You're right, it is an executable file, just still says .vi on the display screen. I looked up the MAX download, does that just simulate having an DAQ card to determine if it's a problem with the DAQ or not?

Is the application a .vi or .exe extension first? Also i had a suspicion that you might be on a new computer. I would assume UDKA is correct that the device is not connected. Installing NI MAX on your computer should install the drivers you need for daq functions plus you can test your device to make sure it is working.

NI MAX is used for several daq functions, but most importantly for you it gives you the ability to connect and test your device, plus it has many of the drivers required for your device. I have that exact thermocouple module actually. What chassis is it in?
