Diode curve tracer error: specified operation cannot be performed when there are no devices in the task

[RaymondDynamics]

I try to run this Diode Curve Tracer with a mydaq in Labview 2013: https://decibel.ni.com/content/docs/DOC-20392

But I got this error saying "Specified operation cannot be performed when there are no devices in the task" How do I fix this?

[mikeporter]

Umm... By adding a device to the task?

How is the task configured? What does the code look like?

What do you mean by "adding a device to the task"?  How do I do that? The mydaq is connect and recognized by the computer. The .vi supposed to simply read out the data from the mydaq. What the code looks like? Did you even see the attachment in the original question? That is the .vi file with the code.

What do you see if you open the configuration panels  of the two DAQ assistants? (Sorry, I don't have any drivers installed, so I cannot check myself).

Does the MyDAQ work otherwise, e.g. with the test panels?

[RaymondDynamics]

MyDAQ does work properly with other .vi files.

Which configuration panels are you refering to? Those ones?

[mikeporter]

Apparently the way they are using DAQ in that code is to define an acquisition task in MAX and then simply call that task from LabVIEW.

Btw. the MyDAQ does get recognized in MAX. But do you know how to fix the error? 

[Dennis_Knutson]

In the DAQ Assistant, click on 'Run' and see if you get the error. Click on 'Show Details' and make sure the device name is the same as what is listed in MAX.

To solve the error go into NI my DAQ and name the my DAQ to Dev1 and the code will run correctly.
