Hi,
LabVIEW shows me this error code when I run a Data Acquisition Program. Every time the result is the same for me. I didn’t find a solution for this yet. Can anyone help me please to fix this program error ? Why I have it ?
Thank you !
Error – 200220 occurred at DAQmx Create Channel (AI-Voltage-Vasic).vi:3
Possible reason(s):
Measurements: Device identifier is invalid.
Device Specified: Dev6
Task Name: _unnamedTask
Lab view error creating daqmx channel
You have mixed up the things. Anyway to fix the error do the following steps.
-
Check if you have selected Dev2Â in labview.
-
Change your alias of your USB… in Max to Dev 2.
-
Or select Dev 1 in labview.
-
Check the path also that you are providing.
-
In this way you can got best result.
You can solve the problem in another way also.
-
 Open up the block diagram in your Labview.
-
Double click one of the "myDAQ" blocks.
-
MyDAQÂ wizard will be opened.
-
Go to "Channel settings" click the green arrow.
-
In "Current Physical Channels" find out "MyDAQÂ /aio" Â type list.
-
What is seen in the left side of forward slash, is "device identifier"
-
Now here you can change "myDAQ" identifier that match your "MyDAQ"
-
Now your problem will be solved regarding identifier.
