Error -200371 using DAQmx

[everyonesUsedMyAlias]

I can't seem to find any reference to the error code -200371. The error occurs immediately while using the "DAQmx Create Virtual Channel" VI. Any clues as to what the error refers to?

From reading the error description it seems like your in your Create Virtual Channel VI you have specified to use the same physical channel twice. Maybe you are using a global channel which accesses that physical channel as well as specifically using that physical channel in your task? Without more details I can only go with what the error message says and make best guesstimates.

Hi,

You can get definitions of error codes in LabVIEW by going to Help >> Explain Error...

Type in the error number "-200371" and it will tell you:

Error -200371 occurred at an unidentified location

Possible reason(s):

Requested multiple virtual channels that correspond to the same physical channel within a task. A task cannot contain multiple physical channels of a specified type.

Use different physical channels for each virtual channel.

I got the same error message. It happens when generating continous signals from a DAQ device (USB 6361) with a while loop and using virtual channel to set a buffer. The task and virtual channel are outside of the loop, but the task input needs to be the same as the DAQ task out, otherwise it will not generate countinous signals. Attached are the data file and the VI. Please help.
