Re : unknown error -201003: (DAQmxCreateAOVoltageChan: return value ==-201003)

Hello,

I am running a digital output module on Labwindows/CVI 2012 (version 12.0.0) and I got the following error (I couldn't any reference for this error status code):

"Function DAQmxCreateAOVoltageChan: (return value ==-201003 [Oxfffceed5])
Device cannot be accessed. Possible causes:
Device is no longer present in the system.
Device is not powered.

[...]"

While running following code:

ErrDAQmxAnalogOutput (DAQmxCreateTask("",&taskDynamicGeneration),30);
ErrDAQmxAnalogOutput (DAQmxCreateAOVoltageChan(taskDynamicGeneration,SignalConfig.chan,"",SignalConfig.min,SignalConfig.max,DAQmx_Val_Volts,NULL),31);

No change occured on hardware while running and this error doesnt always happen (intermittent problem, I don't know why), so that I cannot identify any cause for this error. Could you help?

Thank you

Hello,

Without all your code, it's difficult to determinate the root of the error.
I advise you to run an example of LabWindows/CVI

To find it, check the different screeenshot bellow and tell me if this error appear again.

It worked fine with this example.

It appeared that we actually had an hardware problem on power supply when switching some relays and this error I have logged could be a consequence of it. I solved the power supply problem and did not reproduce this problem. I hope this would be solved so!

Thank you very much for your quick reply and advice!
