Error -50103 occurred at DAQmx Start Task

Hello,

 

I am running this program with a NI 9472 DO 24V module as a counter for the fan I am controlling using PWM and the relay.  A possible solution I think would be to combine these two loops and create multiple tasks for a single channel.  I believe the error is the result of trying to run two separate tasks on this certain module, but I'm unsure.  I am measuring resistance and temperature on a NI 9219 AI module and that is running fine (part of program not pictured).

 

My problem is that I learned Labview this last summer during my internship, and am back for a week during winter break.  I am quite rusty and troubleshooting is rather troublesome, no pun intended.  

 

Does anyone have ideas/workarounds for this error?  During the summer I messed around with reserving and unreserving tasks, which seemed to partially fix the issue.  After changes and simplification, this error has returned.

Did you search the forums for error 50103?  You'll see this question asked hundreds of times before.  You can't have multiple tasks for a single DAQ device.

 

Make a single task that includes both channels!
