Error 200479

[Batasel]

Hi, 

I have created a timer for the data acquisition vi of and I'm getting the error 200479 when the timer ends and finishes running the program. 

MY END goal is to create a timer for the below attached block diagram, such that the program will stop running in 60 seconds. Can someone please help me to set up a timer to a DAQmx system. 

Thank you,

Put indicators or probes on the error wire INSIDE the while loop.  Where is the error occurring?  My guess is that it is happening on the analog output lines because it seems you are continually writing new data to a continuous acquisition and trying to start the task on every iteration of the while loop.
