Analog Output Timeout on Real Hardware

[jleeman]

Hello all,

I have the following vi that simply reads in a text file of voltages to write out, then writes them out at the requested rate.  This isn't pretty, but it's only to allow us to use an "old style" control file in our system.  This vi seems to run perfectly on my system when I am simulating the hardware, but when I use the vi on our PXI chassis, odd things occur.  The file runs normally for some amount of time, then then voltage stops changing and the vi sits there until it times out with the DAQmx error 200560.  i.e. the wait until done didn't return.  Any ideas on what is going on? This is a new PXI system and we are using a PXI-6733 for the output.

I have attached the vi, and screenshot of the block diagram, and the control file (it is zipped).

Thank you,

John

you have not put your vi inside a loop so your frame will run once (as mentioned in png). i have not seen your vi as there is some ver issue

No, turns out the issue is that the buffer size must be an even number.
