Error Code -10687 AO Buffer Error???

[TimUIUC]

"-10687 bufferInvalidError 

A configuration change has invalidated the acquisition buffer, or an acquisition buffer has not been configured."

Why am I getting this error. I needed a function generator in my VI so I copy and pasted the Benchtop Function Generator example in, and now I am getting this. I will try uploading my VI, it is a state of disarray at the moment but maybe someone can find a problem.

Thanks

Sorry, also you can delete the "Ford" user-defined VI, as I'm sure you'll get another error. It doesn't contain any Analog I/O functions, only VISA GPIB.

Thanks

Sorry to just keep adding and adding, but if I remove the AO One PT VI inside the larger loop, but outside the small case structure (anyone get that?) it works fine. I'm passing those AO VI's a different channel number, why is it affecting my function generator.

Thanks to anyone that can help

I think it's because AO Write One Update does an AO Config each time it's called. Wtih one analog task already running, you do not want to do another config. Instead, place an single AO Config someplace in your program for all analog outputs and just use AO Single Update instead of AO Write One Update
