Error in my VI

[Zhenhua]

I wrote a VI to monitor temperature signal for our Cryogenic Temperature Controller (Model  32). But an error usually occurred when my VI is running. Could anybody help me to solve the problem?

Thanks!

What is the error? Please provide a code and which VI is generating it.

We don't have a "Cryogenic Temperature Controller (Model  32)" so we can't run your VI.

Sorry, I forgot to attach the picture

Well, your graph indicates that you were getting data up to a certain point. This means the drivers seem to be working. Could be a timing problem. Have you tried slowing down the acquisition rate?

I would also suggest that you place the init and close functions outside your loop. There is no point in doing these each iteration.

Good point, Dennis. Can't believe I missed that, and it's usually one of the first things I spot. Just got into work. Must still be asleep.

Thanks for your help. I've changed the baud rate, now everything works fine:)
