cRIO Memory management

[VE_KVK]

Hi,

I'm using cRIO9014 with LV 8.2.1. My application involves logging data from a device thro RS232 and save it to cRIO memory. What will happen if the memory (2GB) overflows? How to make the oldest data replaced with newest data?

Pl help.

Thanks

I suspect when your memory overflows, you will get some pretty strange behavior, or your application will crash altogether.

You could use a circular buffer to replace the oldest data with the newest. There's plenty of information about these (and a version to download) on NI's website.

Definitely should crash. At least that is what it does to me all the time.

If you want too log your memory usage here is where their are VIs to do it. In LV2009 they are native.

Thanks for your inputs. I wasn't aware of the circular buffer concept. Will try.
