Labview real-time limits

[stu22]

Hi, recently i relized that my compact fieldpoint module has realtime on it. Currently ive written my program to use the regular fieldpoint i/o's and read vi's. My question is, if i modify my labview code to use a realtime target, will it fit on the rt module?? The labview program is quite large and uses a good bit of ram, when in use. I Just want to know the limitations of realtime and is it suitable for all applications. No matter how large or what its controlling.

A quick and dirty LV app will run on the RT target provided all of the required resources are available (NO DB if no DB toolkits etc).

But if the app has to run forever then you have to look at the momory useage becuase a RT app requires physical memory and if the app bumps it memory useage up and down expecting virtual memory to kick-in, then the app is not a good candidate for the FP target,,, unless you don't mind it crashing periodically.

RT apps should establish their memory useage when they start and remain steady from there on.
