Hi,
I'm developing a RT-Application at cRIO-9074 target (using LV 2012). I'd like to control a simple engine throgh PID-controller.
Now I found two possible PID vi's:
1. Real-Time -> Function-Blocks -> Control -> PID
2. Control design & Simulation -> PID
What is the difference between both?
Is it possible, that the first PID-Controller might cause problems when it is running a long time (longer than 12 hours)? I placed the sub-VI with the controller into a timed-loop. After more than 12 hours runtime, the timed-loop didn't excecute. The other loops (not timed) for TCP-IP to the Front-panel did work fine...
I don't know if my problem is caused by the PID.
The other possible reason might be the timing source. Are there any known problems with timed loops and sync to scan engine as timing source? Is there maybe a reinitialisation of the scan engine, that causes a problem?
My long-term test was with compiled startup-application, so I can't state more Debug info.
I'm looking forward to your answers
Fabian
