State machines on Real Time

[Ton Plomp]

I'm going to start a Real Time (Crio) project and it's been a while since I've been there. Last time was 5 years ago.

It's an old controller and I am wondering if a how a State Machine will perform on that platform?

Or any other recommandations?

LVRT even on an older cRIO should provide plenty of cpu bandwidth for simple constructs such as a state machine or timed loops etc.

The things that can really eat up cpu is the scan engine and the use of network shared variables. BTW, the distributed system manager

will give you a readout of cpu% and memory usage so you can easily run some preliminary tests.

I built a system on a sbRIO (basically a unpackaged cRIO) earlier this year that used a state machine no problem. Matter of I used a modified version of the JKI state machine for the basis for the code. Not having a front panel meant some of the open close VI code was not needed.

Based on my experiences you should have no issues building a state machine based architecture on an RT system.
