are references a good way of data transfer between parallel loops at different rates?

[VeeJay]

To transfer Numeric values back and forth between two parallel loops. I am currently using references. It works fine. What would be the best way considering different rates of while loops. Thanks!

Functional global???

I usually use queues or an Action Engine.  Using references ties things to indicators and the UI thread which may produce a performance reduction.

THanks for the quick response. A simple example of functional global and action engine would be helpful. Like really simple example to get the concept right. Any directions on that?

Correct and correct UNLESS you are talking about a DVR = Data Value Reference.

See here for my Nugget of Action Engines.

They are the same thing. Go to Google and type in "labview functional global" and the first hit should provide an explanation.

@ Ben, I have tried understanding your nugget a few times. It kinda jumps in to the concept directly and I find it hard to correlate it to when I actually have to use it. But, I will give it another shot. Reading n times always helps.

THanks all!

[VeeJay]

Are there any examples out there that have action engines implemented? Theory only does so much to my understanding. 😞

[Ben]

There are examples included with that nugget.

It also looks like I added an Actin Engine to the Tetris Game (post 26?) in this thread.

I attached the most basic example I could think of.
