In the link, the word "manor" should be spelled "manner".

No I meant manor like a house...wait. No I didn't. Good catch. I'll fix that on the next iteration of the article.

Quite interested in using MPE but noticed it requires version 8.6 for both LV and LV RT. We are currently on 8.5.1 for both and don't want to upgrade just yet (in the middle of flight testing a large chunk of code right now).

What is the reason(s) MPE will not work with lower than 8.6? Would there be any reasonable workarounds to make it work with 8.5.1? Our targets are PXI (flight hardware) and desktop (development) RT systems.

Thanks,

GWN

It is in 8.6, just because that is the current version I am working in. The only thing that I think would be 8.6 specific is using the conditional terminal of the for loop to do searches, rather than a while loop (I believe that came in 8.6). That and it is based on STM 1.0 instead of 2.0. That's not really a problem, just look out for the "This VI was loaded from XXX instead of YYY" warning.

Are you able to access 8.6 to downgrade the code, or are you asking me to do that?

OK - thanks for your quick reply - much appreciated.

Not completely sure if we're talking about the same thing but I've used what I call For Loops with conditional terminals in 8.5 so that shouldn't be a problem. As for STM, we're on 1.0.32 for now.

So, I'll just download the latest MPE library as it is right now (i.e. compiled for 8.6) and try to make it run on my 8.5 - should be able to make it work.

Thanks,

Well, I was too optimistic. Forgot that I can't use LV 8.5 to open files saved with a higher version (8.6). I guess that's what you meant by "downgrading"...

Anyway, if it's not too much trouble would you mind saving (with "Save for Previous Version", I guess) the MPE library for 8.5, and making it available on this site?

I don't have access to LV 8.6 yet.

Thanks,

GWN

Here is the 8.5 version of MPE. Unzip it to your LV 8.5 user library. It is hard for me to test, so just tell me what else might help you. 🙂

Downloaded and was able to open all VIs with my 8.5 - thank you.

Will try to figure out how to use it all in the next few days, time permitting.

Sure thing. I forgot to downgrade the examples to 8.5. Here they are.

Is this Library Support LabVIEW 2010 Realtime?

I run the Example on Windows perfect.

But when I follow the Step in the guide Running the Example on a Real-Time Target, RT program runs incorrect,

It Seems that RT Server VI cann't find VI build in RTEXE.

Thanks for any help!

Not sure. Haven't tried it in LV 2010. What kind of error are you seeing? Which file does it say it is missing.

it seems that when open RTEXE and list VI in it,an file not found error occoured.

May be I could use souce code distrubition instead the rtexe?

I will get some try on it.
