Create array in a VFG

[GSXR100038]

Hello,

I would like to know how to create a array into VFG optimally. I know how to do but I don't think I have the right method. Do you have an example Do you have any examples that I can use as inspiration ?

Thank you for your helps

Regards

Just for my curiosity: what does VFG mean?

Some possible acronyms:

Victorian Frog Group

Vista Financial Group

Virtual Facility Group

Versuchsanstalt Für Getreideverarbeitung

Very fast-growing

Visual Flight Guide

Virtual Fighter Group

Voice Frequency Generator

Valley Fig Growers

Virtual Facility Groups

Virtual Focus Groups

My bet is however on:

Variable Frequency Generator

But even if I'm right I would have no ideas what the OP wants exactly. It depends a lot on the type, make and model of such an instrument, to know what would need to be done.

Sorry,

VFG it's in French, I think it's FGV in english (Function Variable Fonctional).

Maybe a Functional Global Variable?

Show us how you currently do it (whatever it is!) and if there is a better way, we will tell you.

What's wrong with your current way (performance? convoluted code? incorrect result? does not always work? something else?)

Sorry, of course yes that's it.

Hi,

Thank you,  Finally I managed to do something. I don't know if it's correct but it works for me (see in this attached). I use to synchronize 2 loops which do not have the same sampling frequency.

• You did not include the typedef, so I had to disconnect it
• Since the stored array is always size=3, you can wire the "Value_in" directly to the replace array subset. No need to index and build a new array. The array will always be size=3, no matter the array size of "Value_in".
• If Value_in is guaranteed to be size=3, you don't even need the "replace array subset".
• You don't need to wire the index=0 for the replace array subset, it's the default.
• I would recommend a feedback node because you can globally initialize it and also eliminate the while loop. This will guarantee that the size is 3 and all zeroes on first call, even if you forget to initialize. (In your code: If you write before init, the array will be size=0 on first run. You cannot replace elements that are not there.
• I would make the "read" state the default, so you typically don't even need to wire it when reading.
• Most of your output tunnels can be configured to use default if unwired, eliminating all these stray zero constants.
• Not sure why your VI has an icon that depicts a matrix. Not intuitive and confusing!

It could look similar to the following:

Thank you, let me a little time to watch please, after I'll be back.
