storage an array with data

[Talo]

goal: storage an array with all the data.

I try to do one program and I need storage in one different place the data that I obtain call a sensor temperature. e.g: I call my program and I obtain one data, then I call my program again and I need storage the data in the same array but in other place.

How could I make this?

How can I create an array that storage all the data in the differents call to my program? Could be with one global variable?

How can I storage the data in different place of this array? Because I'm trying to do it and I'm be able to storage only in the first part of the array and this means that each time that I storage data I remove the all data and this is not that I need.

Thanks a lot

You would probably be best off using a "Functional Global" rather than a regular LabVIEW global.

A Functional Global is just a subVI with a while loop that has a shift register and a Case structure in the loop. Your data is stored in the shift register and the Case structure contains any number of states to manipulate the stored data.

I've attached a very simple example that can initialize your data, read, write and one case that can insert data anywhere in an array.

The advantage of using this over a regular global is better memory handling and it avoids the possibilities of race conditions that you must consider for regular globals. Also, since it's just a VI, you can add any number of cases to do whatever you need it to do.

As long as you do not make this VI re-entrant, anywhere you use it will be working on the same data set.
