Repeatedly call a function in App Designer while working with the App

Hi,
I created an app in app designer that has buttons to load, plot, process and analyze data.
How do I implement a function into the app that runs every second while the user can simultaneously work with the app and click on buttons, load data, etc.
I want the app to continously do something regardless of what action the user takes on the app. The app is supposed to communicate with a PLC, read and then send back a signal continuously every second after startup of the app. When the app crashes or is closed the function wont be called anymore.
Thanks.

Hi
Have a look a these:
I can think of roundabouts to avoid using the background pool but they won't do exactly what you want.

Sorry to answer that late,
But yes, with the function parfeval, you can call a function in another pool, while keep running your app as usual.
Let's say the code you want to run can be written as [Y1,Y2] = function calculationBackground(X1,X2,X3), you could call
F = parfeval(@calculationBackground, 2, X1,X2,X3)
and then get the results with
[Y1,Y2] = fetchOutputs(F)
For your application you will need to include the pause inside that background function
