Application Loop Shutdown Synchronization

[10Degree]

Overview

Coding that exemplifies how to perform a synchronized shutdown for loops in parallel.

Description

There are many times where I write an application that contains two or more loops running in parallel. To synchronize shutdown of these loops in the past, I have wired an execution flow enforcing wire from the loop to my main application finalization code. With several loops, this can become messy on the block diagram. I came up with a method that uses Rendezvous vi’s to synchronize this shutdown in a cleaner manner. The attached code is an application framework or “shell” that I use for many applications that require multiple loops executing in parallel. The attached VI does nearly nothing, other than to demonstrate the mechanics of the shutdown method I am showing.

Requirements

LabVIEW 2012 (or compatible)

Steps to Implement or Execute Code
1. Run the VI
2. When desired, press the Stop button
