What is the difference between a single-process shared variable and a local variable?
A single process shared variable is more like a global variable, because it can be accessed from any VI in your hierarchy. Local variables are strictly local to the single VI where they reside.
Shared variables are a relatively new feature, while local and global variables are ancient. As such, shared variables are in many ways more modern and integrate better into state-of-the-art coding guidelines.
Shared variables contain error terminals so you can enforce execution order. local variables have no such thing.
A shared variable can stand on its own, while a local variable is always tied to a front panel object.
You need a project for shared varaibles.
You can easily turn a single process shared variable into a network shared variable later in the development, without the need to rewrite any code.
