Scripting is writing code to complete a specific task. In Ignition, scripting means using Python in the event based system. Almost everything in Ignition supports scripting by right-clicking the object in the designer and selecting the "Scripting..." option. Scripting and Expression bindings are sometimes confused, but have completely different functions. Scripting is used to create complex logic, while an Expression binding is a single command that evaluates to a single value.
