The Working Area

Left Area

You find there three different elements:
Application
Task List
Device

Application

It is the menu where you can create and edit the Global Variable List that you can use in your application. In computer programming, a global variable is a variable with global scope, meaning that it is visible (hence accessible) throughout the program, unless shadowed. https://en.wikipedia.org/wiki/Global_variable

Task List

Here you will have two different elements listed. The ladder diagram and the Arduino code. By clicking on each one of the elements listed you will switch between them.

Device

By clicking the element on this section you will move to the area to create and edit the IO Mapping of your project.
