Project Elements

Each project consists of different elements, configurations and settings. This section provides an overview of the different elements that can be found in a project.

In this section

• Configuration — Project-wide settings: access variables, configuration variables and application configuration.
• POU — Program Organization Units (programs, functions and function blocks) that hold your code.
• Global variables — Variables that are accessible from every POU in the project.
• Inputs & Outputs — The interface between the PLC program and the outside world, defined directly in code.
• Libraries — Reusable POUs and data types that can be shared across projects.
