Project elements

POUs

A POU (Program Organization Unit) contains a well-defined part of the program for modularization and structuring. The POU has a defined interface with inputs and outputs and can be called and executed multiple times.

Configurations

Zugriffsvariablen / Access Variables

Access variables are variables that are also available outside the program. They are used to display and describe values in the HMI or to establish connections to the program via MQTT .

Config variables

Use configuration variables to assign complete addresses to variables declared in function blocks with incomplete addresses that are to be mapped to device I/O.

Applications

Global variables

Global variables apply to the entire project and can be used by all POUs.

Tasks

Tasks control the execution of programs, functions and function blocks. They can be executed cyclically or trigger-controlled.

Programs

Program parameters

Data types

Data Types are custom definitions of data types that can be used throughout the project.
