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.

📄️ POU

POUs (Program Organization Units) are the basic building blocks of a PLC program. They can be functions, function blocks, or programs. POUs are created in logiccloud via the project tree. Within the node POUs you can create a new POU. To do this, right-click or go to the icon with the three dots and select Add POU, assign a name, select the type of POU you want to create, and the language you want to use. The structure is created automatically.

📄️ Configuration

The configuration of a project contains all the necessary settings and definitions for the project. This includes access variables, configuration variables, and application configuration. You need to have at least one configuration in your project, but if you need to, you can define multiple.

📄️ Inputs & Outputs

Inputs and outputs are the interface between the PLC program and the outside world. Inputs are used to read data from sensors or other devices, while outputs are used to control actuators or other devices. In logiccloud, inputs and outputs are defined directly in the code.

📄️ Global variables

Global variables are variables that are accessible from all parts of the program. They are defined in the project tree under Global Variables.

📄️ Libraries

Libraries are used to store and reuse POUs and data types. Libraries can be used in multiple projects, and they can be imported into a project.
