Overview

The CODESYS Application Composer is used to create applications by using existing modules. The user composes, parameterizes, and connects the required modules to form a complete application. This configuration does not require knowledge of PLC programming and can therefore be done by technicians without programming experience. Internal generators create complete, well-structured IEC 61131-3 applications including the I/O mapping and visualizations.

The CODESYS Application Composer consists of two main components:

Module editor, which can be used to compose the software modules developed with the module declaration editor
Module declaration editor for developing modules
