Benefits for users

End users employ CODESYS for successful creation of simple and sophisticated automation applications for industrial controllers that are used in factories, mobile machines, power and building automation systems, as well as many other areas. Several features and properties of the system help in this work.

Everything is integrated in a single user interface

  • Complete IEC 61131-3 programming system – from classic PLC programming to object-oriented controller programming
  • Extensive features for convenient project engineering and commissioning of automation applications, such as data monitoring, scanning for application errors (debugging), and changing the application during operation (online change)
  • Optional add-on modules for methodical application development: UML, version management, static code analysis, profiling, and test automation
  • Configuration and commissioning of the most important industrial fieldbus systems or manufacturer-specific I/O systems
  • Seamless integration of optional add-on components for project engineering: Visualization, motion control / CNC / robotics, safety modules
  • Installation, maintenance, and training required only for a single user interface: Minimization of engineering effort
  • Extendable function range through additional products available in the online store and with on-board tools (programming of function or communication libraries in the IEC 61131-3 languages, for example)
  • Easy connection to a convenient Industry 4.0 platform for managing control landscapes per cloud
