CODESYS: Leading Industrial Automation Software

Picture
CODESYS (Controller Development System) is the industry-leading, open-source automation software suite designed for the IEC-61131-3 international standard. Operating independently of device manufacturers, CODESYS can be used with hundreds of different controllers, making it highly adaptable and versatile.
With CODESYS, you can:
  • Utilize Multiple Programming Languages: Take advantage of the five IEC 61131-3 programming languages (ladder diagram, function block diagram, sequential function chart, structured text, and instruction list) for application programming, providing flexibility in development.
  • ​Run Intelligent Devices with CODESYS Runtime System: Transform industrial PCs from different manufacturers (including Phoenix Contact, WAGO, Siemens, and others) into CODESYS-compatible controllers using available CODESYS SoftPLC systems.
  • Leverage Comprehensive Fieldbus Support: Directly integrate different fieldbuses in the CODESYS programming system, such as PROFIBUS, CANopen, EtherCAT, PROFINET, and EtherNet/IP, with additional support for BACnet and KNX.
  • Integrate Communication Protocols Seamlessly: CODESYS supports both proprietary and standard protocols, including OPC, OPC UA, https, and MQTT. Select protocols are available in the form of encapsulated libraries for accessing public clouds like AWS (Amazon Web Services) and Microsoft Azure.
  • Create and Animate Complex Visualizations: Design sophisticated visualization masks directly within the programming system. An optional toolkit allows the creation of custom elements. These visualizations can be used for testing, commissioning, and plant/machine operation on integrated displays, in a Windows/Linux portable runtime, or on an HTML5 web browser.
  • Ensure Secure Industry 4.0 Communication: Utilize the Edge Gateway software to facilitate communication between Industry 4.0 compatible devices. The software features top-tier security, rated A+ by SSL Labs
CODESYS is available in multiple editions, including Professional Developer and Application Composer (which doesn't require prior PLC programming knowledge). With over 400 device manufacturers offering CODESYS-compatible automation devices, users around the world trust CODESYS for a wide range of automation applications.
