CODESYS Safety – Integrated Safety Solutions for all Areas of Applications

CODESYS is your Software Partner for IEC 61508 PLCs

CODESYS Safety provides a complete safety solution for manufacturers developing safety controllers based on IEC 61508 SIL2 and SIL3 standards. The engineering platform is the basis of the CODESYS product families for visualization, motion, control, fieldbus configuration, and safety programming. 

CODESYS is a pioneer when it comes to integrating a whole range of different functionalities into one single tool. The integrated SIL2 and SIL3 Safety solutions are standard in the CODESYS IEC 61131-3 development system tool.


  • CODESYS offers the complete functionality required for safe automation solutions, such as:
    • Extensive know-how in compiler technology for 32-bit CPU architectures (CISC and RISC): Reliable execution of the safety software is guaranteed.
    • Extensive know-how in fieldbus technology with integrated solutions for almost all standard systems: The simplest and most reliable solution for combining safe and non-safe fieldbuses.
    • The CODESYS runtime system can be easily ported to different hardware and software platforms: Existing safety solutions can be ported to new environments.
    • CODESYS is used for a wide variety of applications and in a wide variety of industries, at machine builders, in mobile machines, on embedded systems, in the energy and process industry, in shipbuilding or in the aviation industry.
    • Comprehensive know-how in the field of safe automation: Over the years, our specialized safety team has successfully completed numerous customer projects and collaborated with TÜV Süd / TÜV Rheinland / BGIA. (German technical supervisory associations).
    • The Safety developers of the CODESYS Group know what is important when it comes to performing a risk analysis, meeting specified safety requirements or creating certification documents.
    • CODESYS offers reliable services to efficiently and successfully implement your functional safety projects.
    • CODESYS is familiar with the requirements of the certification institutes and helps you avoid errors and unnecessary iteration loops.
  • CODESYS Safety is a solution for safety controllers based on the IEC 61508 standard
    • CODESYS Safety offers a complete safety solution for manufacturers committed to developing safety controllers based on IEC 61508 SIL2 and SIL3 standards. Using CODESYS Safety can significantly reduce the manufacturer's development costs and improve certification efficiency. CODESYS has extensive expertise and years of experience in the Safety control field and can provide strong safety software support to safety control manufacturers.
    • The Safety Runtime System can be easily transplanted to different hardware platforms. The safe operation system developed according to the IEC 61508 standard adopts a componentized design and can easily run on different hardware platforms such as Tri Core, ARM or PowerPC.
    • CODESYS has an independent team dedicated to the development of CODESYS Safety modules. During software development, the developers conducted a rigorous risk analysis for the safety control application area to ensure that CODESYS Safety meets the specified safety requirements.
  • Hardware and operating system independence
    CODESYS is a manufacturer-independent and operating system-independent comprehensive and flexible system.
    The hardware independent integration offers sustainability for already deployed applications, and the possibility to start developments before having the hardware.
  • Highest possible flexibility
    Programmers benefit from the simultaneously use of six common programming languages (ST, SFC, LD, FBD, CFC, IL) and the possibility to integrate C or Python.
  • Performance improvement
    CODESYS customers enjoy regular updates and upgrades free of charge. Upgrades enhance the overall functionality, security and performance of the CODESYS software and extends its lifecycle as well.
    The latest version of CODESYS can be downloaded free of charge from our CODESYS North America Store.
  • Online Changes
    CODESYS includes the possibility of changing the program without effecting the process - securely from all over the world.
  • Availability of a wide range of tools
    For efficient developments and diagnostics CODESYS has integrated analysis test, simulations, and offline tests. CODESYS includes efficient configuration, commissioning, and debugging tools to assist engineers throughout the development of their projects.
