CODESYS GmbH
About us
The CODESYS GmbH is part of the CODESYS Group and ranks among the world’s leading software companies in automation industry. The company’s main focus is the distribution of CODESYS, the integrated, well-known IEC 61131-3 development environment (IDE) for controller/PLC applications and CODESYS Control, the platform-independent runtime system/SoftPLC. A new feature is the hardware-independent use of the runtime system via container or hypervisor as a virtual PLC on any platform – since the beginning of 2025 even for virtual safety controllers in accordance with IEC 61508 SIL3. CODESYS offers integrated product extensions for the use and configuration of fieldbuses like CAN/CANopen, Profibus, and industrial Ethernet such as EtherCAT or PROFINET, for the generation and display of professional user interfaces (visualizations) and for complex motion control tasks, e.g. for CAMs and CNC/robotics applications. DIN 61508 Safety applications for SIL2 and SIL3 can also be developed with integrated and certified Safety solutions to suit the given requirements. The CODESYS Automation Server is an Industry 4.0 platform for the convenient administration of control networks and for data recording and analysis.
More than 400 manufacturers of programmable automation components such as PLCs, IPCs, fieldbus couplers or drives use CODESYS as their programming interface. Thus, the software suite is used for a wide variety of industrial applications, for example for the automation of production machines and mobile machines or for the automation of power generation systems and buildings. This enables the users of devices to develop specifically adapted PLC application software for their special purpose.
CODESYS natively includes all essential technologies and features for applications in Industry 4.0 and IIoT environments. Therefore, CODESYS is the platform for implementing automated processes and cycles while utilizing IT and internet technologies. The cloud-based administration platform CODESYS Automation Server supports the most important service tasks of compatible devices and allows for a centralized and easy administration via web interface.
Numerous interfaces and toolkits help users adapt the powerful functionality of CODESYS to their specific needs. If required, the CODESYS Group offers professional adaptation support. Practice-oriented trainings and qualified consulting for efficient application development help users solve their automation tasks.
Products & services
CODESYS
The manufacturer-independent IEC 61131-3 automation software for the complete software side of automation.
CODESYS Development System
It seamlessly integrates IEC 61131-3 editors, debuggers, and compilers, enabling convenient engineering of all automation tasks. Optional add-on products from the CODESYS Store extend the range of functions, including integrated tools for optimized application creation and connection to simulation tools. A new feature is AI-based engineering support via an MCP server that is fully integrated into the CODESYS Development System. The solution has been nominated for the “Products of the Year 2026” reader's choice award by the trade journal Computer&Automation and for the ElectroTEC Pioneer Award by Vogel Verlag.
CODESYS Runtime
In the CODESYS Store, users can find SoftPLCs for common hardware platforms such as Raspberry Pi or IPCs on which created automation applications can be executed. New: Virtual controllers via containers – since the beginning of 2025, even virtual safety controllers according to IEC 61508 SIL3, certified by TÜV Süd. This means that safety applications can now be implemented without expensive safety controllers.
CODESYS Automation Server
Industry 4.0 platform for easy management and control of controllers via a web interface. Additional benefits: Remote access to applications/web visualizations in compliance with IT security, as well as data storage and analysis. New: Convenient management of security certificates on a central platform. If required, the CODESYS Automation Server can now also be hosted on local servers (“on-premises”).
CODESYS Visualization
Users create and animate professional user interfaces directly in the CODESYS Development System. These can be displayed in the Development System, on industrial PCs, directly on the PLC, or in a web browser.
CODESYS Fieldbus
Integrated fieldbus support, e.g., for PROFIBUS, CAN, and many Industrial Ethernet protocols such as EtherCAT, PROFINET, or EtherNet/IP, accelerates the implementation of automation projects.
CODESYS Motion CNC Robotics
Integrated extension of the IEC 61131-3 tool with editors/configurators for cam disc and 3D CNC applications with DIN 66025 description and robot axis groups. Useful library blocks included.
CODESYS Communication
Proprietary and standard protocols that are seamlessly integrated into the platform make communication easy, e.g., for MQTT OPC UA, KNX, or BACnet.
CODESYS Safety
The virtual controller, certified by TÜV Süd according to IEC 61508 SIL3, enables the implementation of safety applications independently of specific hardware. Certified connection of safety I/Os via F-Host (Profisafe) and FSoE (EtherCAT Safety). Integrated engineering of available safety components in an IEC 61131-3 project along with the functional application.
CODESYS User Services
Support for customers in implementing their applications with CODESYS. If required, with professional customization support, practical training, and expert advice on efficient application development.
CODESYS Virtual Safe Control SL - the virtual safety PLC
Whether boards, IPCs, or IT farms: With CODESYS Virtual Safe Control SL, every system is turned into one or more safety controllers – completely independent of the hardware infrastructure! The virtual safety PLC is certified according to IEC 61508 SIL3, currently for x86-based systems with Profinet/Profisafe (F-Host) and EtherCAT Safety (FSoE). Support for ARM-based platforms will be added in the course of 2026. Benefits for users: Massive savings in costs and effort for procurement, wiring, and maintenance, while at the same time strengthening IT security.
