CODESYS Development System
The CODESYS Development System is the market-leading IEC 61131-3 programming system used to implement hundreds of thousands of applications in various areas of industrial automation worldwide. The software tool contains all editors of the standard and generates executable binary code for the most important CPU platforms used in industry from the code objects created using integrated native code generators. This is processed by the corresponding CODESYS Control runtime system. Many powerful functions support the task of creating, commissioning, and debugging control applications efficiently and conveniently - without the need for additional tools. A small selection:
- Assistance for input and configuration
- Sophisticated and field-proven library concept for easy reuse of application code
- Project comparison across all editors
- Extensive debugging and online features for troubleshooting, for optimizing application code, and for speeding up testing and commissioning
CODESYS supports genuine object-oriented programming (OOP) according to IEC 61131-3 3rd Edition in all languages of the standard. Its use is optional - if required, the use of OOP can be encapsulated in libraries that can be called according to the functionality required. Of course, CODESYS offers comprehensive security features to secure the source and binary code, communication, and operation of the controller via established standards such as X.509 certificates.
In addition to programming, the CODESYS Development System also covers other tasks that are required for the use of industrial controllers. For example, configuration tools for convenient connection to fieldbus systems such as CAN/CANopen, PROFIBUS/PROFINET or EtherCAT are fully integrated into the tool, and associated protocol stacks are available in the form of libraries. Within the tool, users can also generate graphical user interfaces for program testing, diagnostics, and operating the device, optionally with an integrated connection to Apache Subversion or Git for version management, as well as additional tools for static code analysis or runtime measurement of the application code.

CODESYS Virtual Control SL / CODESYS Virtual Safe Control SL
Virtual and secure industrial controls
Although software is becoming increasingly important in control systems, its execution is still tied to physical hardware. Virtualization using container technology now makes it possible to abstract the hardware. This means that PLCs can be executed on different platforms such as industrial PCs, edge computing systems, or servers.
The necessary components of the PLC are “deployed” as an image in a container. This means that several PLC instances can be operated in parallel, allowing flexible and scalable utilization of memory and computing capacities. Physical or virtual network interfaces can be mapped to the PLC so that several fieldbus systems can be operated via a single port. The real-time capability of the controller is ensured by the operating system or real-time patch.
In safety-critical applications, e.g. in accordance with IEC 61508, compliance with safety requirements is crucial. A dual-channel control architecture is required for SIL3 at the latest. Virtual controllers enable software-based dual-channel capability without special hardware thanks to “Diversified Encoding”. The technology is based on “coded processing” and offers the possibility of detecting errors in the data and control flow of the PLC programs through redundant software channels. These channels execute the safety application one after the other on the same CPU core. In combination with other test mechanisms, this process achieves a level of safety comparable to that of dual-channel hardware - but without the need for special hardware.
As a control platform, CODESYS is device-independent per se. With CODESYS Virtual Control and CODESYS Virtual Safe Control, virtualization can be used directly in industrial automation. Your advantages:
- High cost and effort reduction for procurement, installation, and maintenance
- No need for special safety hardware
- Greater efficiency by freeing up control cabinet space and eliminating power supply units and cabling
- Optimized operating technology (OT) through central management of PLCs with modern IT methods
- Increased IT security through “Secure by Design”: Isolation of individual components in containers
- Simple generation of additional virtual controllers on existing resources instead of installing additional hardware

CODESYS Visualization
The CODESYS Visualization contains display variants (runtime clients) for the display of graphical visualization images that were created within the market-leading IEC 61131-3 programming system CODESYS Development System. These variants run as separate products on different platforms: CODESYS HMI is a variant for IPCs, the CODESYS WebVisu uses HTML5 to display the generated graphical visualization images within web browsers. With CODESYS TargetVisu, the generated images can be loaded directly onto suitable control systems with built-in or connectable displays to be used there. Using various communication options, control data can also be visualized on remote devices. Many available graphical operating elements and functions, such as language switching, integration of HTML pages, responsive design or integration of web applications, allow for simple development of intuitive user interfaces. In addition, all kinds of HTML5 canvas elements can be used for visualization and animation.
