CODESYS Engineering with AI support
The CODESYS Development System already includes many convenient features that make engineering easy and fast. To boost the implementation of your PLC application, use the tools bundled in the Professional Developer Edition. They provide you with even more powerful features and help you to work more effectively and securely.
CODESYS MCP Server: Product of the year 2026
Kempten, April 13, 2026
The readers of the trade magazine "Computer & Automation" have voted for their choice of Product of the Year 2026:
In the "Software and IT" category, first place went to the CODESYS MCP Server.
The add-on enables data exchange via Model Context Protocol (MCP) between AI systems with LLMs and the CODESYS Development System. This allows IEC 61131-3 blocks and PLC code to be generated, analyzed and optimized via prompt - including automatic error correction. The CODESYS MCP Server communicates with both cloud AIs and local LLMs.
We would like to thank everyone who gave us their vote!
Chatbot for CODESYS Online Help
Features:
- Plain text communication with the chatbot in case of problems with CODESYS
- Clear instructions based on the CODESYS Online Help
- Tested and approved by the CODESYS Support
Your benefit:
- Faster and easier access to information in the CODESYS Online Help with AI-based support, including specific application examples
- No AI hallucinations! It uses only the CODESYS Online Help and does not return any result if it cannot find suitable information there.
Status:
- Fully integrated into the CODESYS Online Help at https://www.helpme-codesys.com/
Code completion for ST code in CODESYS go!
Features:
- Context-based suggestions are displayed as you type.
- Easy acceptance at the touch of a button
Your benefit:
- Concrete and useful suggestions that you can accept simply by pressing a button, and edit as you wish
- The suggestions go far beyond the scope of the Intellisense® function already integrated in the CODESYS Development System -completion of function names based on library namespaces, for example). See screenshot above.
- Consideration of your specific program context in the current program block (up to 200 lines of code before and after the current position)
Status:
- Implementation only planned for CODESYS go!
- Currently running as a research project, planned for inclusion in the product
CODESYS MCP Server: Integrated data exchange with public AI systems via MCP plug-in for LLMs
Model Context Protocol (MCP) is an open standard protocol for data exchange between AI systems with large language models (LLMs) and external tools. The protocol was initially developed by the US company Anthropic (the manufacturer of the AI Claude) and is now also implemented by other AI manufacturers.
Features:
- Integrated MCP server as interface to LLMs in the CODESYS Development System:
Remote control of Engineering by the AI system - Automatic generation of POUs and PLC code
- Automatic detection and correction of coding errors
Your benefit:
- Have the structure of a new CODESYS project automatically built simply via a plain text command in the AI chat.
- Give your AI software commands to automatically generate program code and watch as the AI independently develops and corrects suggestions.
- Let the AI search for syntactic or structural errors in your application and develop suggestions for improvement.
- Have existing project code and its function explained to you.
- Use the AI as a virtual team member for simple programming tasks.
Status:
- Prototype of an integrated MCP Server for the CODESYS Development System
- Successful data exchange e.g. with Claude Desktop and OpenAI/GPT-5
- Available as a prototype for the CODESYS Development System (preview for V3.5 SP22)
- To be integrated into the product in the near future
Further AI possibilities within CODESYS
Research project for local LLMs with OpenVINO™:
“AI Coding Assistant in CODESYS powered by OpenVINO™“
Functions:
- Optimization of LLMs with OpenVINO™ for use on local devices and on-premises
- Automatic generation of POUs and PLC code, automatic detection and correction of coding errors, fine-tuning for PLC code generation
- OpenVINO GenAI deployment across multiple Intel architectures
Your advantage:
- No connection to the cloud – Edge deployment on Intel AI PCs for field service
- Control over your data – Programming support for source code and prompts that never leave your organization
- Performance – Use hybrid architectures that apply both discrete GPUs and integrated AI acceleration (iGPU/NPU)
Status:
- Research in collaboration with Intel
- Products planned in the medium term
External solutions
Features:
- SyntaxShift from KS Solutions AG: AI-based code conversion for various PLC standards (e.g., Siemens IL, SCL ↔ CODESYS ST)
- Additional options, e.g., for graphics to code / configuration / visualization
Your benefit:
- Significant time savings in code conversion
- Ideal for retrofit options and flexible manufacturer changeovers
Status:
- Available as a product/service from KS Solutions AG - coming soon to the CODESYS Store
Conclusion
- The CODESYS development team is working intensively to offer you integrated AI capabilities for your work with CODESYS.
- The first integration is already available, further products are planned.
