It is the backbone of many industrial control systems worldwide.<\/p>\n<h2>What Is MCP?<\/h2>\n<p>MCP (Model Context Protocol) is a standard that allows AI systems and large language models (LLMs) to interact with external tools and platforms. Think of it as a bridge between AI assistants and real-world systems.<\/p>\n<h2>How They Work Together<\/h2>\n<p>The CODESYS MCP add-on enables direct communication between AI systems and the CODESYS Development System. This means:<\/p>\n<ul>\n<li><strong>AI-controlled development<\/strong> \u2014 AI can navigate and operate the CODESYS environment<\/li>\n<li><strong>Automated routine tasks<\/strong> \u2014 POU creation, code editing, and compilation can be handled by AI<\/li>\n<li><strong>Context-aware code generation<\/strong> \u2014 PLC code is generated precisely within the project context<\/li>\n<li><strong>Project management automation<\/strong> \u2014 AI assists with managing automation projects<\/li>\n<\/ul>\n<h2>Recognition: Product of the Year 2026<\/h2>\n<p>The editors of Computer &#038; Automation have nominated CODESYS for the Product of the Year 2026 award for this MCP integration. The add-on enables seamless data exchange via MCP between AI systems with LLMs and the CODESYS Development System.<\/p>\n<h2>Open Source Option<\/h2>\n<p>For developers looking to experiment, there is an open-source toolkit available on GitHub: <strong>johannesPettersson80\/codesys-mcp-toolkit<\/strong>. This MCP server for CODESYS V3 enables interaction between MCP clients (like AI assistants) and CODESYS, allowing automation of project management, POU creation, code editing, and compilation via the CODESYS Scripting Engine.<\/p>\n<h2>What This Means for Industrial Automation<\/h2>\n<ul>\n<li><strong>Faster development<\/strong> \u2014 routine coding tasks handled by AI<\/li>\n<li><strong>Fewer errors<\/strong> \u2014 AI-generated code within proper project context reduces mistakes<\/li>\n<li><strong>Lower barrier to entry<\/strong> \u2014 AI assistance makes PLC programming more accessible<\/li>\n<li><strong>New possibilities<\/strong> \u2014 AI agents can monitor, optimize, and maintain PLC systems<\/li>\n<\/ul>\n<p>The integration of AI into industrial programming is no longer theoretical \u2014 it is happening now.
