Faster PLC Engineering in CODESYS with the “Artificial Colleague” Interview

Overview

Complete PLC projects faster than ever before — AI supports you like an “artificial colleague” via Model Context Protocol (MCP), the standard interface for data exchange with Large Language Models (LLMs). The AI edits the PLC project directly via the integrated MCP server in the CODESYS Development System. The MCP server allows you to use LLMs from any supplier, such as Claude, OpenAI, Gemini, or local models ( e.g. based on Intel’s OpenVinoTM). Example: “Create a function block for two-point control with hysteresis in the CODESYS project and instantiate it in the main program.” With this prompt, the AI generates the block including variable declarations and instance call. It compiles the project, automatically corrects compiler errors and recompiles the project. While these development iterations run automatically, you retain control and can intervene at any time. Your benefit: Many small time-saving features significantly speed up your work. Additionally, the AI helps you structure automation projects, such as those derived from base projects. For example, convert complete machine sequences into PLC code based on a hand-drawn sketch and some descriptive text. Give it a try: Use the CODESYS Development System together with the MCP-Server and your favorite AI.
