Guides
Practical guides on programming CODESYS PLCs with AI: what an AI agent can do in the IDE today, how to set it up, and how the available tools compare.
AI for CODESYS: what works today
What AI can do in CODESYS today: chat assistants, code completion and MCP agents that write, compile, download and verify PLC projects. Setup and limits.
Rung Coder vs. the official CODESYS MCP Server
The official CODESYS Development System MCP Server and Rung Coder compared: languages, CODESYS versions, HMI, online debugging, version control and licensing.
Generate Structured Text for CODESYS with AI
Let AI write IEC 61131-3 Structured Text in your CODESYS project: POUs, DUTs and GVLs, compiled in the real IDE and fixed until 0 errors and 0 warnings.
Generate CODESYS visualization pages with AI
Build CODESYS visualization pages from one prompt: buttons, lamps, sliders and text fields bound to PLC variables, laid out and checked for overlaps.
AI for Ladder Logic (LD) in CODESYS
Let AI write and edit Ladder Diagram (LD) in CODESYS: contacts, coils, seal-ins, timers, counters and compare boxes, verified against the IDE's own LD model.
AI for CODESYS SoftMotion and motion control
Use AI for CODESYS SoftMotion: axes, CiA402 EtherCAT drives, axis groups with 24 kinematics, CNC G-code and cam tables, verified with 1 ms sampling.
Try it on your own CODESYS project
Rung Coder is free for 2 months from your first sign-in, with no payment method needed. Windows 10/11 and CODESYS V3.5 SP18 or newer.
