e-plc-ladder

What problem does it solve?

This Skill automates translating natural-language PLC requirements into MELSEC IL ladder programs that run on the OpenPLC-based runtime, dramatically reducing manual drafting and verification time.

Core Features & Use Cases

• Automatically generates ladder logic from requirements for PLC simulation and runtime execution.
• Provides web AI mode with 7 ladder tools and a CLI Claude Code mode to support writer, simulator, and reviewer triad.
• Enforces MELSEC IL opcodes (LD, LDI, AND, ANI, OR, ORI, ORB, ANB, OUT, SET, RST, END) and TMR/CNT timers with 100 ms K1 granularity and grid-based layout rules.
• Supports common PLC patterns including self-hold, timers, and parallel logic with pseudo-simulation and static checks to guide safe designs.

Quick Start

Generate a self-hold ladder for a motor using natural language and run the pipeline to compile MELSEC IL and simulate.
