概述

PLC Skill 是一个可扩展的知识库，适用于 OpenClaw、Cursor、Claude Code 和 其他需要推理PLC逻辑、控制的LLM驱动开发工具 序列、互锁、报警以及厂商专用自动化环境。

该技能被组织为两层系统：

1. 通用PLC层：扫描周期跨厂商工程指导 推理、状态机、输出所有权、互锁、调试、代码 审查，以及IEC 61131-3风格逻辑。
2. 供应商层：针对术语、语法、内存的平台特定路由 模型、项目结构、软件行为以及官方文档。

这种分离帮助AI助手避免混淆供应商生态系统，避免弥补 不支持的语法，或者将每个PLC请求都扁平化成模糊的IEC风格代码。

能力

• **结构化文本（ST）、梯形图（LD）的逻辑设计与生成，

PLC Skill

Production-grade AI agent skill for industrial PLC programming. It combines a vendor-neutral engineering layer with vendor-aware routing so agents can produce structured, reviewable IEC 61131-3 control logic instead of generic PLC pseudocode.

Overview

PLC Skill is an extensible knowledge base for OpenClaw, Cursor, Claude Code, and other LLM-powered development tools that need to reason about PLC logic, control sequences, interlocks, alarms, and vendor-specific automation environments.

The skill is organized as a two-layer system:

1. Common PLC layer: Cross-vendor engineering guidance for scan-cycle reasoning, state machines, output ownership, interlocks, debugging, code review, and IEC 61131-3 style logic.
2. Vendor layer: Platform-specific routing for terminology, syntax, memory models, project structure, software behavior, and official documentation.

This separation helps an AI assistant avoid mixing vendor ecosystems, making up unsupported syntax, or flattening every PLC request into vague IEC-style code.

Capabilities

• Logic design and generation for Structured Text (ST), Ladder Diagram (LD), Function Block Diagram (FBD), and Sequential Function Chart (SFC) oriented work.
• State machines and sequencers with explicit state ownership, transition conditions, and output mapping.
• Code review and refactoring for scan-cycle risks, multiple writers, hidden latches, unclear interlocks, and maintainability problems.
• Debugging and troubleshooting using observable-first workflows for timers, edge triggers, resets, alarms, and sequence faults.
• Vendor-aware routing for cues such as TIA Portal, Studio 5000, GX Works, Sysmac Studio, TwinCAT, CODESYS, and related platform terminology.

See SHOWCASE.md for examples of how the skill changes typical AI-generated PLC output.

Support Depth

Do not assume every vendor path has the same depth. When a platform is unknown or only partially covered, the skill should answer from the common PLC layer and mark vendor-dependent details clearly.
