AI-Powered PLC Programming Assistant
Intelligent assistance for Siemens SCL & Ladder Logic development
LadNix is an AI-powered development assistant built specifically for PLC engineers working with Siemens automation systems. It provides intelligent support for Structured Control Language (SCL) and Ladder Logic (LAD), helping engineers write, understand and improve PLC code faster and more safely.
Unlike general-purpose AI tools, LadNix is designed for industrial environments where correctness, determinism and safety matter. The assistant understands IEC 61131-3 concepts, Siemens-specific language rules, and common automation patterns used in real-world production systems. See Siemens TIA Portal for more.
LadNix can explain existing PLC blocks line-by-line, generate new SCL or Ladder Logic code from natural language, suggest safe refactorings, and highlight potential logic or safety issues. All suggestions are presented as drafts with full user control before applying changes.
Built on: Eclipse Theia and Python
Describe what you need in plain language and get production-ready SCL or Ladder Logic code in seconds.
Understand legacy PLC code quickly with AI-powered line-by-line explanations.
Get suggestions for cleaner, more maintainable code while preserving functionality.
Identify potential logic issues, race conditions, and safety concerns before deployment.
Industrial automation engineers face unique challenges that generic AI coding assistants cannot address. PLC programming requires deep understanding of real-time control systems, safety-critical operations, and industry-specific standards like IEC 61131-3. LadNix was built from the ground up to understand these requirements and provide relevant, safe, and accurate assistance.
Whether you're working on conveyor systems, robotic cells, process control, or packaging machines, LadNix understands the patterns and best practices used in industrial automation. The AI has been trained on real-world PLC code examples and understands concepts like function blocks, data blocks, organizational blocks, timers, counters, and safety interlocks.
LadNix provides intelligent assistance for the entire Siemens S7 family, including S7-300, S7-400, S7-1200, and S7-1500 controllers. The assistant understands the differences between these platforms and can help you write code that is compatible with your target system. Whether you're using TIA Portal V15, V16, V17, V18, or V19, LadNix integrates seamlessly with your development environment.
Engineers use LadNix for a variety of tasks in their daily work. Generate new function blocks from natural language descriptions, such as "create a motor control block with soft start and overload protection." Understand legacy code by asking LadNix to explain complex logic step by step. Refactor existing code to improve readability and maintainability while preserving functionality.
LadNix also helps with documentation by generating comments and descriptions for your code blocks. The assistant can identify potential issues like race conditions, missing error handling, or non-standard coding patterns that could cause problems in production.
We understand that industrial code is sensitive intellectual property. LadNix is designed with privacy in mind. The backend runs locally on your machine, and only the specific prompts you send are transmitted to the AI service. Your complete codebase never leaves your computer, and we do not store or train on your code.
