Micro-LLM as an assembler for industrial automation: low-level PLC/SCADA code generation from natural language on low-power devices

An innovative approach to the application of microscopic language models (micro-LLM) in industrial automation is proposed. Instead of traditional text generation, micro-LLMs are positioned as specialized assemblers for translating short operator commands in natural language directly into executable low-level code for controllers (PLCs) and dispatch systems (SCADA). The key aspects are an ultra-limited vocabulary, guaranteed deterministic output, and deep integration with the runtime environment of industrial systems. Focus on performance efficiency on resource-limited devices and enhance the intuitiveness of the human-machine interface (HMI) without compromising reliability. Architectural principles, security requirements, and potential impact on automated process control system operator interfaces are considered.
