Using LLMs to extract structured registers from industrial manuals

Plenty_Shine_8250 · reddit · 2026-08-19

Addressing the challenge of extracting structured register mappings from varied industrial manuals (Modbus, OPC UA, etc.), the user discusses architecture designs combining deterministic extraction and LLMs. Current experiments use LLMs as constrained schema planners to map headers without hallucinating values, though latency and generalization remain issues. The user seeks advice on balancing LLM utility with deterministic validation to ensure traceability and accuracy.
