Making LLMs Reliable for Industrial Q&A: Evidence-First Design

General chatbots hallucinate; industrial answers must be verifiable. This article describes the evidence-first design pattern: curated corpora, hybrid retrieval, constrained synthesis, and inspectable output.

Word Embeddings and Semantic Search: How Modern Retrieval Works

Semantic search matches meaning, not spelling. This article explains embeddings, vector similarity, and why hybrid keyword-plus-vector retrieval is the robust production pattern.

What Is a Data Historian? Time-Series Data in Process Plants

Process data is time-series data, and general-purpose databases handle it poorly. Historians are purpose-built for collecting, compressing, and serving millions of process values.

The 4–20 mA Signal: Why Analog Measurement Endures

Decades after digital fieldbuses arrived, the 4–20 mA loop still dominates instrumentation. The reasons are practical, not nostalgic: wire break detection, distance, and noise immunity.

PROFINET, EtherNet/IP, and EtherCAT: Comparing Industrial Ethernet

Three standards dominate industrial Ethernet. They share the same cables and switches — but their timing, topology, and engineering models differ in ways that matter.
