Industrial IoT Software Guides

Practical guides for IIoT software buyers and implementers — from architecture decisions and platform evaluation through brownfield connectivity and pilot design. Written for practitioners, not procurement committees.

• Architecture

  Building Your First Unified Namespace

  How to structure MQTT topic hierarchies using the ISA-95 model. Covers topic hierarchy design, Sparkplug B alignment with UNS, the telemetry vs. attributes split, and the failure modes that break UNS deployments at scale.
  ›
• Evaluation

  Industrial IoT Software: An Independent Buyer's Guide

  The OT-integration vs. fleet-management decision fork that most evaluations skip, and why picking the wrong one wastes a six-month pilot. Covers evaluation criteria for each path, vertical-specific considerations, and a platform comparison table.
  ›
• Connectivity

  Extracting Telemetry from Legacy PLCs Without Native Ethernet

  Hardware and software guide for connecting older Allen-Bradley, Siemens, and Modbus RTU equipment to a modern IIoT data pipeline without replacing the PLC. Covers DH+, DH-485, DF1, S5 AS511, and the three-layer extraction architecture.
  ›
• Evaluation

  How to Structure an IIoT Pilot That Can Scale

  A framework for designing proof-of-concept deployments that survive contact with the rest of the factory. Covers the four-persona scoping requirement, Purdue Model network architecture, semantic normalization testing, and the edge management blindspot.
  ›
• Architecture

  The Read-Only Data Pipeline

  How to use hardware-enforced unidirectional data flow to protect safety-critical OT systems while feeding enterprise analytics. Covers the split-proxy architecture that makes data diodes work, FEC, NTP isolation, and why native TCP protocols cannot cross the hardware gap.
  ›
• Evaluation

  Protocol Compatibility: What Your Vendor Won't Tell You

  The gap between claimed protocol support and actual connectivity in your environment. Covers firmware version gaps, Siemens Optimized Block Access, Allen-Bradley CIP connection limits, Modbus endianness, and how to run a pre-purchase compatibility test that surfaces real problems.
