Ignition IIoT Certification Guide

Pass the IIoT test. Understand the system behind it. MQTT runs the modern SCADA system, and the Ignition IIoT certification proves you can build one. This guide takes you from the 1999 pipeline problem that created MQTT to a hardened, redundant architecture with MQTT Distributor, MQTT Transmission, and MQTT Engine, explaining the mechanism behind every setting so the answers stick.

Inside: publish and subscribe, topics, wildcards, and the last will; Sparkplug B births, deaths, sequence numbers, and rebirths; server sets, transmitters, and failover between brokers; outbound writes and the four gates that can block them; primary host ID, TLS end to end, and store and forward; redundancy, scale, and the Unified Namespace; and a one-page cheat sheet and a 50-question practice test.

Every chapter pairs the Inductive Automation and Cirrus Link video series with lab exercises you can run on a free trial gateway. Nothing here reproduces the certification test; every question is original. Charles Vance writes the LearnSCADA field guides for Ignition Core, Gold, and IIoT certification.
