Ignition

Ignition by Inductive Automation is a modular, database-centric industrial SCADA and IIoT platform built on open standards (OPC UA, MQTT, SQL, Python/Jython) that unifies HMI, MES, and enterprise connectivity into a single, web-launched architecture. Its standout feature is the unlimited licensing model — customers pay per server with no caps on tags, clients, screens, or connections — which dramatically reduces cost of ownership as plants scale from a single line to enterprise-wide deployments. Ignition’s Perspective module delivers responsive, browser-based visualization accessible from any device, while its Tag Historian, Alarm Journal, and Transaction Groups provide out-of-the-box MES-grade data management that rivals dedicated historians. For controls engineers and IT/OT managers, Ignition streamlines workflows like real-time production dashboards, SQL-backed reporting, REST API integrations with ERP/MES systems, and MQTT-based IIoT edge-to-cloud architectures, making it the platform of choice for organizations that want open, scalable infrastructure without per-tag or per-client licensing traps.
