Industrial control systems (ICS), SCADA platforms, DCS environments, and OT networks operate critical physical processes. A cyber incident can trigger safety events, equipment damage, environmental releases, or extended service disruptions. Zero Trust Architecture (ZTA) addresses these high-consequence environments. It assumes no user, device, application, or network segment deserves implicit trust. Physical location or network placement…
Modbus is one of the rare industrial technologies that has outlived several generations of automation hardware, networking, and software. It is not glamorous, and it was never designed to be a complete industrial data platform, yet its straightforward messages still connect programmable logic controllers (PLCs), remote terminal units (RTUs), variable-frequency drives, power meters, sensors, analyzers,…
Industrial data historians are no longer confined to proprietary control-room stacks. In 2026, an operations team can assemble a serious time-series platform from open technologies, connect it to PLCs and gateways, and still preserve the auditability, retention policies, and analytical depth expected in a modern plant. That opportunity is exciting, but the word “historian” needs…
Factories rarely suffer from a lack of data. They suffer when valuable data is trapped inside PLCs, historians, SCADA servers, gateways, and machine controllers that speak different languages. MQTT Sparkplug B offers a disciplined way to move that data through an industrial MQTT infrastructure while preserving device identity, state, metrics, and operational meaning. The result…
