Cirrus Link MQTT Engine Module

MQTT Engine Subscribe to Sparkplug data natively in Ignition Build secure, efficient Industrial IoT (IIoT) solutions with the MQTT Engine module. a powerful tool for connecting MQTT servers to Ignition and delivering data to both operational and business applications with dramatically reduced bandwidth usage. By leveraging a publish/subscribe architecture, MQTT Engine enables Ignition to consume Sparkplug-enabled data from edge gateways and MQTT-enabled devices like sensors, PLCs, RTUs, and OEM Edge Node Devices. These connections replace traditional host-based polling with a push-based, event-driven model streamlining communications, increasing data throughput, and enabling highly scalable IIoT architectures. Ideal for: wide-area SCADA systems or networks with constrained or expensive connectivity (like VSAT or cellular). Key features Increased data throughput and efficiency. Edge gateways handle the proprietary polling work and publish updates via MQTT, moving that load out to the network edge. This cuts overhead and supports more frequent updates from a wider range of devices, cameras, sensors, PLCs, and RTUs included. Self-learning tag creation. When MQTT Engine connects to a broker, it automatically discovers and builds Ignition tags from incoming Sparkplug payloads. No manual tag setup, and new tags become instantly available in Ignition's HMI, SCADA, and MES tools as they're learned. Built-in system health metrics. Generates health tags automatically for device status, gateway connectivity, and broker availability, viewable through prebuilt dashboards or custom views, making it easier to catch and diagnose issues early. Open source tools for device integration. Built on the Sparkplug MQTT topic and payload spec, so third-party device manufacturers can integrate using open standards. Cirrus Link backs this with documentation, sample code, and example applications. High availability and security. Outbound-only, TLS-encrypted connections from edge to broker keep all inbound ports closed, shrinking the attack surface. Edge devices can automatically fail over to secondary brokers and restore the primary connection once it's back, keeping uptime steady. File transfer over MQTT. Paired with MQTT Transmission, files like images and CSVs can move from edge to Ignition, triggered by scripts, control tags, or automation logic, with MQTT Engine receiving and storing them. Unified Namespace (UNS) enabled. As of version 4.0.23, Sparkplug messages can be organized into a UNS format, letting you choose between the standard Sparkplug view or a collapsed UNS-style hierarchy for enterprise-wide data visibility.
