New Solution Provides Unified, Standards-Based Alarm Management at the Edge

IOTech Systems, the leader in open edge computing, today announced the general availability of its Edge Alarm Service, a powerful new solution designed to revolutionize how industrial organizations monitor, manage and respond to alarms across complex edge environments.

As industrial edge systems grow in scale and diversity—spanning a wide variety of different devices, protocols, and operational technologies—alarm management has become a critical challenge and difficult to unify. IOTech’s Edge Alarm Service addresses this head-on with a standards-based, and technology-agnostic approach to alarm normalization, routing, and control.

“Our new Alarm Service empowers users with unmatched control over their edge alarms, delivering flexibility and interoperability across complex industrial systems,” said Keith Steele, COE at IOTech. “Built to scale, integrate, and adapt across any edge environment, it enables customers to respond to operational challenges with greater speed, clarity, and confidence.”

Built on Industry Standards for Maximum Compatibility

The Edge Alarm Service is built on the OPC UA Alarms & Conditions standard and aligned with IEC 62682. This ensures broad compatibility across industrial systems—from OT devices (e.g. BACnet, Modbus etc.) and PLCs to other sources of alarm data such as rules engines and analytics components. It can be deployed with IOTech Edge Central, integrated with open-source EdgeX Foundry or embedded within custom frameworks, enabling seamless alarm unification in virtually any industrial environment.

Leveraging an event-driven architecture, the service evaluates alarm data in real-time, generating standardized alarm events that can be viewed and managed by via a dedicated UI or a comprehensive REST API.

Open API Access and Smart Routing

IOTech’s Edge Alarm Service is designed for developers and integrators, with its powerful REST API providing full lifecycle access to alarm data and operations, including:

• Monitoring and managing alarms throughout their lifecycle
• Querying current and historical alarm states
• Managing alarms with functions such as acknowledgment, confirmation, shelving, and suppression
• Subscribing to alarm events for efficient data-driven applications
• Secure authentication and access control

The service also enables intelligent alarm routing to multiple endpoints including Email, SMS, MQTT, Webhooks and Telegram, ensuring critical alerts reach the right systems or personnel at the right time—enhancing responsiveness and operational safety.

Easy Configuration and Scalable Architecture

Alarms can be defined through simple configuration files or the REST API, supporting everything from basic thresholds to advanced multi-level models such as “high-high” critical events. With an architecture designed for scalability, the Alarm Service can process alarm data from many independent concurrent sources and is ready to grow with your edge deployment.

Intuitive Alarm Management UI

For end user customers or operational teams who choose not to layer their own management tooling on top of the REST API, IOTech provides a modern, intuitive web-based interface. Designed with usability in mind, the UI offers clear visualization, streamlined navigation, and real-time interaction, making alarm monitoring and management fast, efficient, and accessible to all levels of operators.
