Industry-standard OPC access to live SCADA data
Connect legacy and modern OPC clients to real-time SCADA tag values and alarm notifications without custom integrations.
What it is
WizIIOT OPC DA and AE Server is a Windows service that exposes your SCADA system's live tag data and alarm events through the industry-standard OPC Data Access (DA) and Alarms & Events (AE) protocols. Any OPC-compatible client—SCADA packages, analytics tools, energy management software—can immediately connect and pull real-time values, historical trends, and critical alarms without requiring custom adapters or point mapping.
Key benefits
Plug-and-play integration with OPC clients
Support any OPC DA/AE client out of the box. No custom drivers, no middleware, no integration coding—just register the server and connect.
Live updates at scale
Handle high-throughput real-time data with millisecond-latency callbacks. Efficient in-memory caching keeps thousands of tags responsive.
Unified alarm visibility
Route all SCADA alarms and events—meter faults, device disconnects, system events—through standard OPC AE, so operations teams see everything in their existing HMI.
Windows-native security and deployment
Runs as a Windows service with COM-based registration, DCOM authentication, and optional HTTPS encryption. Deploys via installer with no extra dependencies.
Capabilities
- Expose real-time SCADA tag values to any OPC DA client via Windows COM interface
- Route meter, device, communication, and system alarms to OPC AE subscribers
- Support concurrent OPC client connections with thread-efficient virtual-thread processing
- Cache thousands of tags in memory for sub-second response times
- Configure server behavior (update rate, cache size, security) at runtime without restart
- Deliver automatic updates when underlying SCADA data changes (push-based real-time feed)
- Integrate with legacy HMI systems and modern SCADA analytics platforms simultaneously
