Industrial data accessible via enterprise OPC UA
A standards-based interface to SCADA device data for HMI, analytics, and third-party integrations.
What it is
The WizIIOT OPC UA Server exposes your SCADA device measurements and status information through OPC Unified Architecture, the industry standard for industrial device communication. Connected devices, meter readings, and system tags appear as a live, navigable hierarchy that integrates seamlessly with existing HMI and enterprise software. Real-time updates flow continuously from devices to any OPC UA client, and historical data is available for trending and compliance.
Key benefits
Standards-based integration
OPC UA is the universal language of industrial automation. Connect HMI software, data analytics platforms, and third-party tools without custom bridges or middleware.
Real-time visibility
Device values update live as meters and sensors report. Clients subscribe once and receive continuous data feeds, eliminating polling overhead and keeping decision-makers current.
Enterprise-grade security
Support for modern TLS encryption, certificate-based authentication, and role-based access control. Meets utility and industrial cybersecurity requirements out of the box.
Historical trending and compliance
Store and query historical device data for SLA reporting, regulatory audits, and root-cause analysis without leaving your platform.
Capabilities
- OPC UA address space mirroring real SCADA device hierarchy (controllers, meters, analog/digital tags)
- Real-time node value updates synchronized with internal messaging system
- Multi-policy security (None through OPC UA 1.05 encryption and certificate validation)
- Value and event history collection for historizable nodes with aggregate calculations
- JWT-based REST API for programmatic server configuration and client access
- Concurrent session management (500 max sessions, 50 subscriptions per session, 1-hour timeout)
- Large address space optimization for deployments with thousands of tags
- Compliance test nodes (analog, multistate, two-state data types) for interoperability validation
