OPC UA Interoperability & Integration Architectures

Need a reliable way to store OPC UA data in MS SQL or CSV databases for historical analysis, reporting, or analytics? In industrial environments, archiving OPC UA to MS SQL ensures your real-time data is captured, structured, and ready for dashboards, BI tools, or compliance reporting. In this guide, we explain how to log OPC UA data into SQL or CSV formats using OPC Easy Archiver and OPC UA Proxy, providing a flexible, scalable, and secure data archiving solution. Why Store OPC UA Data in a Database? OPC UA (Unified Architecture) is widely used in industrial automation for real-time data access, alarms/events, and historical data. However, real-time values are transient, making long-term insights impossible without persistent storage. Storing OPC UA data in a database allows you to: Perform historical trend analysis over time Generate automated reports for compliance or operations Integrate with enterprise analytics and BI tools Maintain traceability and cross-system interoperability Turn industrial signals into actionable business intelligence Solution: OPC Easy Archiver + OPC UA Proxy To reliably store OPC UA data, you can combine: OPC Easy Archiver: Logs real-time OPC data into databases or CSV files, with store-and-forward and automatic reconnection support OPC UA Proxy: Aggregates data from multiple OPC UA servers and exposes it to the archiver consistently and securely Together, they provide a complete OPC UA data storage pipeline from the source servers into structured databases for analytics and reporting. Key Benefits of this Approach Reliable Data Delivery: Handles network interruptions with store-and-forward and auto-reconnection. Flexible Storage Options: Supports SQL databases and CSV files, ideal for industrial IT setups. Scalability: Logs data from multiple servers and dozens of tags without performance loss. Cloud-Ready Integration: Compatible with cloud databases like Azure SQL for enterprise analytics. Simplified Architecture: No custom scripting required; everything is automated.
