In modern industrial systems, alarms and conditions are critical for ensuring operational safety and efficiency.
-
Alarms represent events that require immediate attention, such as equipment failures, threshold violations, or safety hazards.
-
Conditions track the state of these alarms over time, including when they were triggered, acknowledged, or cleared.
Together, alarms and conditions form a complete picture of your operational events. Collecting and archiving this data is crucial for real-time monitoring, compliance, and historical analysis.
However, managing alarms and conditions across multiple OPC UA Servers can be complex. Differences in server configurations, high data volumes, and secure storage requirements pose significant challenges. This is where OPC Easy Archiver and OPC UA Proxy come in.
Why Combine OPC Easy Archiver & OPC UA Proxy?
Individually, each product is powerful – together, they create a seamless, scalable solution:
-
OPC Easy Archiver handles data collection, storage, and management, ensuring your alarms and conditions are archived reliably.
-
OPC UA Proxy simplifies connectivity and security, aggregating data from multiple OPC UA Servers without complex networking or high server load.
By combining both, you get:
-
Real-time aggregation from multiple servers
-
Secure, encrypted data transfer
-
Flexible storage options, including relational databases and cloud solutions
-
Centralized access for monitoring and historical analysis
This combination ensures operational continuity, compliance, and efficient industrial data management.
