OPC Redundancy from OPC Expert is designed for engineers who can’t afford data interruptions. It ensures continuous data flow between OPC clients and servers by automatically switching to a backup server when the primary goes down. It fits seamlessly into legacy and modern environments with support for OPC DA and OPC UA.
Whether you’re running HMIs, historians, or custom automation systems, OPC Redundancy provides configurable failover strategies, runs as a background Windows service, and eliminates the need for manual intervention. The result? Reliable data delivery, simplified setup, and fewer late-night support calls.
Specifications
Automatic Failover
Seamlessly switches to a backup OPC server when a connection drops—no manual action is required, and there is no data interruption.
Supports OPC DA and OPC UA
It works with legacy and modern OPC servers, ensuring you don’t have to rip and replace existing infrastructure.
Hot, Warm, and Cold Redundancy Modes
It gives you full control over how backup servers engage—whether instantly, with a delay, or manually—so you can match redundancy behavior to your operational requirements.
Custom Trigger Configuration
Failovers don’t just happen on connection loss—you can define triggers based on stale data, thresholds, or your logic to ensure intelligent switching.
No Data Loss During Failover
Keeps streaming data from all servers so that, even during a switch, your clients don’t experience gaps or missing data.
Runs as a Windows Service
It keeps working in the background—there is no need for a user to be logged in. It is ideal for unmanned systems and high-availability environments.
Drag-and-Drop Visual Setup
Configure redundancy by dragging in your server icons and setting logic visually. It’s quick, intuitive, and reduces the risk of errors.
Embedded OPC Server
It makes integration with HMIs, historians, and other third-party clients seamless, passing data through a consistent interface regardless of the source server.
Advanced Diagnostics and Troubleshooting
It gives you real-time connection data and logs to spot issues before they become failures.
Scalable Architecture
Whether managing a single production line or a multi-site enterprise, OPC Redundancy grows with you—no need to reconfigure as you scale.
