Interoperability and OPC HDA
OPC HDA standardizes integration between clients and historical data servers, yielding faster time to value with less cost spent on custom engineering. Applications that are built to OPC HDA standards can enjoy plug-and-play interoperability with no customization or proprietary modifications required.
Applications of OPC HDA
Process Improvement
For customers seeking process-improvement tools, OPC HDA clients and servers can be used to collect, store, and analyze process data.
Distributed and Centralized Historical Data
OPC HDA applications can be used by enterprises for many solutions, from centralized data historians to local operations monitoring and troubleshooting.
Buffer and Store Critical Process Data
OPC HDA servers can act quickly to capture and commit data to file systems, enabling data to be held safely at rest until collection occurs.
Plug-in features
Ability to collect a value, quality, and timestamp from any data source in the Kepware server (e.g., drivers, plug-ins, or system tags).
Collection from both static and dynamic server tags.
Persistence to a volume on the local machine, which can be a fixed drive or removable media.
Provides (serves) access to historical data via OPC HDA v1.20.
Support for collection deadband.
Configurable data collection scan rates, as frequently as 10 milliseconds.
Configurable data retention policy.
Support for data timestamps with one millisecond resolution.
Ability to import historical data that has been backed up and removed from active use.
