Kepware local historian plug-in improves operating efficiency

    Kepware Technologies’ Local Historian Plug-In for KEPServerEX is a flexible, easy to use and cost-effective solution that provides trending, reporting, and analytics tools with access to historical data using OPC Historical Data Access (HDA).


    This Local Historian Plug-In leverages the KEPServerEX communications platform to transport information to its high-speed datastore. The Local Historian provides historical information to custom or off-the-shelf OPC HDA-compliant client applications for data visualization, reporting, and analytics. Because the Local Historian’s design decouples data storage and visualization, users can choose the visualization or reporting solution that best meets their unique needs.

    The Local Historian Plug-In supports high-speed logging to 10 milliseconds and tiered licensing for up to ten thousand tags. Open standards allow locally-stored data to be accessed from multiple clients with no additional cost per client connection

    Kepware has tested the plug-in with multiple third-party trending and reporting products to validate its OPC HDA implementation and ensure a seamless user experience.

    Historical information is critical to improve process throughput, manage assets and report to regulatory authorities. Both operations and engineering teams require solutions that can be located close to the data source, are capable of storing data at high speeds, and have the flexibility that teams need to efficiently respond to the requirements of the manufacturing line, drilling rig, test laboratory, pump station, or other industrial environment.

    A local historian can supplement the existing enterprise historian model used in most large-scale industrial environments like manufacturing, oil & gas and utilities. Although the enterprise historian will continue to have a place in large companies as the final perpetual archive of critical information, many organizations also have a need for a smaller, more flexible historian application that is easy to configure and provides open access to third-party analysis and reporting tools at the point of collection.
