OA2history is the OAenterprise component that provides process data storage, retrieval, and presentation services to give operators, engineers, and managers a way of viewing current, recent, and past operational details as a function of time.
With OA2history, you can:
Configure any or all attributes in the OAenterprise system for historical storage.
Save time-series data for all OAenterprise-supported data types, including strings, integers, floating points, and Boolean values.
Create customized trending displays of pre-configured or ad hoc streams of time-series data.
Analyze trends in processes in order to plan process changes.
Set up value dead-banding and/or time slicing preprocessing parameters for each attribute for high-fidelity, yet efficient data storage.
Provide for fault-tolerant, redundant storage and retrieval configurations to ensure high availability of process and related historical data. - Route storage to up to three local and/or remote storage destinations. - Transparently retrieve data from OA2history as a whole or from any subset of its storage locations - from anywhere within OAenterprise. - Manage distributed history vaults and repositories for secure, reliable storage and instant access.
Use OAenterprise general capabilities, in conjunction with those of OA2history, to provide for unmanned operation and management of the history system.
Use OLE Automation interfaces to provide interoperability between automation clients and OA2history for retrieval and management operations.
Utilize multiple History Vaults- With OA2history’s scatter/gather model, you can store (scatter) data in and transparently retrieve (gather) data from multiple history vaults, each running on a different node to provide built-in redundancy. A few simple configuration settings eliminate the possibility of a single point of failure.
