The Ovation® Process Historian provides mass storage and retrieval of process data, alarms, sequence-of- events (SOE), and operator actions for Windows-based Ovation® systems. The speed, power, and flexibility of the historian allow it to organize vast amounts of real-time process data and present meaningful information to all users of process information, including operators, engineers, and maintenance personnel. Integrated tools provide viewing, sorting and data analysis at the Ovation control system without the need for additional software, and separate applications bring similar capability to
users' desktop computers.
To meet the various system application needs, the historian collection function (known as a "scanner") can be deployed either on the historian server or remotely on one or more operator stations located throughout the Ovation system.
By distributing the collection of process values and messages, this data will be processed locally and forwarded to the historian server for long-term storage. Therefore, an outage by the server will not interrupt data collection, as this data is buffered until communication with the server resumes. A second redundant scanner can execute on another station to provide additional protection of data loss due to a failure of the primary scanner host computer.
