1A.3.4 Historical Data Collection
High Historical Data Integrity
The ControlWave Historical Data Collection system offers exceptional historical data
integrity by providing time-stamped historical data storage in ControlWave flash memory.
The historical data is collected, through OpenBSI, on a scheduled or demand basis and
converted to .CSV and ODBC compliant file formats for use in spreadsheets and reports. If
data is missed due to a communication failure, it is collected when the communication is
reestablished and the PC historical database is back-filled with the missing data. This
distributed historical database architecture provides the greatest data reliability and
integrity during communication or PC failure.
Another important historical feature is the Audit storage and collection system. The Audit
Trail is a file stored in ControlWave flash memory containing significant events and time-
stamped alarms. The alarms stored in the Audit system provide a historical archive in
addition to the real-time alarm reporting system.
This file is also collected through OpenBSI and presented as a text file in the PC. This
functionality is extremely useful in providing an event trail during communication or PC
downtime or other system problem.
• Archive Collection – collection and storage to disk of the ControlWave archive data
• Audit Collection - collection and storage to disk of the ControlWave audit data.
• Exports data files to third party, CSV & ODBC applications
• DDE compliant for use with other popular Windows applications
