The IP compliant ControlWave opens the door for owner controlled access via Web Pages. Any ge- neric web page builder can be employed to create user defined pages to access ControlWave. The web pages are populated with these pre-configured ActiveX controls.

Required Software

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 histori- cal archive in addition to the real-time alarm report- ing 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

•Microsoft Internet Explorer

•Bristol ActiveX controls

Historical Data Collection

High Historical Data Integrity

The ControlWave Historical Data Collection sys- tem 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 backfilled with the missing data. This distributed his- torical database architecture provides the greatest data reliability and integrity during communication or PC failure.

OPC Server

With industry demand for open standards, ControlWave answers the call by embracing tech- nologies that open the door for maximizing your efficiency and productivity. The OPC standard was developed by the OPC Foundation comprised of hardware and software suppliers from the process control community. OPC allows the engineer to select best in class hardware and software with con- fidence in their interoperability. Our OpenBSI OPC Server was among the first to comply with the OPC Foundation alarm and event server specification.
