Bristol® ControlWave® PAC

Key-Lock Security

The front panel keyswitch on ControlWave provides a high level of manual security by allowing three modes of operation to restrict access ot on-line functions.

In Run Mode, ControlWave will reject any attempt to download or modify the running program, either locally or over the network.

In Remote Mode, ControlWave will allow download- ing and on-line program modification through the network provided the security access requirements have been met. Local download and on-line modifi- cation of the running program is prohibited.

In Local Mode, ControlWave will allow download and on-line modification through either the network connection or through a local serial communica- tion port provided the security access requirements have been met.

Multi-User Security Access

Security is an essential element of any open system, particularly those with Internet access. ControlWave employs a User Name/Password ac- cess system protected by a 56-bit encryption tech- nique through the TCP connection. There can be up to thirty-two users who sign in using their name and password. Both the name and the password can be up to sixteen characters.

The security system provides for up to sixty-four access rights to read and write data values and files via FTP, access and configure historical and audit data information, edit configuration, run internal diagnostics, read and reset system status. It further allows the programming software to read, write and download the ControlWave.

The Secure Data Advantage

ControlWave sets a new standard for providing in- telligent control at the point where control is needed. Whether you need control on the plant floor or at a remte site in the "middle of nowhere", ControlWave is the solution for control, communication and secure data to help you make the right operating decisions.

ControlWave was designed to provide the optimum level of data security using a distributed database architecture. All data including time & date stamped alarms, alarm limits, and historical data are stored locally in each industrially rugged ControlWave, thereby distributing your data integrity risk. To firther ensure that the data is always current and historically accurate, the historical data is stored

in non-volatile flash memory within ControlWave. Historical data is even maintained during and after program downloading.

When historical data is collected from ControlWave, it is converted and appended to .CSV and/or ODBC compliant databases but does not destroy the origi- nal historical data stored in ControlWave, thus pro- viding a flexible and secure historical data system that is clearly recognized as a benefit to virtually every industrial application.

The Bridge Between Systems

Continuing our tradition of introducing innovative new solutions while maintaining compatibility with existing systems, Emerson again provides a migra- tion path for existing customers by bridging the new ControlWave system with Network 3000 systems already in place. The network bridge is enabled by employing the open architecture technologies afforded by TCP/IP and OPC in both networks. TCP/IP allows seamless Ethernet connectivity to both networks as well as the corporate Intranet so both ControlWave and Network 3000 controllers can reside and communicate on the same LAN. Em- erson’s Bristol OpenBSI OPC Server facilitates the merging of the two networks for technical, engineer- ing and operator data access. The data source, configuration and path are completely transparent to the OPC client. Real-time data can also be passed between the two communication networks, making this a total Plant Automation Management Solution.
