The Web Viewer provides process data to a desktop computer
that is connected to the company LAN/WAN through a direct
connection, or an off-site dial-up or Internet connection.
By using the Internet to deliver plant process data to
any location, the Web Viewer reduces support costs and
reduces response time. On-call support professionals can
troubleshoot plant control systems from any location, without
traveling to the plant.
The Web Viewer makes DCS information both accessible and
portable by using Java™ applets to communicate and transfer
process data from the plant network directly to the desktop.
PCs use Web browsers to dynamically display and update live
Ovation®
process values, process data, graphic displays, and trends
to the desktop computer.
Because access to plant information is read-only, control
functions are disabled and no proprietary hardware or software
is required for the Web Viewer client workstation. Desktop
PCs use a Java-enabled browser to access live DCS data via
the Internet or company intranet.
Web Viewer Features:
- Provides real-time process control data to management,
engineering, maintenance, or administrative personnel-when
and where they need it
- Provides connectivity via the Internet or company intranet
- Provides read-only access to all process data — all
control functions are disabled
- Interfaces with process point database, displaying process
diagrams, live and historical trending, historical point
review and point information
- Converts DCS graphics to Java objects, displaying dynamic,
real-time process point data in HTML-coded web pages
- Supports multiple points of access including an option
for a dial-up, company intranet, or standard Internet connection
- Formats data into custom report styles for quick analysis
and decision-making
