WinCC/Web Navigator

Description

The WinCC/WebNavigator provides you with the capability of operating and monitoring your plant via the Internet or the company-internal intranet or LAN without the need for changes to the WinCC project.

This means that the Web Navigator offers the same archive display, operator input and access options as the local operator stations. This also means that the displayed process pictures can contain Visual Basic scripts for dynamic sequences, that you can access WinCC user archives, that the system now supports operator messages on the web client and that the operator stations on the Web are integrated into user management.

Benefits

• Operator control and monitoring over long distances with up to 50 operator stations simultaneously

• Fast update rates due to event-driven communication

• Optimally tailored clients for operating and monitoring, analysis, service and diagnostics

• Thin client solutions on different platforms (PC, onsite panel, mobile PDA)

• Web and terminal clients can be added whenever required

• Minimum maintenance costs due to central software administration

• Acceptance of configuration data for the web, generally without changes

• Increased security and availability due to separation of WinCC and web server

• Granting access rights using plant-wide user administration

• High Internet security standards

Functionality

New application areas

In addition to the typical use of the WinCC/WebNavigator in WANs (Wide Area Networks), the WinCC/WebNavigator can also be used for applications that must be implemented at minimal cost. This especially includes applications that have a pronounced distributed structure (e.g. water/wastewater), or in which access to process information is only sporadic (building management). In addition to this, web clients can also be used as normal operator stations on the LAN.

Web server and clients

For a web solution, the WebNavigator is installed on a WinCC single-user system or server and a WebNavigator client is set up on any Windows PC. This allows a running WinCC project to be operated and monitored via MS Internet Explorer, or via terminal services, without the need for a WinCC basic system on the computer.

It is also possible to use the web client without MS Internet Explorer; the visual appearance corresponds to the standard client. Such a web server can also be set up on each WinCC (SCADA) client. This means that a web client that is connected to the web server can access the projects of all (up to 12) redundant WinCC servers in a plant from anywhere in the world. The projects can be displayed simultaneously in different tabs, e.g. via the multi-tabbing functionality of MS Internet Explorer V7.In this case, the web client also switches transparently between redundant, lower-level WinCC servers. If the browser is started several times on the web client, it is even possible to simultaneously view several plants, i.e. also several web servers.
