Siemens WinCC/Web Monitor Provides Operator Control and Monitoring Via the Web

The Siemens Industry Automation Division has introduced the WinCC/Web Navigator. It provides users the capability of operating and monitoring plants via the Internet, company-internal intranet, or LAN, without requiring changes to a WinCC project.

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

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

Key benefits of the WinCC/Web Monitor include:

• 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, monitoring, analysis, service, and diagnostics
• Thin client solutions on different platforms (PC, onsite panel, mobile PDA)
• Web and terminal clients 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
