SIMATIC WinCC
Consistently scaleable - even via the web

In general, you don't create automation and IT solutions that are never going to be changed. Rather, they are subject to continuous changes that are implemented on a step-by-step basis. This includes, for example, modernizing individual plant areas, retrospective extensions to plants, implementing central monitoring of different sites in a company and optimizing process sequences at a Site or in a company.

To be able to cope with growing requirements, you must be able to extend process visualization at any time without breaking with the original technology or needing to carry out complete reconfiguration. This means that security of investment is of the essence. SIMATIC WinCC offers the required consistent scaleability, from a single-user solution right through to a client/server solution with integrated Historian and operator stations on the Web

The server option allows you to set up coordinated operator stations from single-user systems at any time.Consistent scalability now uses up to 12 WinCC servers and 32 WinCC clients per server. If required, you can also configure these servers as a distributed system. Distributing the complete application or the tasks to several servers makes possible a much higher performance profile, takes the load off the individual servers and ensures good performance. Distribution also takes intoaccount the topology of a plant.

The complete view of the plant is implemented using WinCC (SCADA) clients that have access to or a view of the pictures and data of different server projects at the same time. It is even possible to use clients for online configuration.You can configure a common message and trend view of the archives of different servers for these clients.

Operation and Monitoring without limits

You can also extend the solution across the local network (LAN) of a site; regardless of whether you only want to be able to remotely monitor a plant area on a sporadic basis (for example in sewage plants or in station supervisory systems) or to be able to access current or historical process information (for statistical evaluations) from anywhere you want.

WinCC/Web Navigator supports full Operation and Monitoring via the Web – without needing to make changes to the project. In Version 6.0, you can set up a Web server on any SCADA client to establish a data concentrator. This means that a Web client that is connected to the Web server can access the projects of all the (redundant) WinCC servers (up to 12) in a plant from anywhere in the world.

With Thin Client solutions , you can also link robust local units (e.g.SIMATIC MP370 with the Thin Client MP option) and mobile clients Personal Digital Assistants (PDAs) under Windows CE.
Solutions of this type make minimal requirements of the hardware,since the application itself runs on the terminal server.

High availability due to redundancy

When you have high availability requirements (minimizing non-productive time), WinCC also provides the right concepts:

• Redundant server with the WinCC/Redundancy option
• Redundant process communication via S7-REDCONNECT
