Siemens Introduces SIMATIC WinCC 7.4

Siemens has introduced SIMATIC WinCC 7.4, the newest version of the scalable and open SCADA system for maximum plant transparency and productivity. Due to the increasing globalization of business and rising competition, it is more advantageous to gain a shorter time-to-market. However, companies are forced to reduce machine downtime and to grow the quality of their products. The production data that is generated has to be available from the shop floor to the ERP, every time, from anywhere.

Configuration Studio and Graphics Designer. With the Graphics Designer, the WinCC Configuration Studio is the central development platform for WinCC applications. By using the integrated scripting and programming interfaces, it is possible to automate many engineering processes and to integrate individual runtime functionalities. Additional function extensions make it possible to process mass data very fast and to integrate standardized application modules in any part of your application. The optimization of the interaction between the Configuration Studio and the Graphics Designer enables you to develop your applications faster. As a result, you can increase the engineering efficiency and therefore gain a shorter time-to-market. Features include:

  • Drag and drop between configuration studio and graphics designer
  • Search and replace for pre- and post-fixes
  • VBA support for the configuration studio
  • Preview of WinCC screens in the WinCC explorer
  • Display of analog alarms in the online trend control

WinCC/WebUX. This WinCC Client was developed simultaneously with WinCC V7.4. It is a mobile platform and browser independent client with no need of installation on the client side. It is designed for operation on conventional, consumer-type devices. This option enables access to your plant from everywhere, any time. The data privacy is guaranteed by the encryption of an https-connection using SSL. Because of the further development of this option in WinCC V7.4, the functionality is more like the graphics on the server side. Features include:

  • Support of additional controls
  • VB—actions on objects
  • Base functionality of the “Dynamic Dialog”
  • SIMATIC logon for the user administration
  • System messages during Login and Logout
  • One WebUX Monitoring Client included in WinCC V7.4 at no cost
