The Siemens Industry Automation Division has equipped its modular, sector-independent Simatic WinCC/B.Data energy management system with new functions, as well as support for Microsoft Excel 2010 and Windows 7. The new V5.2 SP1 version features a data connection wizard which facilitates easy and efficient linking of energy measuring points and WinCCarchive tags to B.Data. The wizard also supports data acquisition from such sources as WinCC, OPC or FTP. Installation is significantly faster and easier, as less experienced users are supported by default parameters, a standardized setup process, tooltips, simple configuration, as well as improved documentation. Expert set-up mode offers a greater degree of freedom to more experienced users. The new version not only supports WinCC V7.0 SP2 but also the supervisory control and data acquisition SCADA system, Simatic WinCC RT Professional V11 SP1, which is used to connect the energy management system to the TIA Portal engineering network's runtime system. With the Simatic WinCC/B.Data energy management system, manufacturing companies can optimize their energy costs and transparency at management level, from purchasing to planning and controlling. Seamless energy and materials accounting in power generation and consumption systems enhances energy efficiency and lowers energy costs.
