Reducing costs and increasing efficiency in building automation


Vendor-independent and object oriented; the common factor between the building automation communications protocol BACnet and the SCADA system SIMATIC WinCC Open Architecture. The WinCC OA BACnet package unites building control system and superordinated SCADA system. Offering direct access to the automation level, making WinCC OA BACnet the ideal solution for managing large and/or distributed facilities and properties.

Centralized operations and integration of all systems is a significant prerequisite for satisfying the efficiency and energy provision demands of facility and property management. The development of WinCC OA BACnet, a native BMS solution, addresses a wide spectrum of such customer requirements and demands. As WinCC OA BACnet is designed for an unlimited number of BACnet objects, and is especially suitable for complex projects in industry, airports, universities, hospitals, trade fairs etc.
A further advantage is that WinCC OA BACnet run both under Windows and Linux systems.

In comparison with island solutions, the virtually seamless compatibility between SIMATIC WinCC Open Architecture and BACnet is the major advantage of the tool. Connected to the automation level network WinCC OA BACnet recognizes all BACnet objects existing in the network through the WinCC OA BACnet browser and automatically creates these in SIMATIC WinCC Open Architecture, meaning the data is only present once in the system and can be efficiently processed online, offline or in mixed operation using a quick and efficient engineering toolkit.

The WinCC OA BACnet EDE importer with version management offers direct online data import from BACnet. Furthermore, with WinCC OA BACnet functional differences between individual device profiles are equated in SIMATIC WinCC Open Architecture on the application level. WinCC OA BACnet supports a multitude of BACnet services such as data sharing, scheduling, device and network management as well as alarm and event notification; trending is also available as an option.

WinCC OA BACnet not only fulfills the BACnet vision, rather also offers a higher degree of functionality and efficient engineering compared with other conventional SCADA approaches.

Security information

To ensure the secure operation of a plant or machine it is also necessary to take suitable preventive action (e.g. cell protection concept) and to integrate the automation and drive components into a state-of-the-art holistic industrial security concept for the entire plant or machine. Any third-party products that may be in use must also be taken into account. Please find further information at:
