With rising energy awareness and increased requirements regarding user-friendliness and security, recent years have seen building automation facing far-reaching demands.

Bus systems for building management systems, such as KNX/EIB, and a host of available components for these are used for implementing the corresponding systems.

While controllers for the room level are used for local automation, field-proven industrial components like SIMATIC are resorted to in the case of more complex, higher-level automation.

Communication between the automation levels takes place over Ethernet using special KNXnet/IP interfaces.

The KNX/EIB2S7 software package provides blocks for communication between SIMATIC S7 and building automation components. This means message frames of the KNX bus can be processed in a SIMATIC controller.
