Connecting PROFIBUS to PROFINET

PROFIBUS can be integrated in PROFINET. In this way, you can set up any hybrid systems
consisting of fieldbus and Ethernet-based subsystems. This provides a continuous data
exchange.
Coupling of PROFIBUS and PROFINET
With a proxy-capable PROFINET device that is equipped with a PROFIBUS interface in
addition to a PROFINET interface, you can integrate existing PROFIBUS configurations into
the PROFINET configuration.

PROFINET device with proxy functionality
The PROFINET device with proxy functionality is the substitute for a PROFIBUS device on
Ethernet. The proxy functionality allows a PROFIBUS device to communicate not only with
its master but also with all devices on PROFINET.
With PROFINET, existing PROFIBUS systems can be integrated into the PROFINET
communication with the aid of an IE/PB link. The IE/PB link PN IO then handles
communication via PROFINET on behalf of the PROFIBUS components.
