Introduction
The following section describes the PROFINET IO functions for field of application, properties
and configuration in STEP 7.
Refer to the documentation for the respective device to see to what extent the PROFINET
devices support the described functions.
You can find a tabular overview of the PROFINET devices and the functions these support on
the Internet ( https://support.industry.siemens.com/cs/ww/en/view/102325771 ).
5.1 Connecting other bus systems
Fieldbus integration
PROFINET allows you to use a proxy-capable PROFINET device to integrate existing fieldbus
systems (for example, PROFIBUS, AS interface). The devices of these fieldbus systems are
mapped on proxy PROFINET devices. In this way, you can set up any hybrid systems
consisting of fieldbus and Ethernet-based subsystems. This allows a continuous exchange of
information.
