LAN
KNX
Advantages
The solution presented here offers the following advantages:

Easy adaptation to other controller families. Representing all other SIMATIC
controllers with a PROFINET IO interface, this solution uses the S7-1200 CPU.

Easy adaptation when expanding plants. The gateway is configured directly in
the gateway's integrated web server.

Integration of the gateway as a PROFINET IO device via a GSD file.

Gateway as distributed I/O with up to 340 bytes of input and 340 bytes of
output.

Up to 2500 data points possible for communication between PROFINET and
KNX.
Scope

This document does not replace the gateway manual. If there are any
differences in the documentation, the documentation provided by MBS GmbH
always takes precedence.

This application example only describes how to get started with KNX
communication with SIMATIC CPUs using a KNX gateway. For more
information about the KNX gateway, please refer to the gateway manual or
directly contact MBS GmbH.

Configuring the KNX devices using the ETS
between the gateway and the KNX devices are not part of this application
example.

Sales, distribution, training, service and support for the "Triple-
X PROFINET + KNX" universal gateway are provided exclusively by
MBS GmbH.
Required knowledge
