Overview

Diagrammatic representation
Representing all SIMATIC controllers, this solution uses an S7-1200 CPU. The
diagrammatic representation below shows the most important components for
communication between an S7-1200 CPU and a KNX network using the "Triple-
X PROFINET + KNX" universal gateway from MBS GmbH.

KNX devices
The "Triple-X PROFINET + KNX" universal gateway enables communication
between an S7-1200 CPU and KNX devices via PROFINET and the KNX bus.
In this example, the KNX devices consist of:

KNX wall switch triple

KNX room control unit

KNX power supply
Correct communication is verified with the KNX devices and a STEP 7 (TIA Portal)
watch table.

An external KNX power supply is necessary for operating a KNX network and is no
communication node in the network.
