How to configure a fault-tolerant fieldbus on the basis of PROFINET
Introduction
The following section describes how to create and connect a fault-tolerant fieldbus on the basis
of PROFINET.
● Configure the components in the HW config.
● In the Topology Editor, configure the connections between the components in accordance
Requirements
● The PCS 7 project with a SIMATIC H station is open in SIMATIC Manager.
● HW Config is open.
● The redundant backplane is inserted in HW Config.
● In HW Config, each rack has been fitted with an 4xx-xH PN/DP H CPU and the required
● The PROFINET IO systems are added to the H-CPU. This can be done using Insert on the
