5.3.1 Overview of configuration steps
Introduction
After you have inserted all of the components (AS, OS and ES) in your project, you can use
NetPro to configure the network connections between the SIMATIC components. When the
configuration of the connections and network is complete, the configuration needs to be
compiled, saved and downloaded to the CPU of the automation system.
Downloading connection configurations
Connection configurations can be downloaded to the CPU in RUN mode. To do this, select
the connection to be downloaded in NetPro and transfer it to the CPU by selecting the menu
command Target systems > Download > Selected Connections. Process interfacing for
operation stations is not possible until the connections are made known to the AS.
You need to change the MAC addresses after failure of network adapters. You adapt the
addresses in the properties dialog box of the individual operator stations in NetPro. The
configuration has to be compiled and downloaded in NetPro each time it is changed.
Overview
This section describes the configuration steps for the following topics:
● Configuring a redundant, high availability terminal bus
● Configuring a high availability plant bus (Page 117)
● Configuring a redundant PROFIBUS DP (Page 119)
● Configuring a high availability fieldbus based on PROFINET (Page 122)
● Configuring a media-redundant fieldbus based on PROFINET (Page 125)
● Configuring a redundant PROFIBUS PA (Page 128)

Protocol
Introduction
The NetPro and HW Config programs do not support configuration of the terminal bus. The
"SIMATIC NET SOFTNET-IE RNA" software is used in PCS 7 for the connection of a PC
station to separate redundant networks.
