4.3.2.3 How to connect singular components to the redundant terminal bus on the basis of the
Parallel Redundancy Protocol
Introduction
You can connect the following non-redundant objects to a redundant network with the
SCALANCE X204RNA .
● Non-redundant networks
● Components that have just one network connection, for example
You will find additional information on this topic in section "Redundant, fault-tolerant terminal
bus based on the Parallel Redundancy Protocol (PRP) (Page 50)".
Procedure
1. Connect the networks for the redundant terminal bus (referred to as LAN A and LAN B
2. Connect the non-redundant objects to the following ports:
3. Configure the SCALANCE X204RNA.
Messages
● SCALANCE X204RNA has signaling contacts.

4.3.3 How to configure a fault-tolerant plant bus
Introduction
You configure the communication connections for the plant bus with NetPro. Industrial Ethernet
is used for the plant bus.
Fault-tolerant plant bus
You can set up a fault-tolerant plant bus with a ring structure.
