Setup and Configuration of a Redundancy via PRP and HSR
https://support.industry.siemens.com/cs/document/78790945/
The enhanced level of automation of industrial plants in order to raise productivity and quality, increases the dependency on the availability of automation systems at the same.
Failure of an automation system can cause high costs due to production failure and downtimes. If Ethernet is used in automation, specific protocols and appropriate hardware have to ensure the availability.
Time and security-critical applications in plants do not tolerate downtime. The implementation of a redundancy without changeover (bumpless) has highest priority here.
The automation task consists in allowing bumpless redundancy for a sophisticated industrial application.

To implement the automation task and to fulfill the mentioned requirements, this application provides two approaches on the basis of the mechanism standardized in IEC 62439-3:
Network redundancy PRP (Parallel Redundancy Protocol) with the SCALANCE X204RNA PRP (EEC), SOFTNET IE RNA and CP443-1 RNA.
Media redundancy HSR (High-availability Seamless Redundancy Protocol) with the SCALANCE X204RNA HSR (EEC).
Redundancy via PRP and HSR Redundancy via PRP and HSR

Redundancy via PRP and HSR Redundancy via PRP and HSR

The advantages of these mechanisms are:
Very high plant availability due to parallel data transfer in ring-shaped or separate network structures.
Application also in time-critical applications due to bumpless switchover.
Possible integration into network management systems.
Fast commissioning without mandatory configuration.

The following main points are discussed in this application:
Basics on PRP and HSR in view of setup, configuration and function.
Setup of a PRP/HSR network with SIMATIC NET components.
Demonstration of redundancy based on a small simulation program.
