Redundant Media
The RX3i PROFINET Controller module supports PROFINET Media Redundancy Protocol (MRP).
The PROFINET Controller can be used as either a Media Redundancy Manager or Media
Redundancy Client on a redundant media ring.
Media Redundancy enables the network to recover from a network link or switch failure. Because it
operates transparently to applications using the network, no changes to the application are needed
to use media redundancy.
This chapter describes:
 PROFINET Media Redundancy Protocol
 MRP Performance
 Ring Topology with One Controller
 Ring Topology with Multiple Controllers
 Setting Up Media Redundancy Protocol for a PROFINET IO-Controller
 Sequence for Enabling Media Redundancy
 Sequence for Replacing a Media Redundancy Manager
 Procedure for Disabling Media Redundancy
