Media redundancy
Media redundancy is a function that ensures network and system availability. Redundant
transmission links in the MRP topology ensure that an alternative communication path is
made available if a transmission link fails. To make this possible you need to configure the
readers as a clients of the Media Redundancy Protocol (MRP) in STEP 7 (Basic / Professional).
MRP is part of PROFINET standardization according to IEC 61158.
Setup of an MRP ring topology
To set up an MRP ring topology with media redundancy, you must join both free ends of a
line topology in the same device. The closing of the line topology to form a ring is via two
network ports of one of the devices (ring ports). The readers can be integrated as clients in an
MRP ring topology via the network ports "X1P1R" and "X1P2R".
You will find additional information on setting up an MRP ring topology in the STEP 7 online
help and in the "SIMATIC PROFINET system description
