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

(https://support.industry.siemens.com/cs/ww/en/view/19292127)".
