MRP ring with SIMOCODE and SIMATIC S7-1500
https://support.industry.siemens.com/cs/document/109742280/configuration-of-an-mrp-ring-with-simocode-and-simatic-s7-1500
To ensure high plant availability, the devices are connected with each other in an MRP ring (Media Redundancy Protocol). As a result, the remaining devices are still accessible in the event of a device or line failure.

The “Media Redundancy Protocol” (MRP) is a protocol for high-availability networks that are usually required for critical automation applications.
By establishing a ring topology, single failures of a switch or a line can be compensated with MRP.
In an MRP ring, a redundancy manager (in this application example the SIMATIC S7-1500) sends aparte test packages and checks, whether the ring is closed.
If an MRP ring component fails, the test packages sent by a port do not reach the respective other port. The redundancy manager then informs the switches about the altered topology and forwards their packages to both directions.

In addition to the MRP ring, the PROFINET function “Device replacement without removable medium/PD” is used in this application example. If a device is exchanged, the IO controller automatically assigns configured parameters to the new device. Therefore, the service personal does not need to load the configuration into the new device and downtime is reduced.

Configuring bumpless redundancy with 'MRPD'
https://support.industry.siemens.com/cs/document/109744035/
High availability through configuration of a bumpless media redundancy in ring topology with MRPD
For some applications, the reconfiguration time (200ms for 50 devices) of MRP does not suffice for real-time processes. For this purpose, there is the real-time-capable media redundancy process MRPD.

In this respect, the following challenges need to be considered:
Safe communication between the participants of the ring.
Short update time of the PROFINET devices.
The concept needs to be applicable for an IRT network.
During interruptions or a device exchange, no data loss must occur.

MRPD offers the following advantages:
Short update times through IRT.
During a device or line failure in the ring, all other devices continue to be supplied with IO data without interruption and without reconfiguration time.
Manufacturer-independent, as MRPD is specified by the PROFINET standard.
Comprehensive diagnostics via PROFINET.
Without the use of additional external Ethernet Switches.
