Configuring Media Redundancy (Mrp) For A Configuration With The Redundant S7-1500R/H System - Siemens SIMATIC ET 200AL System Manual

6.9 Configuring media redundancy (MRP) for a configuration with the redundant S7-1500R/H system

6.9 Configuring media redundancy (MRP) for a configuration with
the redundant S7-1500R/H system
Requirements
• Redundant S7-1500R/H system
• All devices in the ring support the media redundancy protocol MRP.
• IO devices are assigned to the redundant S7-1500R/H system.

MRP role of the CPUs of the redundant S7-1500R/H system
As soon as you create a redundant S7-1500R/H system in STEP 7, STEP 7 automatically assigns
the MRP role "Manager (auto)" to the PROFINET interfaces X1 of both CPUs.
Defining the MRP role for additional devices of the ring in STEP 7
To specify the media redundancy for additional devices in the ring, follow these steps:
1. In the network view of STEP 7, select the PROFINET interface X1 of one of the two CPUs of
the redundant S7-1500R/H system.
2. In the Inspector window navigate to "Properties" > "General" > "Advanced options" > "Media
redundancy".
