Note
Migration of a PROFINET ring to a line topology
If you want to migrate a configuration scenario with PROFINET ring into a line topology, note
the following changes:
Remove a ring segment (PROFINET cable) at X1 interfaces of the H-CPUs, e.g., directly
connected PROFINET cable at X1 P2 interfaces.
Change the MRP roles of the H-CPUs and the IO devices to the setting "No device in the
ring".
If necessary, adjust the configured topology. Pay attention to HMI devices that are
connected in the PROFINET ring via the system IP address.
6.3.7.2 Configuration of PROFINET rings with R1 devices
Introduction
The section below shows you the configuration of the S7-1500H redundant system with R1
devices in 2 PROFINET rings.
Advantages/benefits
Communication takes place via two separate PROFINET rings.
As with system redundancy S2, system redundancy R1 enables uninterrupted process data
exchange with the S7-1500H redundant system in the event of a CPU failure.
The redundant system continues to operate in the event of a failure of an interface
module of an R1 device or a line interruption of a PROFINET ring.
