interconnection
Introduction
The section below shows you the configuration of the S7-1500H redundant system with R1
devices and switches with MRP interconnection in a PROFINET ring.
Advantages/benefits
• Redundant data exchange via four or more MRP rings with R1 devices is possible via
switches and MRP interconnection.
• Communication via the R1 devices connected with MRP interconnection takes place via
two separate PROFINET rings.
• 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, regardless of the
location.
