Specific configuration variants for S7-1500H

5.3.3.1

Configuration of line topology with S2 devices and switch

Introduction
The section below shows you the configuration of the S7-1500H redundant system with line
topology, S2 devices and switch. An additional line topology is connected to the switch.
Advantages/benefits
• Less wiring effort required due to the line topology. Only one PROFINET line is connected
to each of the PROFINET interfaces X1 of the H-CPUs.
• A configuration of the MRP rollers is not required.
• No MRP reconfiguration times required and therefore shorter monitoring times possible.
• In the event of a line break in the line topology between the H-CPUs, the S2 device does
not fail.
• The configuration can be expanded with an additional line topology via a switch.
