6.3.2 Configuration of S7-1500R/H with switches and additional line topology
Introduction
The following sections set out configurations of the S7-1500R/H redundant system with
switches and additional line topology.
Benefits/advantages
• You can use a switch to add an additional line topology to the PROFINET ring. Unlike the
PROFINET ring, the line topology is not redundant.
• PROFINET IO devices can be located in the PROFINET ring or they can be separated with a
switch.
