6.3.1 S7-1500R/H configuration with IO devices in the PROFINET ring
Introduction
The following sections set out configurations of the S7-1500R/H redundant system with IO
devices in the PROFINET ring.
Advantages/benefits
• IO devices with S2 system redundancy enable uninterrupted process data exchange with
the S7-1500R/H redundant system in the event of a CPU failure.
• The redundant system continues to operate following a cable interruption anywhere in
the PROFINET ring.
