Performance segments of redundant CPUs
The CPUs of the S7-1500R/H redundant system offer a high degree of reliability and system
availability. A redundant configuration of the most important automation components
reduces the likelihood of production downtimes and the consequences of component errors.
The higher the risks and costs of a production downtime, the more worthwhile the use of a
redundant system. The avoidance of production downtimes compensates for the generally
higher investment costs.

Performance segments of compact CPUs
The compact CPUs can be used for smaller to mid-range applications and have an integrated
analog and digital on-board I/O as well as integrated technology functions.
