5.1.1 Areas of application
Objective
The S7-1500R/H redundant system offers a high degree of reliability and system availability. A
redundant configuration of the most important automation components reduces the
probability 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. You can compensate for the generally higher investment costs by
avoiding production downtimes.
Use
In redundantly operated systems, failure or malfunction of individual automation
components must not impede the operation of the plant. S7-1500R/H redundant systems are
used in the following areas, for example:
• Tunnels
• Airports (for example baggage conveyors)
• Subways
• Shipbuilding
• Wastewater treatment plants
• High-bay warehouse
