Increasing system availability

The S7-400H automation system satisfies the high demands on availability, intelligence and
distribution put on state-of-the-art automation systems. The system provides all functionality
required for the acquisition and preparation of process data, including functions for the
open-loop and closed-loop control and monitoring of assemblies and plants.
Totally integrated systems
The S7-400H automation system and all other SIMATIC components, such as the
SIMATIC PCS7 control system, are harmonized. The totally integrated system, ranging from
the control room to the sensors and actuators, is implemented as a matter of course and
guarantees maximum system performance.

Graduated availability by duplicating components
The redundant structure of the S7-400H ensures availability at all times. This means all
essential components are duplicated.
This redundant structure includes the CPUs, the power supply modules, and the hardware
for linking the two CPUs.
You yourself decide on any other components you want to duplicate to increase availability
depending on the specific process you are automating.
