"Overview

S7-400

• The power PLC for the mid to high-end performance ranges.
• The solution for even the most demanding tasks.
• With a comprehensive range of modules and performance-graded CPUs for optimal adaptation to the automation task.
• Flexible in use through simple implementation of distributed structures and extensive communications capabilities.
• User-friendly handling and uncomplicated design without a fan.
• Can be expanded without problems when the tasks increase.

S7-400H

• Fault-tolerant automation system with redundant design.
• For applications with high fail-safety requirements. Processes with high restart costs, expensive downtimes, little supervision, and few maintenance options.
• Redundant central functions.
• Increases availability of I/O: switched I/O configuration.
• Also possible to use I/Os with standard availability: single-sided configuration.
• Hot stand-by: automatic reaction-free switching to the standby unit in the event of a fault.
• Configuration with two separate or one divided central rack.
• Connection of switched I/O via redundant PROFIBUS DP.

S7-400F/FH

• Failsafe automation system for systems with increased safety requirements.
• If required, also fault tolerant through redundant design.
• Without additional wiring of the safety-related I/O:
• safety-relevant communication via PROFIBUS DP with PROFIsafe profile.
• Based on S7-400H and ET 200M with safety modules
• Standard modules for non-safety-related applications can also be used in the automation
