S7-400 - Programmable Logic Controller
The S7-400 is the most powerful PLC in the family of SIMATIC controllers. It enables successful automation solutions with Totally Integrated Automation (TIA). The S7-400 is an automation platform for system solutions that focuses on process engineering and is characterized primarily by its modularity and performance reserves.
Features
Conformal coating (G3) as standard for increased resistance to environmental influences
High-availability 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.
Redundantly designed central functions
Increases availability of I/O: switched I/O configuration
Also possible to use I/Os with standard availability: single-sided configuration
Can be used with versatile, scalable SIMATIC ET 200SP HA I/O system via STEP 7
Hot standby: Automatic reaction-free failover to the standby unit in the event of a fault
Configuration with 2 separate or one divided central device
Connection of switched I/O via redundant PROFIBUS DP or system-redundant
