Overview
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 in production and process
engineering, and it is characterized primarily by its modularity
and performance reserves.
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; user-friendly connections.
• Optimal communication and networking options.
• User-friendly handling and uncomplicated design without a
fan.
• Can be expanded without problems when the tasks increase.
• Multicomputing:
Simultaneous operation of several CPUs in one S7-400 central
controller.
Multicomputing distributes the overall performance power of
an S7-400. For example, complex tasks can be divided into
technologies such as open-loop control, computing or
communication, and assigned to different CPUs. And every
CPU can be assigned its own local I/O.
• Modularity:
The powerful backplane bus of the S7-400 and the communi-
cation interfaces that can be connected direct to the CPU
enable high-performance operation of a host of communi-
cation lines. This enables, for example, division into one
communication path for HMI and programming tasks, one for
high-performance and equidistant motion control compo-
nents, and one for a "normal" I/O fieldbus. Additionally
required connections to MES/ERP systems or the Internet can
also be implemented.
• Engineering and diagnostics:
The S7-400 is configured and programmed extremely
efficiently together with the SIMATIC Engineering Tools partic-
ularly in the case of extensive automation solutions with a high
engineering component. For this purpose, high-level
languages such as SCL and graphical engineering tools for
sequential controls, state graph programs and technology-
oriented diagrams are available, for example.
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.
