SIMATIC S7-400

 


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 that focuses on process engineering and is characterized primarily by its modularity and performance reserves.

•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 of an S7-400. For example, complex tasks in technologies such as open-loop control, computing or communication can be split 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 communication interfaces that can be connected direct to the CPU enable high-performance operation of a host of communication lines. This permits, for example, the division into one communications line for HMI and programming tasks, one line for high-performance and equidistant motion control components, and one "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 particularly 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 graphs and technology-oriented diagrams are available, for example.

• 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: singlesided
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 or
via system-redundant PROFINET IO.
