The S7-400 is the most powerful PLC in the family ofSIMATICcontrollers. It enables successful automation solutions withTotally Integrated Automation (TIA). The S7-400 is an automation platform for system solutions in production and process engi- neering, 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.

   Programmable logic controller (PLC) is a control system using electronic operations. Its easy storing procedures, handy extending principles, functions of sequential/position control, timed counting and input/output control are widely applied to the field of industrial automation control.
