S7 400 PLC Controller offered provides support for mid to high-end performance ranges as well as for most demanding tasks. Featuring support in form of comprehensive range of modules and performance graded CPUs, these allow for optimal adaptation to automation task as well as flexible usage support using simple implementation of distributed structures and support of user-friendly connections. The controllers also come with desired communication and networking option as well as user-friendly handling and uncomplicated design without fan support. Further, these come with powerful backplane bus of S7-400 as well as communication interface that allows direct connection to CPU and allows high-performance operations of host of communication lines.
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.
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 enables, for example, division into one communication path for HMI and programming tasks, one for high-performance and equidistant motion control components, 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 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 graph programs and technology-oriented diagrams are available, for example.
