The most powerful Automation System within SIMATIC
Superb communication capability and integrated interfaces make the SIMATIC S7-400 process controller ideal for larger tasks such as the coordination of entire systems. The graded range of CPUs enables scalable performance and the capacity for I/O periphery is virtually unlimited. Whats more, process controller signal modules can be inserted and removed while the system is live (hot swapping), making it very easy to expand the system or replace modules.
"The multi-facetted module range of S7-400 allows modular customization to suit the most varied tasks.
Apart from the CPUs with integrated functions and interfaces, there is a wide range of special modules in S7-400 design for technolog"
Communication processors are used for connecting S7-400 to the different bussystems / communication networks as well for point-to- point link
