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. What's 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.
