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.
SIMATIC S7-400 process controller: a powerful solution
Part of the SIMATIC process controller series, the S7-400 has been designed for system solutions in the fields of manufacturing and process automation. This process controller is ideal for data-intensive tasks that are especially typical for the process industry. High processing speeds and deterministic response times ensure short machine cycle times on high-speed machines in the manufacturing industry.
The Advanced Controller SIMATIC S7-1500 can be used in the entire automation industry in applications that are medium-sized to high-end machines with high demands on performance, communication, flexibility and technological features. 
Do you want to further utilize the investment into your machine or plant? The well-engineered, proven controller SIMATIC S7-300 will be available at least until 2020. Our 10 years spare part commitment starts thereafter.
