The Power Controller for system solutions in the manufacturing and process industries
Within the Controller family, the SIMATIC S7-400 is designed for system solutions in the manufacturing and process automation.
The product range comprises 9 Standard CPUs, 2 failsafe and 2 high available CPUs.

The following features make the SIMATIC S7-400 the most powerful Simatic PLC:
The S7-400 is especially suitable for data-intensive tasks in the process industry. High processing speeds and deterministic response times guarantee short machine cycle times on highspeed machines in the manufacturing industry. The highspeed backplane bus of S7-400 ensures efficient linking of central I/O modules. 
The S7-400 is used preferably to coordinate overall plants and to control lower-level communications lines with slave stations; this is guaranteed by the high communication power and the integral interfaces. 
The power of the S7-400 is scalable thanks to a graded range of CPUs; the capacity for I/O is almost unlimited. 
The power reserves of the CPUs enable new functions to be integrated without further hardware investment, e.g. processing of quality data, user-friendly diagnosis, integration into higher-level MES solutions or high-speed communication via bus systems. 
The S7-400 can be structured in a modular way without any slot rules; there is a widely varied range of modules available both for centralized configurations and distributed structures. 
The configuration of the distribuded I/O of the S7-400 can be modified during operation. In addition signal modules can be removed and inserted while live (hot swapping). This makes it very easy to expand the system or replace modules in the event of a fault. 
The storage of the complete project data including symbols and comments on the CPU simplifies service and maintenance calls 
Safety technology and standard automation can be integrated into an S7-400 controller; the plant availability can be increased by the redundant set-up of the S7-400
Many of the S7-400 components are also available in a SIPLUS version for external environmental conditions, e.g. extended temperature range (-25?+60°C) and for use where there is aggressive atmosphere/condensation.
