SIMATIC S7-400 : The most powerful Automation System within SIMATIC
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.
SIMATIC S7-400 : 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.
Standard mechanical equipment manufacture, including custom mechanical equipment manufacture
Power generation and distribution
Paper and printing industries
Food, beverages and tobacco industries
Process engineering, e.g. water and wastewater utilities
Chemical industry and petrochemicals
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; there is a widely varied range of modules available both for centralized configurations and distributed structures. This results in very cost-effective spare parts handling.
The configuration of the distributed I/O of the S7-400 can be modified during operation (Configuration in Run). 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 engineering and standard automation can be integrated into a single S7-400 controller; plant availability can be increased through the redundant structure 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.
The high-speed backplane bus of S7-400 ensures efficient linking of central I/O modules
