S7-400

SIEMENS

 

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

There is a graded range of CPUs from the entry-level CPU right up to the high-performance CPU for configuring the controller. All CPUs control large quantity structures; several CPUs can work together in a multicomputing configuration to boost performance. Thanks to their high processing speed and deterministic response times, the CPUs enable short machine cycle times.

The different CPUs are distinguished by, for example, work memory, address range, number of connections and execution time. As well as the standard CPUs, there are also two failsafe and three fault-tolerant CPUs available.

With the new Version 7 the continuous advancement of the series will be continued. Among others, storage, performance and quantity structure have been innovated. Furthermore the focus was on the new expansion of the Profinet communication performance. The complementary systems are still the high-end controller for all industries.


Features

  • 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 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).
  • 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.
