Powerful – Fault tolerant – FailsafePart 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. S7-400 and the innovated S7-410 product line will stay the hardware backbone of the PCS 7 control system. For standard and failsafe applications within factory automation the new S7-1500 controller generation takes full advantage of all TIA Portal features.

Information on product lifecycleSelection of the appropriate hardware in process automation is determined by the automation task, the application and the performance required. The flexibly configurable SIMATIC S7-400 controller series designed by Siemens is suitable for demanding applications in the process industry. Here, in particular SIMATIC S7-400H and FH systems are used, which ensure a high degree of security and availability.

SIMATIC S7-400 controllers stand for long-term security of investment. For this reason, Siemens has systematically further developed the SIMATIC S7-400 series. In this way, they ensure that the right controller will always be available for a vast range of automation solutions in the process industry.

Through a long-term supply of spare parts and availability of components, we provide plant operators and constructors permanent access to the SIMATIC S7-400 controller series.

Your step into the future – Migration made easySIMATIC S7-300 and S7-400 are and remain fully developed, proven controllers. Many new requirements regarding handling and performance can no longer be fully met with the traditional architecture. This has led to the development of the next generation of S7-1500 controllers with improved system properties. The basic SIMATIC properties have been retained for compatibility.
