Introduction to Siemens SIMATIC S7-400 PLC

10 different CPUs for S7-400.

4 types of CPUs, used for S7-400H and S7-400F/FH.

Three fail safe CPUs can be used for S7-400F, with different performance levels to meet different application areas.

SIMATIC S7-400 Application

SIMATIC S7-400 is a programmable controller designed for the mid to high performance range.

The modular and fanless design, durability, easy scalability and extensive communication capabilities, easily implementable distributed structure, and user-friendly operation make SIMATIC S7-400 the preferred ideal solution in the mid to high end performance control field.

Application areas of SIMATIC S7-400:

General mechanical engineering, automotive industry, three-dimensional warehouse, machine tools and tools, process control, control technology and instrumentation, textile machinery, packaging machinery, control equipment manufacturing, specialized machinery.

The S7-400 series PLC gradually upgrades its functions to multiple levels of CPUs, with a complete range of user-friendly function templates that enable users to form the best solution and meet the requirements of automated tasks. When control tasks become more complex, the control system can be gradually upgraded at any time without adding too many additional templates.

Factory applications of SIMATIC S7-400 CPUs at various levels

The SIMATIC S7-400 can use various CPUs with different performance levels:

CPU 412-1, CPU 412-2, and CPU 412-2 PN: Used for small factories with medium performance.

CPU 414-2、CPU 414-3、CPU 414-3 PN/DP： Used for medium-sized factories with additional requirements for programming, processing speed, and communication.

CPU 416-2, CPU 416-3, CPU 416-3 PN/DP: factories with high requirements in the high-end performance range.

CPU 417-4 DP: A factory with extremely strict requirements within the high-end performance range.

CPU 412-5H, CPU 414-5H, CPU 416-5H, and CPU 417-4H: used for SIMATIC S7-400H and S7-400F/FH.

CPU 414F-3 PN/DP, CPU 416F-2, and CPU 416F-3 PN/DP: used to build fail safe automation systems, suitable for factories with high safety requirements.
