SIEMENS SIMATIC S7-400 Introduction

SIEMENS PLC S7-400, as the part of the SIEMENS PLC SIMATIC process controller series, it 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.

SIEMENS PLC S7-400,is the most powerful PLC in the family of SIMATIC controllers. It enables successful automation solutions with Totally Integrated Automation (TIA). The S7-400 is an automation platform for system solutions that focuses on process engineering and is characterized primarily by its modularity and performance reserves.

SIEMENS SIMATIC S7-400 Feature


  • 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.

The SIMATIC S7-400 is the power PLC for the mid to high-end performance ranges.

The modular and fan-free design, high level of expandability, extensive communication and networking options, simple implementation of distributed structures, and user-friendly handling make the SIMATIC S7-400 the ideal solution even for the most demanding tasks in the mid to high-end performance ranges.

Application areas of the SIMATIC S7-400 include:

  • Automotive industry, e.g. assembly lines

  • Mechanical equipment manufacture, including special mechanical equipment manufacture

  • Warehousing technology

  • Steel industry

  • Building management systems

  • Power generation and distribution

  • Paper and printing industry

  • Woodworking

  • Process engineering, e.g. water and wastewater utilities

  • Chemicals industry and petrochemicals

  • Instrumentation and control

  • Packaging machinery

  • Pharmaceutical industry

Several performance-graded CPU classes and a comprehensive range of modules with a host of user-friendly functions allow users to perform their automation tasks individually.

In the case of task expansions, the controller can be expanded at any time without significant cost by means of additional modules.

The SIMATIC S7-400 is universal in use:

  • Maximum suitability for industry thanks to high electromagnetic compatibility and high resistance to shock and vibration.

  • Modules can be connected and disconnected while power switched on.

S7-400H

In many areas of automation technology, demands are increasing all the time with regard to the availability and thus the fail-safety of the automation systems. There are areas where a plant standstill can result in extremely high costs. Here, only redundant systems can do justice to the availability requirements.

The fault-tolerant SIMATIC S7-400H meets these requirements. It continues to operate even when parts of the controller have failed due to one or more faults. The availability achieved in this way makes the SIMATIC S7-400H especially suitable for the following application areas:

  • Processes with high restart costs after a controller failure (generally in the process industry).

  • Processes with expensive standstill times

  • Processes involving valuable materials, e.g. in the pharmaceuticals industry.

  • Unsupervised applications

  • Applications with reduced maintenance personnel
