SIMATIC S7-400 SIEMENS PLC CONTROLLER CPU PROCESS

• S7-400:
  The power PLC for the mid to high-end performance ranges with modular, fan-free design.
• S7-400H:
  Fault-tolerant automation system with redundant design for fail-safe applications.
• S7-400F/FH:
  Fail-safe automation system with redundant design that can also have high availability.

S7-400

The S7-400 automation system is modular in design. It has a comprehensive range of modules that can be combined individually.

A system includes the following:

• Power supply module (PS):
  for connecting the SIMATIC S7-400 to a supply voltage of 120/230 V AC or 24 V DC.
• CPUs:
  Different CPUs with integral PROFIBUS DP interfaces are available for different performance ranges. Depending on type, they are also available with integral PROFINET interface. The PROFIBUS interface enables the connection of up to 125 PROFIBUS DP slaves. Up to 256 PROFINET IO devices can be connected to the PROFINET interface. All CPUs of the SIMATIC S7-400 can handle extremely large configurations. In addition, several CPUs can work together in multicomputing in one central controller to increase performance. The CPUs enable short machine cycle times by means of their efficient processing speed and deterministic response times.
• Signal modules (SMs) for digital (DI/DO) and analog (AI/AO) input/output
• Communications processors (CPs), e.g. for bus connection and point-to-point connections
• Function modules (FMs):
  The specialists for demanding tasks such as counting, positioning and cam control.

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.
