Miêu tả



The SIMATIC S7-200 is the micro PLC for open-loop control and closed-loop control tasks in machine and plant construction. It combines the greatest possible automation effect with the lowest costs.

SIMATIC S7-200 applications range from replacing relays and contactors to handling complex automation tasks in standalone mode, in networks and within distributed configurations.

To save costs, the S7-200 is increasingly being employed in areas that previously required special electronics.

Applications include:

  • Baling presses
  • Plaster and cement mixers
  • Ventilation plants
  • Centralized/flange lubricating systems
  • Woodworking machinery
  • Gate controls
  • Hydraulic lifts
  • Conveyor systems
  • Food and beverage industry
  • Laboratories
  • Modem applications (remote monitoring and maintenance)
  • Electrical installations


The SIMATIC S7-200 family consists of the following modules:

  • 5 basic devices with graded performances in different versions.
  • 15 different digital and analog expansion modules.
  • 2 communications processors for connection to PROFIBUS and AS Interface.

Mechanical features

  • Rugged, compact plastic housing.
  • Easily accessible connection and control elements, protected by front flaps.
  • CPU 224 and higher: Removable connection terminals, also for digital expansion modules.

Equipment features

  • International standards: 
    SIMATIC S7-200 complies with the standards according to VDE, UL, CSA and FM (Class I, Category 2; Danger zone groups A, B, C and D, T4A). The quality management system used during production is certified according to ISO 9001.

The SIMATIC S7-200 provides various possibilities for communication:

  • Communication interface: 
    Can be operated in PPI slave, MPI slave and in the freely-programmable interface mode.
  • Connection to AS-Interface: 
    As master via CP 242-2 communications processor.
  • Connection to PROFIBUS DP as slave: 
    Via PROFIBUS-EM 277.

PPI network

PPI is the communication system integrated in every S7-200 CPU. Connections for programming, operation or monitoring can be established over a common two-wire cable. The CPUs can communicate simultaneously with several CPUs, TDs or OPs. Data transmission rates 9.6, 19.2 and 187.5 Kbit/s.

The following can be connected:

  • Programming devices: Field PG, Power PG.
  • PCs (AT-compatible), via PC/PPI cable.
  • TD 200 Text Display, TP070 Touch Panel; SIMATIC Operator Panels.
  • SIMATIC S7-200: 
    Max. 31 S7-200 PLCs on a common data line to a PG, PC, TD 200 or OP. Direct data exchange between S7-200 PLCs (in each case as master) and NETR and NETW
