The SIMATIC S7-1200 is the controller for open-loop and closed-loop control tasks in mechanical equipment manufacture and plant construction.

Due to the compact modular design with a high performance at the same time, the SIMATIC S7-1200 is suitable for a wide variety of automation applications. Its range of use extends from the replacement of relays and contactors up to complex automation tasks in networks and within distributed structures.

The S7-1200 also increasingly opens up areas for which special electronics was previously developed for economical reasons.

Application examples include, for example:

  • Placement systems

  • Conveyor systems

  • Elevators and escalators

  • Material transportation equipment

  • Metalworking machinery

  • Packaging machines

  • Printing machines

  • Textile machines

  • Mixing systems

  • Freshwater treatment plants

  • Wastewater treatment plants

  • External displays

  • Electricity distribution stations

  • Room temperature control

  • Heating/cooling system control

  • Energy management

  • Fire protection systems

  • Air conditioning

  • Lighting control

  • Pump control

  • Security/access control systems


The SIMATIC S7-1200 family consists of the following modules:

  • Compact controllers with graded performances in different versions as wide-range AC or DC controllers.

  • Signal boards (analog and digital) for low-cost modular controller expansion directly on the CPU, with retention of the mounting space.

  • Different digital and analog signal modules.

  • Different communication modules and processors.

  • Ethernet switch with 4 ports for implementation of many different network topologies

  • SIWAREX weighing systems terminal module

  • PS 1207 stabilized power supply units, line voltage 115/230 V AC, rated voltage 24 V DC

Mechanical features

  • Rugged, compact plastic enclosure

  • Easily accessible connection and control elements, protected by front flaps

  • Removable connection terminals, also for analog or digital expansion modules

Device features

  • International standards: 
    SIMATIC S7-1200 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 S7-1200 is equipped with different communication mechanisms:

  • Integrated PROFINET IO controller interface

  • Communication module with PROFIBUS DP master interface

  • Communication module with PROFIBUS DP slave interface

  • GPRS module for connection to GSM/G mobile phone networks

  • LTE module for communication in mobile phone networks of the fourth LTE generation (Long Term Evolution).

PROFINET interface

The integral PROFINET interface permits communication with:

  • Programming device

  • HMI devices

  • Other SIMATIC controllers

  • PROFINET IO automation components

The following protocols are supported:

  • TCP/IP

  • ISO-on-TCP

  • Field PG programming device and PCs via standard CAT5 cable.

Connection between PG and CPU of SIMATIC S7-1200

  • SIMATIC HMI Basic Panels

Connection between Basic Panel and CPU of SIMATIC S7-1200

  • Further SIMATIC S7-1200 controllers

Connection of several devices via CSM 1277 Ethernet switch

Point-to-point interface, freely-programmable interface mode

Communication modules permit communication via point-to-point connections. The RS232 and RS485 physical transmission media are used. Data transmission is carried out in the "Freeport" mode of the CPU. A user-specific, bit-oriented communication protocol is used (e.g. ASCII protocol, USS, or Modbus).

Any terminal equipment with a serial interface can be connected, e.g. drives, printers, bar code readers, modems, etc.
