Application

The SIMATIC S7-1200 is the controller for open-loop and closed-loop control tasks in mechanical equipment manufacture and plant construction. It combines maximum automation and minimum cost.

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

Design

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.
    Communication modules (RS232/RS485) for communication via point-to-point connection.
    Communication modules for connection of the controller as a PROFIBUS DP master or PROFIBUS DP slave.
    Communication processors for connection of the controller to mobile phone networks.
    Ethernet switch with 4 ports for implementation of many different network topologies
    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.

Communication

The SIMATIC S7-1200 is equipped with different communication mechanisms:

    Integrated PROFINET IO Controller interface
    Point-to-point connection via communication modules

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
    S7 communication

The following can be connected:

    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.
