Application

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

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.

• 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

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

• 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).

• Communication processor for connection to TeleControl Server Basic control center software control center software via Ethernet, and for safe communication via IP-based networks.

• Communication processor for connection to control centers for telecontrol applications.

• RF120C for connection to SIMATIC Ident systems.

• Module SM1278 for connecting IO-Link sensors and actuators.

• 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.

• 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.
