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
- Pump control
- Security/access control systems
- 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.

Function
The S7-1200 is characterized by:
- Extremely simple starter solution:
Special starter packages and introductions facilitate familiarization. - Uncomplicated operation:
Powerful standard commands which are simple to use, together with the user-friendly programming software, reduce the programming overhead to a minimum. - Exceptional real-time characteristics:
Special interrupt functions, fast counters, and pulse outputs permit use even with time-critical processes.
The SIMATIC S7-1200 meets national and international standards:
- UL 508
- CSA C22.2 No. 142
- FM Class I, div. 2, group A, B, C, D; T4A Class I, Zone 2, IIC, T4
- VDE 0160
