• 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

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.

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

Communication modules permit communication via point-to-point connections. The RS 232 and RS 485 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.

The SIMATIC S7-1200 Controller is characterized by:

• Easy getting started:
  Special starter packages including simulators and documentation 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.
• Real-time properties:
  Special interrupt functions, fast counters, and pulse outputs permit use even with time-critical processes.

The SIMATIC S7-1200 complies with the following national and international standards:

• UL 508
