S7-1200

SIMATIC S7-1200 Controllers are the intelligent choice for compact automation solutions with integrated IOs, communication functions and technology functions for automation tasks in the lower to middle performance range. They are available in standard and fail-safe versions.

The scalable SIMATIC S7-1200 Controllers have integrated inputs and outputs as well as communication options and allow modular expansion. Digital and analog input and output modules as well as different communications and special modules enable flexible adaptation to the relevant automation task.

Efficient engineering

• The seamless integration of SIMATIC Controllers into the common TIA Portal engineering framework permits the integrated storage of data, the smart library concept, and a uniform operating philosophy. This makes the use of universal functions particularly easy.

Variety of diagnostic options

• An efficient error analysis and fast error localization with the new uniform display concept – plain text information on the error message in TIA Portal, on the HMI, and in the web server – shortens commissioning times and minimizes production downtimes. SIMATIC S7-1200 offers you a diagnostic functionality that is already integrated in the system, without the need for any further programming.

Innovative design

• The SIMATIC S7-1200 Basic Controller can be perfectly adapted to the automation task at hand thanks to its comprehensive expansion options. The modular board concept permits an easy expansion of the controller without changing the physical size. Device replacement is simple, without rewiring through terminal strips.

Safety Integrated

• Fail-safe automation is as easy to program as standard automation, and PROFIsafe devices are connected via PROFINET.

Technology Integrated

• Simple Motion Control applications, fast counting and measuring tasks, as well as closed-loop control systems (PID) are integrated and can be implemented without additional expansion boards.

Security Integrated

• Secured communication, know-how protection, copy protection and access protection prevent manipulation, opening and duplication of blocks by unauthorized persons, and thus protect your algorithm or process.

With the integrated technology functions such as High Speed Counter, pulse width modulation, pulse sequence outputs, speed control and positioning, SIMATIC S7-1200
Controllers are suitable for temperature controls, pump and fan controls, as well as conveyor technology including packaging machines.

Communication

The SIMATIC S7-1200 is equipped with a variety of communication mechanisms:

• Integrated PROFINET IO Controller interface
• Communications module with PROFIBUS DP master interface
• Communications module with PROFIBUS DP slave interface
• GPRS module for connection to GSM/G mobile networks
• LTE module for communication in mobile networks of the 4th generation (long term evolution)
• Communications processor for connection to TeleControl Server Basic control center software control center software via Ethernet, and for safe communication via IP-based networks
• Communications 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 communications modules or Communication Boards.

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

Communications 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).
