SIMATIC S7-1200
The modular controllers for innovative system solutions in the manufacturing industry
The SIMATIC S7-1200 controller is modular and compact, versatile, a secure investment, and is powerfully fit for a full range of applications. A scalable and flexible design, a communication interface that fulfills the highest standards of industrial communication and a full range of powerful integrated technology functions make this controller an integral part of a complete and comprehensive automation solution.

Scalable and Flexible Design
Up to eight Signal Modules can be connected to the largest CPUs. One Signal Board can be connected to all CPUs, allowing you to customize the CPUs by adding digital or analog I/O to the controller without affecting its physical size. The modular concept provided by the SIMATIC S7- 1200 allows you to design a controller system to exactly fit your application needs.
Memory
Up to 50 KB of integrated work memory is provided with a floating boundary between the user program and user data. Up to 2 MB of integrated load memory and 2 KB of integrated retentive memory are also provided.
Communication
Up to 3 Communication Modules can be added to any of the SIMATIC S7-1200 CPUs. The RS485 and RS232 Communication Modules provide the connection for performing Point-to-Point serial communication. This communication is configured and programmed using extended instructions or with the library functions, USS drive protocol and Modbus RTU Master and Slave protocols, which are included within the STEP 7 Basic engineering system.
Integrated PROFINET Interface
The integrated PROFINET interface is used for programming, as well as for HMI and PLC-to-PLC communication. Additionally, it supports communication with third-party devices using open Ethernet protocols. This interface features an RJ45 connector with auto-crossover functionality and provides for data transmission rates at 10/100 Mbit/s. It supports up to 16 Ethernet connections and the following protocols: TCP/IP native, ISO on TCP, and S7-Communication.
Integrated Technology Functions
High-speed inputs The new SIMATIC S7-1200 controller comes with up to 6 high-speed counters. Three inputs at 100 kHz and three inputs at 30 kHz are integrated for counting and measuring.
