Siemens S7 1200 PLC

Product Description

The S7-1200 controller provides the flexibility and power to control a wide variety of devicesin support of your automation needs. The compact design, flexible configuration, andpowerful instruction set combine to make the S7-1200 a perfect solution for controlling awide variety of applications.The CPU combines a microprocessor, an integrated power supply, input and output circuits,built-in PROFINET, high-speed motion control I/O, and on-board analog inputs in a compacthousing to create a powerful controller. After you download your program, the CPU contains the logic required to monitor and control the devices in your application. The CPU monitorsthe inputs and changes the outputs according to the logic of your user program, which caninclude Boolean logic, counting, timing, complex math operations, and communications withother intelligent devices.The CPU provides a PROFINET port for communication over a PROFINET network.Additional modules are available for communicating over PROFIBUS, GPRS, RS485, RS232, IEC, DNP3, and WDC networks. 

Several security features help protect access to both the CPU and the control program:

Every CPU provides password protection (Page 87) that allows you to configure accessto the CPU functions. 

You can use "know-how protection" (Page 89) to hide the code within a specific block. 

You can use copy protection (Page 90) to bind your program to a specific memory card orCPU.

New modules expand the power of the S7-1200 CPU and provide the flexibility to meet yourautomation needs: 

Industrial remote control communication modules: You can use these CPs ascommunication modules with the S7-1200 V4.1 CPU. 

Fail-safe CPUs and I/O: There are four fail-safe CPUs and three fail-safe signal modules(SM) in conjunction with the S7-1200 V4.1 or later release:

  CPU 1214FC DC/DC/DC  

CPU 1214FC DC/DC/RLY  

CPU 1215FC DC/DC/DC 

CPU 1215FC DC/DC/RLY 

SM 1226 F-DI 16 x 24 VDC

SM 1226 F-DQ 4 x 24 VDC 

SM 1226 F-DQ 2 x Relay You can use the S7-1200 standard signal modules (SM), communication modules (CM),and signal boards (SB) in the same system with fail-safe SMs to complete yourapplication control functions that do not require a functional safety rating.
