3. Design of Siemens S7-1200
The S7-1200 system consists of the following components:
+ CPU controller combined with three different types such as DC/DC/DC, AC/DC/RL, DC/DC/RL
+ Signal board is used to extend signal I/O or traditional communication with low cost and space saving because it is installed directly on CPU.
+ Different analog and digital signal I/O modules.
+ Various communication modules.
+ Ethernet switch with 4 ports to realize the connection of many different network models.
+ Terminal unit for the SIWAREX weighing system.
+ The PS 1207 power supply is stable with input voltage of 115/230 V AC, output voltage is rated 24 V DC.
4. Mechanical Features
+ Easy to install modules on a standard DIN rail (35mm rail) or in control panels.
+ Safe, sturdy plastic case.
+ Connections and controls are easily accessible, protected by front covers.
+ Terminals and modules can be easily installed and disassembled.
5. Communications
SIMATIC S7-1200 is equipped with different communication mechanisms:
- Built-in Profinet . communication interface
- Communication module PROFIBUS DP master
- PROFIBUS DP slave communication module
- GPRS module for connection to GSM / G mobile phone network
- LTE module for communication in mobile phone networks of the LTE (Long Term Evolution) generation.
- Communication processor for connection to TeleControl control center software via Ethernet and for secure communication over IP networks.
- Communication processor for connection to control centers for remote applications.
- RF120C for connection to SIMATIC Ident systems.
- Module SM1278 for connecting IO-Link sensors and actuators.
- Point-to-point communication module.
6. Profinet Communication
Profinet Communications allows connection to:
- Programming device
- HMI devices
- Other SIMATIC controllers
- “PROFINET IO” Automation Components
+ Connect the programming device to the personal computer via CAT5 cable
+ Connecting to an HMI Display
+ Connect Multiple Siemens S7-1200 Controllers
+ Point to point Interaction
- The communication modules that enable point-to-point connections are the RS322 and Rs485 physical communication interfaces. Data transfer is done in the “Freeport” mode of the CPU (a user-specific bit-oriented communication protocol such as ASCII, USS, or Modbus).
- The S7_1200 can communicate with any terminal with a point-to-point connection e.g. drives, printers, barcode readers, modems…
