PLC SIEMENS SIMATIC S7 1200
The S7-1200 controller can be used in areas where the use of controllers was previously considered economically unprofitable (electronic devices were used to automate production).
SIMATIC S7-1200 focused on building automation systems for:
- metalworking machines;
- packaging and printing machines;
- mixing installations;
- elevators and escalators;
- pumping stations;
- warehousing, etc..
Simatic S7-1200 is a family of programmable logic controllers of modular design for universal use. In the line of controllers of this family, compared to the S7-300, S7-400 and S7-1500 families, it is positioned as a Basic Controller in terms of its performance.
What does SIMATIC S7-1200 consist of? The S7-1200 programmable controller includes the following modules:
- Central processing unit modules (CPU);
- Communication modules (CM);
- Communication processors (CP);
- Signal modules (SM);
- Boards (SB) for input/output of discrete and analog signals;
- Technology modules; Power supply module (PM 1207).
Configuring and programming the SIMATIC S-1200 controller
The Simatic STEP 7 Basic v13 software with embedded Simatic WinCC Basic software for programming HMI tools is used to configure and program the controller series.
The S7-1200 series is expanded with the simplest unmanaged 4-channel Industrial Ethernet switch and simulators.
Types of modules
In the table, we will consider the technical characteristics of the main types of modules of the SIMATIC S7-1200 controller.
Module name | Description |
Central processing unit (CPU) modules | 5 CPU models — CPU 1211C, CPU 1212C, CPU 1214C, CPU 1215C and CPU 1217C Built-in Ethernet interface, ability to connect up to three communication modules, one I/O board, configuration of 16 different connections for data exchange. To organize data exchange, transport protocols TCP/IP, ISO on TCP and S7 communication functions are used. The processor memory is expanded using memory cards with a capacity of 4MB, 12MB, 24MB, 256MB, 2GB |
Signal modules (SM), expansion modules | Connects only to CPU 1212C and CPU 1214C. Signal modules include 8- and 16-channel discrete input and output modules, 16- and 32-channel discrete input/output modules, 4-channel input modules and 2-channel output modules for analog signals, as well as an analog I/O module with 4 inputs and 2 outputs |
Discrete signal input/output modules | SM1221, SM 1222, SM 1223 |
Analog signal input/output modules | SM1231, SM 1232, SM 1234 |
Signal boards (SB) | SУ 1221, SB1222, SB1223, SB1232 |
Power supply (PS) | Input voltage ~115/230 V, output voltage =24 V and rated load current 2.5 A. |
Communication processors (CP) | Communication with devices with other interfaces is possible using additional communication modules with RS 232 or RS485 interfaces. Data exchange via Industrial Ethernet/PROFINET networks as well as PtP (Point-to-Point) connections is possible. |
Input Signal Simulators (SIM) | For CPU 1211C and CPU1212C, 8 built-in switches For CPU 1214C, 14 built-in switches. |
