The SIMATIC S7-1200 CPU serves as the central processing unit for the S7-1200 series programmable logic controllers (PLCs). It’s responsible for executing the user program, handling communication with other devices, and managing I/O operations. Here are some details about the SIMATIC S7-1200 CPU:
- S7-1200 CPU 1211C: This is the basic CPU model in the S7-1200 series. It is compact and suitable for small automation tasks. It features digital inputs and outputs onboard and supports expansion with additional modules.
- S7-1200 CPU 1212C: This CPU offers extended functionality compared to the 1211C model. It supports more digital and analog inputs and outputs onboard, providing greater flexibility for a wider range of applications.
- S7-1200 CPU 1214C: The 1214C CPU is designed for medium-sized automation tasks. It offers increased performance and memory capacity compared to the previous models, enabling the handling of more complex control tasks.
- S7-1200 CPU 1215C: This CPU further extends the capabilities of the S7-1200 series with increased performance and memory capacity. It is suitable for larger automation projects with higher demands on processing power and data storage.
- S7-1200 CPU 1217C: The 1217C CPU is the most advanced model in the S7-1200 series. It offers the highest performance and memory capacity, making it suitable for demanding automation applications with complex control requirements.
- S7-1200 CPU 1214C DC/DC/DC: This variant of the 1214C CPU is designed specifically for use in applications where a DC power supply is required.
- S7-1200 CPU 1215C DC/DC/DC: Similar to the 1214C DC/DC/DC variant, this model of the 1215C CPU is optimized for use with a DC power supply.
These CPUs are the core components of the S7-1200 PLC system, providing the processing power and functionality required to control and monitor various industrial processes and machines. They can be programmed using Siemens’ STEP 7 Basic software, allowing users to create customized control logic to suit their specific automation needs.
