Solution

To achieve the above goals, the company has chosen a comprehensive solution that combines Siemens S7-1500 automation system with Sinamics DCM DC speed control system.

System configuration


  • S7-1500 PLC

    As the brain of the entire production line, it is responsible for processing various signals from the site, executing control logic, and issuing control instructions.

  • Sinamics DCM DC speed control system

    used for precise control of motor speed and torque, ensuring stable operation of the production line.


  • HMI operation interface

    Provides intuitive operation and monitoring interface for operators, facilitating real-time monitoring of the production process and adjustment of parameters.

  • Network communication equipment

    Connect PLCs, speed control systems, and other intelligent devices through industrial Ethernet to achieve data exchange and centralized control.

Implementation steps

  • On site investigation comprehensively understand the process flow, equipment status, and control requirements of the existing production line.
  • Scheme design Design an automation transformation plan based on research results, including hardware selection, software programming, and system integration.
  • Equipment installation
    During the shutdown period, modify the existing electrical control system and install S7-1500 PLC and Sinamics DCM speed control system.
  • Program development Develop PLC control programs and HMI operation interfaces according to production process requirements.
  • System debugging After the equipment installation is completed, perform system debugging to ensure the correctness of control logic and the stability of the system.
  • Training and delivery
    Train operators on system operation and maintenance, and deliver the renovated production line for use.
