Application:
Siemens standard PLC main units find wide applications: They precisely control servo motors for packaging film positioning in packaging machines, enable multi - axis motion control in textile/woodworking machinery for high - precision processing. They integrate into smart production lines for data communication and material sorting, coordinate automobile production line operations, control machine tool actions, and automate sewage treatment processes by monitoring and regulating equipment based on sensor data.
