Abstract

PLC of the low layer of network in the paper communicates with field equipment by fieldbus or Modbus. And all PLC of the upper layer implements Ethernet hybrid network control system. The paper proposes a hybrid control network system based on PLC. The programmable controller TWDLCAE40DRF has the function of PID control on 13 parameters. So the programmable controller TWDLCAE40DRF can be used to control transducer to change the pressure value of water pipeline and maintain constant pressure of water pipelines. HMI is used to monitor the pressure of pipelines and adjust PID parameter in control.
