| Abstract: | An application of SIEMENS S7-300 PLC and CD901 smart thermostat to the temperature control system of plastic extruder is introduced in detail. The controlling structure and the hardware selection of the temperature control system are described. By using communication processor CP340, the realization of RS-485 serial communication between SIEMENS S7-300 PLC and CD901 is proposed. |
