Research on Maglev Power Heat Pipe Refrigeration Control System Based on 1200 PLC Modbus Serial Communication Acquisition Technology

This paper introduces a maglev power heat pipe refrigeration control system based on 1200 PLC Modbus serial communication for multi-channel temperature detection. On the basis of the Modbus serial communication protocol, through the master-slave transfer between the Siemens S7-1200 PLC master console and the SS7-16 RTD thermistor input slave station, the temperature and humidity monitoring and control of the entire system can be achieved. The purpose of data display for the system. It found that the system has high operating efficiency.
