Abstract The general situation and working principle of central air-conditioning control system are introduced as well as the application of PLC. Based on PLC and MCGS Configuration, the air-conditioning monitoring system is developed whose functions cover a wide range from display of working process of the system, control of equipment start-to-stop processes, display of trend curve to data and alarm display. This system has essfully been applied in engineering and it is well accepted. Key words Central air-conditioning System Monitoring System PLC MCGS
