Control Based on PLC Networking to Air Conditioner

This text primarily introduces the PLC net application,establishes a bureau net to control the air conditioner of each workshop,guaranteeing the degree of humidity,of each workshop.In the whole system,the handle,delivering of information is the key,the application of the communication and the application of outer makes a detailed introduction in this text.The paper introduces the hardwares of PLC net in the air condition in the system,which are all Mitsubishi series products,this also reflects PLC intelligence.Along with the science technique continuous development,the PLC also continuously get perfect with strong,at the same time its function also consumedly exceeds the logic scope control,such as net correspondence function and the diagnosis function etc.,and with the PC machine affiliation the net is more perfected the network reliability.
