| Abstract: | The RS485 serial technique is applied in communication between the seven air compressors and DCS and PLC systems in Coking Plant of Xuan Steel. It realizes the serial communication interface conver- sion, communication program development and application. It is proved the successful application of this project offers a successful example for Xuan Steel in its large - scale equipment development and the commu- nication between various types of PLC system and intelligent control system. |
