Abstract: | This paper mainly describes the application of RS-485 bus in distributed control system(DCS). We also give a brief introduction of communication mode and protocol of Modbus RTU,the software and hardware structure of DCS processing station with RS-485 bus. The importance and urgency of openness design in DCS are also emphasized in this paper. |
