Design and Implementation of the Instrument in Process Supervisory Level Based on Modbus Protocol

Zhou Ze-kui

Abstract

According to Modbus industrial network,developed the instrument in process supervisory level.The instrument respectively achieved the data exchange between operator and PLC and between manager and operator by Modbus RTU protocol.Otherwise,it provided a standard current signal output to digital display instrument in the same level about a certain important parameter.In general,the instrument is universal and real-time to Modbus network,and it′s easy to operate,and has the friendly interface.
