Abstract
With the study of the format and the operating requirements of the ModBus communication protocol,plus the related module CP134 of Siemens PLC—S7-300,the paper achieves the objective of controlling the transducer by the communication mode of ModBus communication protocol,and gives the design approach and related process.According to the opening,simpleness,high efficiency and understandability of the ModBus communication protocol,the design of the system becomes more convenient,and the anticipative effect of control has been achieved more easily.
