Abstract
According to current technological situation that most of the existing Modbus networks are based on cable and the disadvantages of cable in bus architecture such as troubles during installation, much inconvenience in maintenance debugging and the potential safety hazard following high non-isolated, a design proposal based on Modbus digital transmission module is presented to realize the communication function without cable. During the design proposal, a wireless RF A7108 chip offered by SHENGKE electronic company is selected as the transmission carrier, which is followed by the transmit-receive pattern of Modbus protocol. And the transmission reliability of wireless data is guaranteed by the CRC check of every frame in the process of data transmission. This design can improve the problem of cable dependence in the traditional bus system and has a certain practical value within 500 meters radius in the industry with cable arrangement difficulty.
