| 摘 要： | Modbus协议在1987年由施奈德公司制定,由于其简单而精致的结构得到大家的支持,目前,在电力行业Modbus协议也得到了广泛的应用,但是由于Modbus协议自身的特点与电力系统的使用习惯还有不相符的地方,在Modbus协议实现中还有一些问题,现从参数地址的编制、功能码的选择以及应用功能等方面讨论Modbus协议实现中的一些问题,并从特殊应用功能和常用应用功能对电力系统应用功能进行分析和举例。

| Abstract: | Modbus protocol formulated in 1987 by Schneider Co.,Ltd, obtained everybody as a result of its simple and the fine structure the support.At present, Modbus protocol is also obtained the widespread application in the power system but because the Modbus protocol own characteristic and the electrical power system use custom also had the place which did not tally, so had some questions in the Modbus protocol realization, this paper from parameter address establishment, functional code choice as well as application function, discusses in the Modbus protocol realization, analyses the electrical power system application function and gives an example from especial application function and common application function. |

| Keywords: | Modbus communication protocol parameter address establishment functional code application function |
