摘要
智能开关柜操控装置具有RS485现场总线,适合于采用Modbus-RTU协议来实现与上位机的串行通信。本文根据Modbus协议的定义以及智能开关柜操控装置采集信息的种类和特点,完整地设计了智能开关柜操控装置与上位机通讯的Modbus-RTU通信协议,并采用VC＋＋程序设计语言实现了该通讯协议。
The digital control device of the intelligent switchgear with RS485 fieldbus is suitable for communication with the host computer by Modbus-RTU protocol.According to the definition of the Modbus-RTU protocol and the feature of data acquired by the intelligent switchgear control device,an integrated Modbus-RTU serial communication protocol between the intelligent switchgear control device and host computer is designed in the paper.Then the protocol is implemented in Visual C＋＋ program development environment.
