微控制器与组态王以太网通信系统的实现

Implement of Ethernet Communication System between MCU and KingView

为了通过以太网实现组态王软件监控用户微控制器系统的数据信息,设计了一种基于欧姆龙FINS/UDP协议的微控制器与组态王通讯模块。该模块运用CORTEX-M3为内核的STM32F103T8单片机为核心器件,通过RS-485接口电路采集外部用户微控制器系统的数据信息,然后控制以太网控制器ENC28J60接收和响应组态王的FINS指令帧,从而间接实现微控制器系统与组态王的以太网通讯。

In order to use KingView to monitor the data of user＇ s MCU system through the Ethemet, the communication module between MCU and KingView based on the OMRON F1NS/UDP protocol is designed. STM32F103T8 is used as the core device in the module. Data information of the MCU system is collected by a RS485 interface circuit. ENC28J60 which is used as the Ethernet controller is controlled to receive and respond to KingView FINS frame. The Ethemet communication between MCU system and KingView is impelemted indirectly.
