介绍了WeinView触摸屏与计数器的通信系统,分析了MODBUS通信协议,对基于MODBUS协议的触摸屏与计数器的异步串行通行进行了研究。以触摸屏作为上位机,计数器作为下位机,通信系统采用MODBUS协议的RTU数据传输格式编程,实现了触摸屏与单台或多台计数器的通信,构成了一个集散控制系统。

We introduce the communication system between WeinView touch-screen and counter,analyse MODBUS protocol,study the asynchronous serial communication between touch-screen and counter based on MODBUS protocol.We use the touch-screen as PC and the counter as next crew and use MODBUS RTU protocol data transmission format in communication system.The communication between touch-screen and one or multiple counters is achieved and a distributed control system is formed.
