基于RS-485总线多CPU控制系统简化网络模型及其通讯协议

Simplified Network Model and Communication Protocol of the Multi-CPUs Control System Based on RS-485 Bus

基于RS-485总线的多CPU控制系统中各个CPU控制之间要协调工作,则网络模型和网络通讯协议是非常重要的。针对该种控制系统的特点,提出了适用于该系统的RS-485网络简化模型和通讯协议。

Network model and communication protocol is important for each controller of multi-CPUs control system based on RS-485 Bus to work in harmony.Being aimed at this control system＇s characteristic,network model and communication protocol being applied to this control system are suggested in this paper.
