摘要
通过对FX2N和CPM1A系列PLC的上位机通信协议的分析,提出了协议转换的思路,设计了以P89C669FA为上位机的系统,借助协议转换实现两PLC之间的通信。该系统可在实时性要求不高的场合,低成本地实现不同品牌的PLC通信。
Based on the analysis of host link communication protocols,the idea for the protocol conversion was given between FX2N and CPM1A series PLC.By using P89C669FA MCU as a host computer,a communication system with protocol conversion is designed.This system can be applied at the field with low cost and low real-time demand.
