摘要
针对工控网络的特点,提出进程的客户/服务器模型是异构工控以太网PLC间通信服务软件的最合适模型,介绍了一种基于该模型的用API函数调用方式实现异构PLC工控网络互联的方法。详细分析了互联软件编制过程中使用的关键技术,通过对源程序的设计理念和框架的分析,印证了用该技术实现异构PLC工控网络的无缝联接的科学实用性。
This papaer advanced that the client/server model of process is the bes t model for heterogeneous PLC communication service software on industrial Ether net in accordance with its special characteristics, and proposed an ideal of se amless connection between heterogeneous PLC networks in control systems by invok ing API function based on the model. The key technique used in communication ser ve software were analyzed in detail. Through the analysis of the program, the scienti fic practicability of the method is verified.
