摘要
介绍如何使用COM的MTA线程实现OPC服务器的异步数据传输 :首先说明OPC服务器的异步数据传输机制和使用多线程实现异步传输的优点 ;然后介绍COM的多线程技术 ;
This paper introduces how to use MTA technology to implement the asynchronous data transfer within OPC Data Access server and client.At first,the mechanism of OPC asynchronous data transfer and the advantages of using MTA to implement it are explained.Then more details of the COM multithread technologies are described.A case of using MTA to implement asynchronous data transfer in OPC Data Access server is given out in the end of the paper.
