摘要
针对当前各种总线共存、无法实现互连互通的状况,通过对EPA和PROFIBUS-DP基本特性的分析,提出了EPA与PROFIBUS-DP总线互连的协议转换网关模型,详细介绍了该协议转换网关的硬件结构和软件实现方法,构建了实验测试网络,实际测试表明所研发的EPA与PROFIBUS-DP协议转换网关运行稳定可靠。
To the state of the art of fieldbus ,which a variety of bus coexist and the interconnection among different bus is difficult, we presented a protocol conversion gateway model for the interconnection of EPA and PROFIBUS-DP on the basis of analyzing the basic characteristics of EPA and PROFIBUS-DP. And then, this paper discussed the protocol translation gateway＇s hardware structure and exactly described the method of implementing the gateway software. Finally, a test network was built and the test results show that the protocol conversion gateways between EPA and PROFIBUS-DP is stable and reliable.
