摘　　要：设计了一种Profibus-DP转换接口。以ATmega64、SPC3为核心,设计了转换接口硬件和软件流程,编写了GSD文件。该接口实现了将不具备Profibus通信能力的传统仪表和现场设备接入Profibus-DP。测试结果表明,该接口可与主站进行高速数据通信,有较好的可靠性和通用性。A Profibus-DP trausform interface was designed. Taking ATmega64 and SPC3 as core, hardware of interface, software flow and GSD file were designed. The interface implemented access of Profibus-DP for traditional instrument and field equipment which weren＇ t provided with Profibus communication ability. Test results show that the interface can run data communication with main station at high speed, with high reliability and versatility.
