摘　　要：文章介绍了一种基于嵌入式通讯模块开发检测仪表的PROFIBUS-DP接口的方法,其中包括PROFIBUS总线、硬件设计、软件设计和参数配置。该设计方案具有完全遵循PROFIBUS-DP协议、兼容性强、运行可靠、开发周期短等优点,特别适用于已有仪表现场总线接口的开发。A development method of PROFIBUS - DP interface for measuring instrument based on embedded communication module is introduced, including PROFIBUS bas, design of hardware and software, and parameter configuration. Advantage of the design scheme is high compatibility and reliability, short development time, and to conform to PROFIBUS - DP protocol absolutely. It is particularly used in derelopment of fieldbus interface for existing instruments.
