摘　　要：为简化传统设计中复杂的变送器与网络通讯的问题 ,IEEE14 5 1.2标准将变送器与微处理器以及微处理器与网络之间的接口标准化 ,使变送器模块达到即插即用的功能。介绍了IEEE14 5 1.2标准 。IEEE 1451.2 standards' objective is to simplify the complexities designers have traditionally faced in establishing communications between networks and transducers.The goal is to standardize the interfaces to efficiently connect transducers to micro-controllers and to connect micro-controllers to networks.In its simplest terms,1451.2 specifies a plug-and-play capability in a transducer module.The IEEE1451.2 standard is presented.The implementation of an IEEE1451.2 compatible interface and function on the DX digital smart pressure transmitter is outlined.
