　　Abstract :IEEE 1451. 2 standards’objective is to simplify the complexities designers have traditionally faced in estab2 lishing 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.
