AN214
The PICmicro® MCU as an IEEE 1451.2 Compatible Smart Transducer Interface Module (STIM)
Authors: Richard L. Fischer Microchip Technology Inc. Jeff Burch Agilent Technologies The IEEE 1451.2 standard provides the means to connect sensors and actuators to a digital system, typically a network, via a Network Capable Application Processor (NCAP). Figure 2 depicts a general distributed measurement and control application and Figure 3 depicts the functional boundaries relating to the transducer interface standard, namely IEEE 1451.2. In simplest terms, the IEEE-1451.2 standard does the following: • Defines a digital interface for connecting transducers to microprocessors. • Describes a TEDS, “electronic data sheet”, and its data formats.
