The Whisper on the Wire: HART, Device Descriptions and FDI
During commissioning at the Al Sahil Gas Complex, Rafael "Rafa" Ortega, the commissioning manager, has eight thousand instruments to loop-check and a schedule that does not allow it. Diego Ferrer, the EPC's lead instrument engineer, thinks most of the answer has been on the wires all along: a faint digital whisper riding on every 4-20 mA loop. Together they explain how HART works, why it has outlived every rival, how device descriptions and FDI let one tool configure thousands of different devices, and what HART must never be trusted to do in a safety loop.
