Replacing analog 4-20 mA technology with a digital network was a major driver behind developing FOUNDATION fieldbus technology. However, what really differentiates FOUNDATION fieldbus from Profibus PA, HART and other process automation technologies, is incorporating a function-block structure and other supporting functions that make Foundation technology a complete infrastructure for process automation. A recent ARC white paper outlined this philosophy, describing FOUNDATION fieldbus as a true automation infrastructure that can help HPI and other process plants achieve operational excellence. Embedded control functionality in field devices ("field control"), one of the key enablers for ach
