The Emerson VE4019P0 is a DeltaV M-Series Series 2 Plus FOUNDATION Fieldbus H1 interface module used to connect DeltaV DCS systems to FOUNDATION Fieldbus smart field devices. It is designed as an upgraded Fieldbus interface generation that supports multiple segments and higher I/O density compared to earlier VE4017-series modules.
It functions as a Fieldbus communication gateway and Link Active Scheduler (LAS), managing communication timing, power coordination, and diagnostics across multiple Fieldbus segments.
