Ethernet-APL GoalsAdvanced Physical Layer will bring the benefits of industrial Ethernet to process automation and instrumentation, PLUS . . .
o A converged long-distance communication network for process automation and field instrumentation.
o Ability to locate Ethernet-based field devices in hazardous areas by virtue of being intrinsically safe.
o Two-wire using industry standard fieldbus cable with loop-powered devices.
o Increased bandwidth provided by 10 Megabit, full-duplex Ethernet communication enables productivity gains over the lifecycle of field devices.
