Ethernet-APL (Advanced Physical Layer)•••

Problem: Ethernet is very common in communications but does not meetthe requirements for the process automation field, specifically process
plants with hazardous areas.
Goal: to be able to use Ethernet in hazardous areas (explosion potential)
Ethernet-APL:
Ethernet with an Advanced Physical Layer (Ethernet-APL) will enable longcable lengths and explosion protection via intrinsic safety with
communication and power over two wires.

Ethernet-APL Specifications•

Derived from IEEE 802.3cg (SPE), Ethernet-APL references and standardizes
industrial automation extensions.

•Ethernet-APL defines port profiles for multiple power levels with and without
explosion hazardous area protection••

Markings on devices and instrumentation indicate power level and function as sourcing
or sinking.
This provides a simple framework for interoperability from engineering to operation andmaintenance.

Ethernet-APL Specifications•

Ethernet-APL uses Trunk and Spur topology••

The “Trunk” provides high power and signal levels for long cable lengths of up to1000m
The “Spur” carries lower power with optional intrinsic safety for lengths of up to200m

Ethernet-APL Conformance Test•

Ethernet-APL Conformance Test•••

Data Tests (17 test sections) analyze data and signal integrity under various
testing conditions
Power Tests (18 test sections) analyze electrical characteristics specific to theDUT (source vs load, spur vs trunk, etc.)

ODVA will support Ethernet-APL conformance testing with eventual planned
integration into CT19
