Current Activities to Bring an Advanced Physical Layer to Industrial Ethernet
► Emerging amendments to the IEEE 802.3 Ethernet standard
• A Task Force sponsored by the IEEE 802.3 Working Group, the IEEE 802.3cg Task Force, is
developing standards for a physical layer operating at 10 Mb/s over single-pair cable with
power delivery
► Cooperation to promote the development of an Advanced Physical Layer for
EtherNet/IP, HART-IP and PROFINET
• Three organizations - Fieldcomm Group, ODVA and PI - are jointly hosting activities to
promote development of an advanced physical layer for industrial Ethernet that is compliant
with future amendments to the IEEE 802.3 Ethernet standards and suitable for in hazardous
locations typically found in the process industry
• A group of suppliers to the process industry is supporting the cooperation with resources to
accelerate the development of technology for an advanced physical layer for use in products
for process automation and instrumentation.

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

Cooperation to promote the development of an Advanced Physical Layer for
► Organizations. Promotion of an advanced physical layer for industrial Ethernet and integration of amendments to IEEE
802.3 for single-pair Ethernet into their respective standards for industrial Ethernet with additional specifications for its
use in hazardous locations where intrinsically safe devices may be preferred and/or demanded.
► Suppliers. Joint research and development to accelerate development of technology and components needed to make
and sell Ethernet-connected products with an advanced physical layer that meets IEC standards for intrinsically safe
process field devices and related Ethernet infrastructure.
The initial period of cooperation is planned through 2020
following anticipated publication of the IEEE 802.3cg standard in 2019.
THE COOPERATION ACTIVITY FILLS IN THE GAPS IN THE IEEE ACTIVITY
BY FOCUSING ON THE USE CASES, TECHNOLOGY AND REQUIREMENTS TO REALIZE
AN ADVANCED PHYSICAL LAYER FOR PROCESS FIELD DEVICES.

Technology Overview of Advanced Physical Layer
Trunk
► Installation in hazardous areas Zone 1, Class 1, Division 1
► Cable length <=1000 meters
► Data transmission at 10 Mbps, full duplex
► Intrinsic safety for non-powered devices
► Increased safety for up to 50 powered devices @ 500
milliwatts
Spur
► Installation in hazardous areas Zone 0, Class 1, Division 1
► Cable length <=200 meters
► Data transmission at 10 Mbps, full duplex
► Intrinsic safety for non-powered devices and powered

Installation Considerations
► Trunk and Spur Compatible with 2-wire, shielded fieldbus
cable according to IEC 61158 type A.
► APL Ethernet Switch separately powered or trunk-cable
powered for increased safety
► Intrinsic Safety verification similar to FISCO
Supports proven trunk-and-spur topology used in fieldbus installations today

Compatible with proven industrial Ethernet standards used today and
future additions to Ethernet standards such as Time Sensitive Networking
Technology Overview of Advanced Physical Layer
Impact
► None to protocol stack
► Devices must integrate
Ethernet physical layer for
IEEE 802.3 standards
emerging from cg Task Force
and interface circuitry for the
Advanced Physical Layer
► Network architecture must
use of APL Ethernet switches

Organization Perspectives
“APL will be a significant advancement for our
industry by extending existing Ethernet technology
to address our traditional two-wire topology and
intrinsic safety,” stated Ted Masters, president of
FieldComm Group. “Like today, multiple protocols
will be used in all facilities, but with the added
capabilities of APL and Ethernet based
technologies. With integration through FDI and its
information model, our industry can now shift their
focus from the protocol to capture value of the
information provided by field devices.”

“EtherNet/IP has proven that it offers users
significant benefits in performance, ease-of-use,
and its substantial ecosystem of suppliers.
EtherNet/IP is future-ready to take advantage of
the many exciting developments coming to
industrial Ethernet including single-pair Ethernet
which will offer simplified and lower-cost
connection schemes for users a variety of
applications. Users in the process industry will be
one of the biggest beneficiaries of the future
advanced physical layer technology.”

“Industrie 4.0 driven innovations, in particular,
Ethernet-based communication systems are the main
driving force for increasing the profitability of
process industries, which production systems have to
work for years without interruption in rough
environments. Today, there is still a need for a
solution with which PROFINET devices can also be
provided for use in hazardous areas based on two-
wires and supplying power over the line. This is why
PI pushes the implementation of APL – the
corresponding physical layer for Ethernet
communication – being created in a joint project with
well-known industrial companies and organizations.”

Outlook for the Future The Advanced Physical Layer provides
familiar and proven installation techniques
for Zone 1, Division 2, and
Zone 0, Division 1, installations . . .
. . . and all of the other benefits of Industrial Ethernet
► Improved diagnostics
► Easy engineering
► Less specialized training
► Complementary to Namur Open Architecture and Industrie 4.0 initiatives
► Increased performance
► Easier device integration
To prepare for potential future enhancements to the Advanced Physical Layer, industry will
investigate the potential to support systems that could benefit from increased bandwidth.
