▪ Automation networks in the process industries
must fulfil many challenging requirements.
▪ Easy Installation
▪ Common Platform
▪ Continuous Operation
▪ Reliability
▪ High Signal Density
▪ Operation in Hazardous Areas

Only Intrinsically Safe technologies can operate in these areas.
Ethernet is not Intrinsically Safe!
Industry requires more data to improve processes.
A solution is required to enable this digital transformation

What is APL?
▪ A two-wire Ethernet for process automation and
hazardous locations, based on IEEE and IEC
standards.
▪ APL is a standard for the Physical Layer.
▪ The goal of APL is to bring Ethernet down to field
level instruments in hazardous areas.
▪ APL will limit current and voltage in the
physical Layer to have an intrinsically safe
solution.
▪ The physical connection will be a
rugged two-wire connection with power
over this cable.
▪ APL will exceed the 100 m limit of
100BASE-TX Ethernet networks to be
suitable for large installations.

The agreement to develop the Ethernet-APL technology under “The APL Project” was
established in 2018 and is backed by the leading industry standard development organizations
(SDOs)

APL and Profinet
▪ The limitation of Ethernet infrastructure has
now been removed.
▪ It can now be installed in hazardous areas and
over a wider area.
▪ Only the Physical Layer has changed. All other
layers of the ISO / ISO model remain unchanged.
Profinet can now reach field devices

Summary
▪ Ethernet-APL is a technology, that enables Ethernet
communication over 2 wires instead of 4 or 8 with
intrinsic safety into the hazardous environment.
▪ For end users, Ethernet-APL provides a secure, high-
speed powered ethernet networking solution
throughout the plant — including intrinsically safe
areas.
▪ For future projects, it allows for simplified project
infrastructure planning, speedier commissioning, and
provides ultimate flexibility with support for all
process automation communication protocols.
▪ Suppliers can take advantage of high-speed,
intrinsically safe, powered ethernet in their 21st
century instrument, infrastructure, and application
software designs.
