thernet is the most commonly used computer networking
technology for local area networks (LANs) and is
standardized in IEEE 802.3. As Ethernet continues to find
its way into other applications, it is rapidly becoming the
network of choice for higher-level industrial control applications.
Industrial Ethernet is the result of applying traditional Ethernet
standards for data communication to industrial applications.
In addition, environmental noise can have a negative affect on
network performance. Electrical noise can come from nearby AC or
DC circuits, motor drives, welders, and other electrical equipment.
This results in increased RFI and EMI interference, which can
decrease system performance. Industrial network connectivity
needs to withstand all of these conditions and still reliably
perform. More and more applications require real-time data,
which increasingly makes Ethernet the optimal solution for today’s
industrial environments.
In order for Ethernet to be used in the industrial environment,
the cables and connectors must be adapted to withstand
environmental conditions that are not present in commercial
installations. These conditions include:
•

Keeping in mind the environmental conditions, one has to consider
which cable, communication protocol, and connector(s) will work
best for the installation. This guide will provide a brief overview of
some of the most common options available today.

Equally important as the connector you choose for your industrial
Ethernet application is the cable you choose. Off the shelf
commercial Ethernet cable does not withstand the demands of
an industrial environment. Rugged Industrial Ethernet cables,
such as those using TPE cable jackets, are designed to hold up
to the harsh environments common to industrial automation.

Four Pair Color Code
Industrial Ethernet cable commonly uses twisted pairs, which is
wiring where two conductors that are part of the same circuit are
twisted together. This process is intended to help cancel out EMI
and interference from other sources. In addition, an extruded cable
jacket on industrial Ethernet cables helps protect and hold the
twisted pairs together.

Ethernet Categories
Ethernet cables are referred to as category cables, because they
are classified into specific categories of performance. The table
below lists several common category cables and their associated
frequency, speed, and number of pairs. Note, CAT 5e is available as
either a 2-pair or 4-pair cable, but all 4-pairs are needed to achieve
the 1000 Mbps speed; only 2-pairs are needed to achieve 100 Mbps.
A commercial Ethernet cable does not typically carry any ratings
or approvals for industrial environments, and at most may include
a rating for plenum or riser air spaces, which generally does not
apply to industrial settings.
Industrial Ethernet cable does have a similar color code to
commercial Ethernet (ANSI/TIA 568-C.2). The tables below illustrate
the typical color codes used for industrial Ethernet applications.

An important consideration when choosing an Industrial Ethernet
cable is the overall desired performance of the system. If the
goal is to achieve 10 Gbps, then all devices and connecting
hardware (switch, PLC, I/O blocks, camera, etc) need to be rated
to the same speed. Your system will operate as fast as the slowest
device. Utilizing CAT 6A cabling will not force a CAT 5e switch to
operate differently.
a patch cable converting commercial Ethernet to the factory floor.
These connectors are capable of handling both 2 and 4-pair wiring
and come in both IP20 and IP67 styles.
IP20 RJ45 Connector:
Shielding
Shielded cordsets are an essential component of any connectivity
solution to combat cross talk, which is the unwanted transfer of
signals between communication channels and EMI/RFI. EMI/RFI
stands for “Electro-Magnetic Interference” and “Radio Frequency
Interference”, which is high frequency / low energy noise emitted
by factory devices such as motors, welders, power cables and
processing equipment. The noise emitted disrupts packet
transmission by overwhelming the normal signal information
within the electrical circuit. A double shielding approach, with
both foil and braided shield, is most effective in isolating the
data communication from the external environment. This design
takes advantage of the greater coverage of foil and the superior
conductivity of the copper braid. Additionally, proper bonded
grounding of all components is crucial to attaining effective
shielding. When in doubt on whether or not to use shielded cable,
err on the side of caution and choose shielded cables to prevent
costly system downtime and errors.

When transitioning to the unprotected industrial environment,
M12 Ethernet connectors are the superior choice for Industrial
applications. Their rugged overmold design provides ingress
protection against dirt and water as well as resistance to machine
vibration and accidental impact. These factors make them a better
choice for maintaining signal integrity and performance.
Note: Turck has bulk cable available for use with all major
protocols. For a listing of these, please visit the reference table
included at the end of this guide.
The M12 is available with three different pin configurations for
Industrial Ethernet use. There is a 4-pin D-code, an 8-pin A-code,
and an 8-pin X-code. The D-code M12 is intended for use with
2-pair (4-wire) Industrial Ethernet cables only. The 8-pin A-code
can be used with either 2-pair or 4-pair (8-wire) Industrial Ethernet
cable. The X-code is intended for use with only 4-pair shielded
Industrial Ethernet cable. This connector is further detailed in a
later section.
Understanding Your Options for Industrial
Ethernet Connectors and Cabling
It is important to consider the conditions that the connector
will be exposed to including how and where it will be mounted,
what shielding is required and the conditions of the overall
operating environment.
M12 connectors carry IP67 and IP69K ratings for industrial
applications, and are available with stainless steel components
suitable for environments requiring corrosion resistance. Similar to
RJ45 connectors, M12 connectors can be used with most all of the
existing Ethernet category cable types (i.e. CAT 5 up to CAT 7).
Connector Options
The RJ45 (8P8C) connector is the most widely
established connector technology for Ethernet
networks. These connectors are available for most
Ethernet categories (i.e. CAT 5e, CAT 6, etc.), and
RJ45 Endview their ease of use and quick connect/disconnect
feature makes them a natural choice for office
environments. RJ45 connectors are recommended only for limited
use in industrial environments, and in protected/enclosed areas, as

Newer applications for video, camera, and high-speed data
acquisition demand a network cable that can handle more than
10/100 Mbps data transfer. Gigabit Ethernet, which may refer to
1 Gbps or 10 Gbps, can provide the speed and capacity needed.
For 1 Gb applications, category 5e or higher cable is required.
For 10 Gbp applications, category 6A cable or higher is required.
Turck offers solutions for both. For applications that require 1 Gb
communication (or if you have more than four connection points
within the channel), it is recommended to use a CAT 5e, CAT 6, or
CAT 6A cable along with the higher rated X-code M12 connector.
For applications that operate at 10 Gb speed, it is recommended to
use our CAT 7 cable along with the X-code M12 connector.

The 4-pin M8, rated for IP67, is also available for use in Industrial
Ethernet applications. The smaller size of the M8 allows users to
bring Industrial Ethernet into applications with very limited space.
It is available with the shield tied to the coupling nut, as required
by the EtherCAT network protocol. The 4-pin configuration is
suitable for 2-pair Industrial Ethernet cables.

The X-code M12 features advanced shielding design. The metal
contact holder isolates each of the pairs from the others. When
paired with Turck’s CAT 7 cable (type 862), it can communicate at
10 GBASE-T. Turck’s CAT 7 cable is S/STP, where each pair has a foil
shield, and an overall braided shield. This overall shield is carried
through to the connector coupling nut, providing much needed
protection from external noise. In addition, the X-code M12 is
IP67 rated, and reliably operates in temperatures ranging from -20
degrees Celsius to 70 degrees Celsius.

times, these cameras are located in protected areas and do not
necessarily require a rugged M12. In this case, an RJ45 cordset with
CAT 6 cable is an ideal solution. Turck’s RJ45S RJ45S 861-*M works
well for cameras or in other protected areas. It utilizes 4UTPX26

codes, network protocol (i.e. EtherNet/IP, Modbus, etc), or the
system layout and personal experience. The ODVA recommends
terminating only one end to ground; at the switch or panel, not
at the active device. Conversely, PI recommends terminating both
ends to ground; at the device and back at the panel. Regardless of
the method chosen for the application, it is important to not leave
the shield floating or unterminated at either end. When a shield is
unterminated, it can act as an antenna and induce noise onto the
cable, potentially causing significant communication problems
for the system. While the task of determining which method of
terminating shield to ground may seem daunting, the use of a
shielded cable could lead to significant time and cost savings in
the future. For instance, if equipment is moved around, a new
machine is added, or additional cables are added to a tray where
Ethernet exists, shielded cables are much less likely to experience
communication problems due to unforeseen changes.
Power over Ethernet
Power over Ethernet (PoE) refers to the ability to transfer both
data and power within an individual Ethernet cable. Standards
have been established by the IEEE, specifically 802.3af and 802.3at,
which detail the minimum category cable, how power should be
delivered, and limits in terms of watts. Many applications have been
established in the commercial world (VoIP, surveillance cameras,
access control devices, etc.), and are making headway into the
industrial environment as well. Turck stranded Industrial Ethernet
cables (types 440, 441, 840, 841) are suitable for use in PoE and
PoE+ applications.
System Length:
When constructing your Ethernet topology, there are a few
important terms and considerations to be aware of. The overall
network infrastructure that interconnects various parts of the
network - allowing information to exchange hands - known as the
Ethernet backbone. Another common term is channel, which is
the overall system length, including horizontal cabling and patch
cables. Horizontal cabling refers to the longest run, typically solid
conductor, max length 90 M (ex: from patch panel to outlet), or up
to 100 M if you are direct connecting with no patch cables. Patch
cables refer typically to short cables or stranded conductors, up to
30 M total (ex: from outlet to device).
A similar but very different concept is the desire for both power
and Ethernet. The intent is the same, to utilize one cable for both
data and power. However, instead of supplying low voltage/current
over the data pairs, the cable includes additional larger gauge
conductors specifically for power, and may supply power up to
several amps. Power & Ethernet does not have any established
standards or governing groups dictating how it should be designed
or used. There exist many variations with different numbers of data
pairs, different numbers of power conductors, and different styles
of connectors. While Power & Ethernet does solve consolidation
problems, it may not always be the most cost effective solution due
to the custom cables and specialized connectors needed.
Industry Standards limits channel length to 100 M (copper cable).
Turck solid conductor Industrial Ethernet cables have full CAT 5e
performance to 100 M. Turck stranded Industrial Ethernet cables
have full CAT 5e performance up to 85 M.
Installation Guidelines
End-to-end Link
The following section is intended to highlight some common “best
practice” tips, for use in an Industrial Ethernet installation. Utilizing
these tips at the beginning of an installation can minimize troubleshooting after the installation. However, please keep in mind that
every application is different. It is understandable that, in certain
situations, these guidelines cannot be followed, but the systems
can still function properly. The most important factors to consider
with your application are the environment, the potential for noise
and what electrical codes need to be followed (UL, NEC, NFPA, etc.).
100 M Channel

Grounding Shielded Cable

When using a shielded Industrial Ethernet cable, it is important to
terminate the shield to ground. This is what prevents noise from
having a negative effect on the cable’s performance. The method of
terminating shield to ground may be dependent on local electrical

5M
This means that, in some installations, a Turck stranded industrial
Ethernet cable could be substituted for a solid conductor cable,
which may minimize inventory requirements for some customers
and make it easier when specifying a bill of materials.
Service Loops
Unlike general sensor cables, it is not typically recommended to
utilize service loops for extra Ethernet cable. The individual pairs of
an Ethernet cable are twisted and line up uniquely, so as to prevent
crosstalk between pairs. Anything that distorts the twisting or
alignment of the pairs has the potential to allow opportunity for
crosstalk. This includes coiling loops of Ethernet cable, which may
distort the pairs and their alignment. Whenever possible, try to
specify Ethernet lengths close to the actual length needed.
Connectors: It is recommended to minimize the number of
connection points within an Ethernet network. Each mated
connection point represents a short distance where Ethernet
pairs are untwisted, and therefore are more susceptible to noise
interference. Typical practice for Industrial Ethernet installations
is to utilize cordsets with male connectors on both ends; this
minimizes opportunities for someone to extend a cordset. All
receptacles and bulkheads are recommended to be female.
Regardless of connector type (RJ45, M12, M8), this is a common
practice for Ethernet connectivity. ODVA spec recommends
no more than six mated connections within a channel (Sec.
8-9.2.3.8). Anything more and it is suggested it could compromise
communication.
Proper Bend Radius
Static bend radius for Industrial Ethernet cables (stranded or solid,
shielded or unshielded) is 4x the cable OD (Outside Diameter). Solid
conductor cables are not recommended for flexing applications.
Instead, use a stranded conductor cable. Turck’s stranded Industrial
Ethernet cables (both shielded and unshielded) are rated for 1
million flex cycles at 10x cable OD, and for 10 million flex cycles at
20x cable OD.
Transition Out of the Cabinet
Turck offers a variety of connector options, to make transitioning
out of the panel into the industrial environment easier. Typically,
this means transitioning from an RJ45 to an M12, the preferred
connector for use in an industrial environment. Using one of
these receptacles or feed-thru style connectors can make the
transition simple.
Providing sufficient bend radius will allow the cable to absorb the
energy of bending over a greater portion of its length, increasing
its effective working life. Small increases in the radius of the bend
can produce substantial increases in cable life.
Tying Cables with Cable Ties
FKFDD or FKFD
FKSDED or FKSDE

When tying cable with self locking cable ties, always leave the ties
loose enough for the cables to move freely under the tie. Over
tightening will create stress points that can cause the conductors
to fail prematurely. Never tighten the cable tie to the point where
the cable jacket becomes deformed or pinched (Figure 1).

Eliminating Stress Points in Cable Dress
or M12s for Industrial Ethernet. Maintaining the twisted pairs
and correctly terminating the shield on a field wireable can also
add significant time to the initial setup of a network. The use of
molded connectors, which are 100% tested at the factory (even
certified tested for Category performance, upon request), can save
significant setup and trouble-shooting time when commissioning
a network.
Installing cables to allow for adequate stress loops and freedom
of motion will increase the life of the cables. Turck cordsets
incorporate molded strain reliefs that will assist in preventing stress
(Figure 2).
Communication Protocol
The term “Ethernet” refers to the lower-level communication
structure. Various versions, or implementations, of Ethernet are
available, such as EtherNet/IP, PROFINET, and Modbus-TCP. It is
important to note that while all of these different specifications
use nearly the same physical communication method and can
operate on the same cable simultaneously, they cannot necessarily
communicate with each other. For example, Modbus-TCP
devices cannot communicate with EtherNet/IP devices because
the messages and communication protocol have been defined
differently for these systems, even though the physical media
structure is the same.

EtherNet/IP™ is a communication protocol supported by the ODVA
for use in industrial automation and process control environments.
It takes the Common Industrial Protocol (CIP) and implements it
onto the foundation of Ethernet. CIP envelops a wide-ranging suite
of messages and services for a variety of applications, including
safety, control, configuration and information. EtherNet/IP provides
users with tools to deploy standard Ethernet technology for
industrial applications.

Field Wireables
For some installations, it may be very nearly impossible to not
use field terminations, but whenever possible, if a pre-molded
connector can be used, it should be. The vast majority of
commissioning errors occur due to field wiring. It takes a lot of
practice (and errors) to excel at field terminating either RJ45s
EtherNet/IP is very flexible with star, tree or line topology, but using
managed switches is preferred in industrial applications. The use of
managed switches allows the network to be configured to perform
as close as possible to a real-time behavior that is often required in

industrial applications.
PROFINET can be used with line, ring, star and tree network
topology and uses Ethernet technology that has been adapted for
use in industrial environments.
The physical layer is defined in Ch 8 of the “EtherNet/IP Adaptation
of CIP”, which includes specifications for the cables and connectors.
This spec includes the D-code M12, X-code M12, and industrialized
RJ45 (8P8C) as suitable connectors for EtherNet/IP. The spec defines
component performance up to 100 Mbps, which means only two
pairs are required (one pair for Tx, one for Rx). A four pair cable can
be used, as long as all conductors are correctly terminated. CAT 5e
cable is recommended; teal is a common jacket color, though the
spec does not have a firm requirement. The conductor colors follow
the T568 standard.
The media for PROFINET is detailed in “PROFINET Cabling and
Interconnection Technology: Guideline for PROFINET”. The same
connectors used for EtherNet/IP are also used for PROFINET:
the D-code M12, X-code M12, and industrial RJ45. The cable
requirements are different, though. A minimum of CAT 5 cable is
recommended; it can be solid or stranded. A two pair cable is 22
AWG, and a four pair cable can be 22-24 AWG. PROFINET does not
allow for unshielded cables.
Per the ODVA, either shielded or unshielded cable can be used.
When using shielded cable, the ODVA recommends tying shield
to earth ground at one end only (typically, at the switch or panel,
not the active device) to prevent ground loops. For in depth details
on grounding methods, refer to the “ODVA Media Planning and
Installation Manual”.
PROFINET utilizes equipotential bonding, to minimize the impact
of electromagnetic interference. This requires connecting the cable
shield to ground at both ends of a cordset (typically via shield
tied to the coupling nut). Detailed explanation of grounding a
PROFINET network can be found in the “PROFINET Installation
Guideline for Cabling and Assembly”.
PROFINET should never be more than 100 Mbps, so CAT 5 cable is
sufficient . The cabling can consist of 2-pair or quad and be type A,
B, or C.
Modbus TCP is the Modbus RTU protocol with a TCP interface
running on Ethernet. Modbus is managed by the Modbus-IDA User
Organization. TCP refers to Transmission Control Protocol, which
provides the transmission channel for Modbus TCP messaging.
Modbus TCP is used often in the industrial environment due to
its ease of deployment and maintenance, and because it was
developed specifically for industrial applications.
Type A: Stationary with no movement after installation
(Solid Cable).
Modbus TCP can be used with star, tree or line network topology
and can be implemented with Ethernet technology that has been
adapted for use in the industrial environment.
Note: Turck PROFINET cable 423 is designed for use in both
type B and type C applications, and is suitable for use in type A
applications. This can be an added benefit to customers looking to
minimize their inventory and simplify Bill of Materials.
Type B: Flexible, occasional movement or vibration.
Type C: Special applications including highly flexible, permanent
movement, vibration or torsion.
Unlike EtherNet/IP, there is no specification for the physical layer
media to use with Modbus TCP. Regardless, the devices designed
for Modbus TCP utilize nearly identical cable and connectors as for
EtherNet/IP: D-code M12, 8-pin M12 (A-code), and industrial RJ45s.
Performance is intended for up to 100 Mbps with a two pair cable,
so a minimum of CAT 5 is required; cable typically has a teal jacket
color, and conductor colors follow the T568 standard. The cable can
be shielded or unshielded. It is also recommended to tie shield to
earth ground at one end only, to prevent ground loops.
EtherCAT™ is a communication protocol managed by the EtherCAT
Technology Group (ETG). The technology uses a clear master/slave
communication model.
EtherCAT is often referred to its ability to process data “on the fly.”
Unlike other Industrial Ethernet protocols, the master sends out
a single message with data for all nodes. The message transmits
to a following node while data is processed by the previous node.
In this way, it maximizes use of bandwidth available, providing
increased speed.
PROFINET™ is a communication protocol managed by PROFIBUS
and PROFINET International (PI) based on the open Ethernet
standard. PROFINET features a modular design structure allowing
users to select the cascading functions, including standard TCP/IP
for applications not requiring real time performance, Real Time (RT)
for applications requiring the transfer of critical information, and
Isochronous Real Time (IRT) for applications using functionality like
motion control.
Also, unlike other Industrial Ethernet protocols, EtherCAT does not
require the use of external switches or routers. EtherCAT devices
use an embedded switch.

A Ring topology is a network that is connected in a circular fashion
where data primarily travels in a single direction (Figure 6). In this
topology, every node is critical as data travels through each device
in the ring until it reaches the destination. It is not as commonly
used as the other topologies as it often requires more cabling.
EtherCAT can be used with line, tree and star network topology.
An overview of EtherCAT media is detailed in “Infrastructure for
EtherCAT/Ethernet”. A minimum of CAT 5 cable is recommended.
Again, communication is available up to 100 Mbps, so only two
pairs (four wires) are needed. Cable can be solid or stranded. Similar
to PROFINET, EtherCAT requires shielded cables only, and shield
should be terminated to ground at both ends. EtherCAT utilizes the
D-code M12, four pin M8, and industrial RJ45s.
Network Topology
NODE
NODE
Network topology is the physical arrangement of the components
used in the layout of a network including devices and cabling.
NODE
A Star topology consists of each network node being connected
to a central location (usually a switch) using a point-to-point
connection (Figure 4). The physical layout of the network does not
need to look like a star but rather each node must be connected to
one central point. A star topology is the most common topology
used because one faulty node does not cause an entire line to
experience downtime.
A Tree topology is a network that consists of a hierarchy of nodes.
The first level in a network tree consists of a single node, also
called a root (Figure 7). This node is then connected to either an
additional single node or multiple nodes in a lower level in a pointto-point manner. The lower levels then connect in a similar manner.
A tree topology is typically used by applications where frequent
node additions are expected, as it provides for easy expansion.

A Line topology is a network where each node is connected to a
main line or trunk. The information travels in both directions to all
nodes connected on the line until a match for the information is
found (Figure 5). A line topology is typically used by integrators or
by applications where low cost is a determining factor because it
costs less to install than the other topologies.
