This white paper discusses considerations for implementing Ethernet networks in industrial environments. Key differences from office networks include exposure to environmental hazards, need for long cable runs, and importance of deterministic network performance for automation and control. Proper planning includes understanding standards for environmental conditions, equipment protection ratings, and selecting industrial-rated switches, shielded cabling and fiber optic cables where needed. Segmenting corporate and production networks and preventative maintenance are also recommended to maximize network reliability.
AUTOMATING DATA FOR IIOT ASSET MANAGEMENT & CONTROL - A HOW TO FRAMEWORKAnastasia Govan Kuusk
The paper describes an evidence based construct hierarchy for engineering asset management based organisations to effectively bridge the great divide of operational (OT) and information technologies (IT) for data driven, automated asset management decision making. The research followed an interpretive epistemology conducted as case studies of seven mining, utility and defence based organisations and over fifty Technology and Engineering practitioners to establish TOP constructs through Delphi study survey rounds and interviews. The research findings suggests that end to end technology governance from asset to office is a complex, holistic, information governance driven system. The research highlights that governing of technology, organisational process and people (TOP) constructs in such a complex holistic system of converged OT and IT technology environment is beneficial to Engineering Asset Management (EAM) based organisations for value chain automation by consistently governing data. Without a framework to manage the complex system constructs organisations are unable to achieve timely, reliable, sustainable automated decision making and cost effective use of existing technology staff, hardware, software, networks and governance processes. The research findings prioritised TOP information governance based constructs across applications, telecommunication networks, data, tag and people management aspects of organisational ISA95/MES technology stacks. The resulting framework is an easy to apply conceptual framework for practitioners
Practical Troubleshooting and Problem Solving of Ethernet NetworksLiving Online
While the basic structure of Ethernet has not changed much, the faster technologies such as Fast Ethernet and Gigabit Ethernet have increased the complexity and choices you have available in planning and designing these systems. As Ethernet has become more complex, a number of misconceptions have arisen as to how Ethernet functions and how the system should be optimally configured. This manual addresses these issues in a clear and practical manner, thus enabling you to apply the technology quickly and effectively in your next project. This manual commences with a brief outline of the Fundamentals of Ethernet and its operation.
The method of access is discussed in depth, and topics such as full duplex and auto negotiation are explained. The best methods of designing and installing the cabling systems are then explored with the discussion ranging from 10Base-T over twisted pair to Gigabit Ethernet cabling. Methods of optimising Ethernet to obtain best performance are then defined. Finally the all important topic of troubleshooting is examined with a summary of the typical problems you are likely to encounter from a two station network all the way up to a system comprising 30,000 PCs.

Stable Ethernet TCP/IP Real Time Communication In Industrial Embedded Applica...IJRES Journal
A stable Ethernet communication link in industrial embedded applications and networking are possible at all levels of industrial automation, especially in the controller level whereby the data exchanges in real-time communication is mandatory. Designing a Robust and Reliable Industrial Communications Infrastructure with Ethernet has traditionally been used to network enterprise workstations and to transfer non-real-time data. The success of Ethernet in the desktop world has been due to its simplicity, expandability, robustness, and affordable implementation. Based on Ethernet’s success as a data network, embedded soft real-time communication networks are being implemented with standard 100 Mbit/s Ethernet for economy, familiarity, and compatibility with enterprise networks. By using TCP/IP on top of Ethernet, embedded systems can become globally accessible from enterprise networks. This connectivity and interoperability is possible, and affordable using commodity off-the shelf (COTS) hardware and software, which has led to a recent surge in interest in embedded Ethernet.

Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Industrial-strength Ethernet comes of age
Ethernet is the most prevalent LAN application worldwide, offering the benefits of standardization, low-cost components,
and high-performance switching technology. It’s easy to configure and install.
Ethernet has steadily migrated from the office environment onto the factory floor for automation and industrial control,
in industries as wide ranging as food processing, mining and automotive and heavy-equipment manufacturing. As the
technology becomes increasingly efficient and affordable, even small manufacturers are now transitioning to Ethernet.
The shift from only legacy field-bus communication systems to new protocols on an Ethernet backbone not only improves
the ease of process control and automation, but also gives management visibility into real-time production information,
allowing them to streamline operations and improve productivity.
While there are many similarities between corporate and industrial Ethernet networks, there are also crucial differences.
The standard corporate Ethernet cannot simply be “teleported” into an industrial environment and succeed.
Whether you are considering Ethernet for your factory floor, are a system integrator whose customers are asking you to
install Ethernet, or you’ve already deployed Ethernet to automate production, this white paper will help you assess the
three most important areas: the network, electrical signals, and cabling infrastructure. Planning and prevention, as well
as selecting equipment that best suits your environment, will go a long way towards ensuring your network runs reliably,
and minimizing the impact of downtime.
What makes the industrial setting so different?
The biggest issues in industrial Ethernet stem from the hazards to which networks are exposed. Two major factors
contribute to these hazards: lack of climate control and the presence of other electrical equipment. While the
network in an office or data center is protected from nature’s elements by air conditioning and shade, most industrial
environments lack such climate control. Excessive heat and humidity, for example, can impact the transmission media.
Unshielded twisted pair cable, commonly used in office networks, can be damaged by prolonged exposure to sunlight.
The electromagnetic interference (EMI) generated by electrical equipment causes noise that impedes network traffic.
RJ-45 connectors, a mainstay of corporate networks are not designed for long-term performance in excessive heat or
stress and their contacts can corrode and locking tabs easily break off.
Here are some of the factors that can impact your network:
Environmental factor Impact
Ambient humidity and direct moisture Cable corrosion
Vibration Cable wear, disconnects
Temperature extremes Application failures, cable wear
Chemical exposure Cable corrosion
Dust Poor outlet/plug/connector contact, particularly with
fiber optic cable
Electromagnetic interface (EMI) Degraded transmission
3. White Paper
Fluke Networks www.flukenetworks.com3
The distances over which signal must be transmitted is another key difference. Industrial Ethernet cable may need to run
¼ of a mile or more as it is routed through a large plant, around hazards, and from machine to machine and switch to
switch. Unshielded twisted pair cable, typically used in offices, has a 100-meter maximum distance. While this specifica-
tion originated to separate user transmissions and prevent collisions, today the distance limitation is the result of power
transmission. Network Interface cards (NICs) are designed for 100 meters. Beyond this distance, extra power is required
and it generates noise that interferes with data transmission. Multimode fiber is sufficient for up to two kilometers.
For distances over 2-3 kilometers, singlemode fiber optic cable may be required. Yet fiber optic cable brings its own set of
requirements. The diameter of a single mode fiber is smaller than a red blood cell. Fingerprints, or even dust in the air can
sit on the fiber optic end-face, causing reflectance and inhibiting signal transmission.
Finally, something as basic as power can affect an Ethernet installation. Office-grade Ethernet components may not
function in an industrial environment powered by 24 or even 48 volts, with AC and DC sources. Industrial grade
components will probably be required.
A difference in the nature of the work: The need for determinism
In the industrial environment, the nature of the work being done and the functions of the devices are very different from
the office network. Lost traffic takes on much greater significance. In most office networks, the stakes are not nearly so
high if data is lost, and there are many ways to compensate for lost packets. At the least, a user can re-send a data file
that has been corrupted in transmission. If the office network is running a little slow, it is annoying and it impacts
personnel productivity, but people can usually work around it.
In the industrial world of high-speed production and precise processes, correct and timely delivery of communication is
extremely important. A data packet might contain an alert warning of excessive heat or even fire. It might be a command
to turn on a cooling system. Corrupted, lost, or untimely packets -whether delivered too fast or too slow– cause serious
consequences: production errors, reduced throughput, waste, and downtime. All these translate into significant costs.
For these reasons, industrial Ethernet must be “deterministic”. This means the network must guarantee that an event will
occur within a specified time period. This is not the rule in corporate environments and there was a time when this was
not so in the industrial world. Today it is mandatory.
Understanding Ethernet standards and ratings
Knowledge of some of the Ethernet standards and ratings that have evolved over the years can help you design a more
robust and resilient network.
Classify your environmental conditions with MICE tables
To describe possible environmental conditions within industrial sites, the Telecommunications Infrastructure Association
(TIA) has created Mechanical, Ingress, Climatic/Chemical, and Electromagnetic (MICE) tables. MICE Level 1 describes a
typical office environment. MICE 2 describes a slightly harsher setting. MICE 3 describes a heavy industrial environment.
4. White Paper
Fluke Networks www.flukenetworks.com4
Approximately 80% of environments are addressed by the tables, excepting only the most extreme or specialized
environments. The Mechanical section of each table provides values for shock/bump, vibration, tensile force, crush,
impact, and bending/flexing. Ingress specifies the size of particulates (dust). The Climatic/Chemical section provides
values for temperature, humidity, radiation, and liquid and gaseous pollution from common industrial contaminants.
Finally, the Electromagnetic section provides specific values for electrostatic discharge, radiated and conducted radio
frequency (RF), surge (transient ground potential difference) and magnetic field.
The MICE tables do not constitute a set of requirements for cabling, but they do provide a helpful context for evaluating
your specific environment and selecting cabling systems that are compatible. Also consider that your cabling run may
pass through multiple MICE environments. If you establish environmental boundaries, you can minimize the need for the
highest-rated cabling throughout your entire facility.
Determine the degree of protection offered by connectors, devices, and other equipment with the protection
ratings. An IP (Index of Protection) rating indicates the degree of protection offered by equipment. The rating is always
specified with the letters IP followed by two numbers. The first number indicates the degree of protection against solid
foreign bodies. The second number is the degree of water protection. A lower rating of IP 55, for example, indicates that
a device provides enough protection from dust particles and water spray that operation won’t be disrupted. A higher
rating of IP 68 indicates the device is dust-proof and can be immersed in water over time without adverse effects.
The commonly used RJ-45 connector in a typical patch cable is not IP rated. It is not designed to provide any protec-
tion from dust or to be at all waterproof. Ethernet cable in harsh environments will either require specially designed RJ45
connectors with protective sealed boots, or you’ll need to move up to another type of connector altogether such as the
M-12. With an IP-68 rating, the M-12 connector offers some of the highest levels of physical protection against solids and
liquids. A pharmaceutical wash-down room is a good example of an application that requires not only connectors with high
IP ratings, but also specially designed equipment enclosures that carry high IP ratings.

The Network
The biggest mistake plants make in installing an industrial network is thinking that the office network can be the same
network used for the production floor. You don’t want the variable traffic and address schemes of your corporate network
to interfere with the consistent, structured, and less variable nature of your production network. Corporate traffic may
bring down, or slow down, your production traffic and jeopardize the deterministic nature of your production network.
A VLAN (virtual local area network) is one way to segment network traffic. Set it up so that the corporate and production
networks can communicate with one other but not share the other’s highway. Think of it as two major highways with a
tunnel providing access between the two.
The second mistake is trying to save money by buying office-grade Ethernet switches. Industrial environments require
industrial-rated switches; they are designed to stand up to the rigors of the industrial world, and help the network run
more efficiently. In production, it’s critical to get information from point A to point B reliably. The end result of poor net-
work performance in an office may only be users’ PCs running slowly. On the production floor, the difference between
a communication being sent in four versus six seconds could be the difference between a high-speed bottling line working
or not. Or, in a sheet metal plant, it might determine whether or not the material is cut in the correct lengths.

The proper flow of information keeps the belt moving at exactly the right speed, and keeps the temperature consistent
over a 140-foot span.
Electrical signaling
The devices on the network such as switches can be impacted by many of the same issues that affect cabling. Harsh
electrical environments can cause transients, disturbances, and static discharge. Extreme humidity and temperature
changes, vibration, and inconsistent or inefficient power delivery can all disrupt signaling. Appropriately IP rated devices
can mitigate many of these problems.
Cabling infrastructure: Protecting the cable from exposure to hazards
In a typical data center, you’ll probably find a server with unshielded twisted-pair cables hanging from the back and
running unprotected to the ceiling; and that is perfectly fine. In an industrial environment, cables need to be protected
with plastic or metal conduit. It is acceptable to run Ethernet along the ceiling in open trays. But when those cables reach
the wall or anywhere they can be sprayed with water, get hot, or be hit by a lift truck, put it in conduit.
You also need to consider EMI shielding. For example, one machine might be filling bottles and another machine loading
them into the boxes. The Ethernet line needs to be separated and shielded from the EMI field that machines, cables,
motors, and transformers generate. Excessive electronic noise will interfere with signals. It usually manifests itself as
particular types of easily recognizable network errors, and indicates that the transmitted frame has been corrupted
somewhere along the path.
What can be done about it? UTP (unshielded twisted pair) cabling is by nature fairly immune to lower levels of EMI.
An opposite signal is transmitted on each leg of pair, and because the pair is located in the same place, any interference
is the same on both legs, effectively canceling out EMI. For higher levels of EMI, you can use a cabling type called
shielded twisted pair (STP, also known as CAT 5 cable). Or for even greater protection, use fiber optic cable, which is
immune to EMI.
Using enhanced, higher-rated cabling is not the only means of dealing with harsh environments. Consider using a combi-
nation of separation, isolation, and enhancement strategies. For example, when there is a risk of liquids, separation can be
achieved by running cabling in cable trays at ceiling height as opposed to on floor pathways. Isolation can be achieved by
using appropriate conduits or raceway, such as properly grounded metal conduit that helps isolate some EMI noise.
When operating under harsher conditions, take preventative measures such as regularly replacing patch cords and connec-
tors well before their rated life to help avoid downtime. By establishing and documenting the baseline of your network and
doing regularly scheduled preventative maintenance, you can not only keep your network running more reliably, but also
track down and correct problems more quickly when they do occur.
