Industrial Ethernet ( IE ) is the use of Ethernet in an industrial environment with protocols that provide determinism and real-time control. Protocols for industrial Ethernet include EtherCAT , EtherNet/IP , PROFINET , POWERLINK , SERCOS III , CC-Link IE , and Modbus TCP . Many industrial Ethernet protocols use a modified media access control (MAC) layer to provide low latency and determinism. Some microprocessors provide industrial Ethernet support.

59-506: Industrial Ethernet can also refer to the use of standard Ethernet protocols with rugged connectors and extended temperature switches in an industrial environment, for automation or process control . Components used in plant process areas must be designed to work in harsh environments of temperature extremes, humidity, and vibration that exceed the ranges for information technology equipment intended for installation in controlled environments. The use of fiber-optic Ethernet variants reduces

118-482: A body of water vapor) in steam engines , in regard to the system's ability to do work when heat is applied to it. The working substance could be put in contact with either a boiler, a cold reservoir (a stream of cold water), or a piston (on which the working body could do work by pushing on it). In 1850, the German physicist Rudolf Clausius generalized this picture to include the concept of the surroundings and began to use

177-439: A broad math and science foundation spanning chemistry , physics , mechanics (i.e., statics, kinematics, and dynamics), materials science , computer science , electronics/circuits, engineering design , and the standard range of engineering mathematics (i.e., calculus , linear algebra , differential equations , statistics ). For any engineering undergraduate program to be accredited, regardless of concentration, it must cover

236-601: A car, a coffeemaker , or Earth . A closed system exchanges energy, but not matter, with its environment; like a computer or the project Biosphere 2 . An isolated system exchanges neither matter nor energy with its environment. A theoretical example of such a system is the Universe . An open system can also be viewed as a bounded transformation process, that is, a black box that is a process or collection of processes that transform inputs into outputs. Inputs are consumed; outputs are produced. The concept of input and output here

295-777: A largely similar span of such foundational work – which also overlaps heavily with the content tested on one or more engineering licensure exams in most jurisdictions. The coursework specific to IE entails specialized courses in areas such as optimization , applied probability , stochastic modeling, design of experiments , statistical process control , simulation , manufacturing engineering , ergonomics / safety engineering , and engineering economics . Industrial engineering elective courses typically cover more specialized topics in areas such as manufacturing , supply chains and logistics , analytics and machine learning , production systems , human factors and industrial design , and service systems . Systems A system

354-444: A major defect: they must be premised on one or more fundamental assumptions upon which additional knowledge is built. This is in strict alignment with Gödel's incompleteness theorems . The Artificial system can be defined as a "consistent formalized system which contains elementary arithmetic". These fundamental assumptions are not inherently deleterious, but they must by definition be assumed as true, and if they are actually false then

413-458: A practical industrial Ethernet system must also provide interoperability of higher levels of the OSI model . An industrial network must provide security both from intrusions from outside the plant, and from inadvertent or unauthorized use within the plant. When an industrial network must connect to an office network or external networks, a firewall system can be inserted to control exchange of data between

472-432: A process, system, or organization operates. In fact, the industrial in industrial engineering means the industry in its broadest sense. People have changed the term industrial to broader terms such as industrial and manufacturing engineering , industrial and systems engineering , industrial engineering and operations research , industrial engineering and management . Industrial engineering has many sub-disciplines,

531-458: A separate program in 1909 through the efforts of Hugo Diemer . The first doctoral degree in industrial engineering was awarded in 1933 by Cornell University . In 1912, Henry Laurence Gantt developed the Gantt chart , which outlines actions the organization along with their relationships. This chart opens later form familiar to us today by Wallace Clark . With the development of assembly lines ,

590-582: A system understanding its kind is crucial, and defined natural and designed , i. e. artificial, systems. For example, natural systems include subatomic systems, living systems , the Solar System , galaxies , and the Universe , while artificial systems include man-made physical structures, hybrids of natural and artificial systems, and conceptual knowledge. The human elements of organization and functions are emphasized with their relevant abstract systems and representations. Artificial systems inherently have

649-456: Is George Boole 's Boolean operators. Other examples relate specifically to philosophy, biology, or cognitive science. Maslow's hierarchy of needs applies psychology to biology by using pure logic. Numerous psychologists, including Carl Jung and Sigmund Freud developed systems that logically organize psychological domains, such as personalities, motivations, or intellect and desire. In 1988, military strategist, John A. Warden III introduced

708-495: Is a general consensus among historians that the roots of the industrial engineering profession date back to the Industrial Revolution . The technologies that helped mechanize traditional manual operations in the textile industry including the flying shuttle , the spinning jenny , and perhaps most importantly the steam engine generated economies of scale that made mass production in centralized locations attractive for

767-507: Is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole. A system, surrounded and influenced by its environment , is described by its boundaries, structure and purpose and is expressed in its functioning. Systems are the subjects of study of systems theory and other systems sciences . Systems have several common properties and characteristics, including structure, function(s), behavior and interconnectivity. The term system comes from

826-534: Is a hardware system, software system , or combination, which has components as its structure and observable inter-process communications as its behavior. There are systems of counting, as with Roman numerals , and various systems for filing papers, or catalogs, and various library systems, of which the Dewey Decimal Classification is an example. This still fits with the definition of components that are connected together (in this case to facilitate

885-413: Is also a significant milestone in the field. Engineering is traditionally decompositional. To understand the whole of something, it is first broken down into its parts. One masters the parts, then puts them back together to create a better understanding of how to master the whole. The approach of industrial and systems engineering (ISE) is opposite; any one part cannot be understood without the context of

944-533: Is an engineering profession that is concerned with the optimization of complex processes , systems , or organizations by developing, improving and implementing integrated systems of people, money, knowledge, information and equipment. Industrial engineering is central to manufacturing operations. Industrial engineers use specialized knowledge and skills in the mathematical, physical , and social sciences , together with engineering analysis and design principles and methods, to specify, predict, and evaluate

1003-432: Is different in that it is based on discrete variable math, whereas all other engineering is based on continuous variable math. We emphasize the use of linear algebra and difference equations, as opposed to the use of differential equations which are so prevalent in other engineering disciplines. This emphasis becomes evident in optimization of production systems in which we are sequencing orders, scheduling batches, determining

1062-434: Is generally credited as being the father of the industrial engineering discipline. He earned a degree in mechanical engineering from Stevens Institute of Technology and earned several patents from his inventions. His books, Shop Management and The Principles of Scientific Management , which were published in the early 1900s, were the beginning of industrial engineering. Improvements in work efficiency under his methods

1121-478: Is the branch of Engineering most closely related to human resources in that we apply social skills to work with all types of employees, from engineers to salespeople to top management. One of the main focuses of an Industrial Engineer is to improve the working environments of people – not to change the worker, but to change the workplace." "All engineers, including Industrial Engineers, take mathematics through calculus and differential equations. Industrial Engineering

1180-448: Is very broad. For example, an output of a passenger ship is the movement of people from departure to destination. A system comprises multiple views . Human-made systems may have such views as concept, analysis , design , implementation , deployment, structure, behavior, input data, and output data views. A system model is required to describe and represent all these views. A systems architecture, using one single integrated model for

1239-557: The 8P8C connectors commonly used in homes and businesses. Programmable logic controllers (PLCs) communicate using one of several possible open or proprietary protocols, such as EtherNet/IP , EtherCAT , Modbus , Sinec H1 , Profibus , CANopen , DeviceNet or FOUNDATION Fieldbus . The idea to use standard Ethernet makes these systems more interoperable . Some of the advantages over other types of industrial network include: Difficulties of using industrial Ethernet include: Industrial engineering Industrial engineering

1298-519: The Latin word systēma , in turn from Greek σύστημα systēma : "whole concept made of several parts or members, system", literary "composition". In the 19th century, the French physicist Nicolas Léonard Sadi Carnot , who studied thermodynamics , pioneered the development of the concept of a system in the natural sciences . In 1824, he studied the system which he called the working substance (typically

1357-494: The Industrial Revolution to establish and implement factory systems. The efforts of James Watt and Matthew Boulton led to the first integrated machine manufacturing facility in the world, including the application of concepts such as cost control systems to reduce waste and increase productivity and the institution of skills training for craftsmen. Charles Babbage became associated with industrial engineering because of

1416-661: The ability to interact with local and remote operators. A subsystem description is a system object that contains information defining the characteristics of an operating environment controlled by the system. The data tests are performed to verify the correctness of the individual subsystem configuration data (e.g. MA Length, Static Speed Profile, …) and they are related to a single subsystem in order to test its Specific Application (SA). There are many kinds of systems that can be analyzed both quantitatively and qualitatively . For example, in an analysis of urban systems dynamics , A . W. Steiss defined five intersecting systems, including

1475-462: The allocation and scarcity of resources. The international sphere of interacting states is described and analyzed in systems terms by several international relations scholars, most notably in the neorealist school . This systems mode of international analysis has however been challenged by other schools of international relations thought, most notably the constructivist school , which argues that an over-large focus on systems and structures can obscure

1534-526: The bachelor, masters, and doctoral level. In the United States, the undergraduate degree earned is either a bachelor of science (B.S.) or a bachelor of science and engineering (B.S.E.) in industrial engineering (IE). In South Africa , the undergraduate degree is a bachelor of engineering (BEng). Variations of the title include Industrial & Operations Engineering (IOE), and Industrial & Systems Engineering (ISE or ISyE). The typical curriculum includes

1593-547: The concepts he introduced in his book On the Economy of Machinery and Manufacturers which he wrote as a result of his visits to factories in England and the United States in the early 1800s. The book includes subjects such as the time required to perform a specific task, the effects of subdividing tasks into smaller and less detailed elements, and the advantages to be gained from repetitive tasks. Eli Whitney and Simeon North proved

1652-410: The description of multiple views, is a kind of system model. A subsystem is a set of elements, which is a system itself, and a component of a larger system. The IBM Mainframe Job Entry Subsystem family ( JES1 , JES2 , JES3 , and their HASP / ASP predecessors) are examples. The main elements they have in common are the components that handle input, scheduling, spooling and output; they also have

1711-772: The development of decision support systems in supply such as material requirements planning (MRP), one can emphasize the timing issue (inventory, production, compounding, transportation, etc.) of industrial organization. Israeli scientist Dr. Jacob Rubinovitz installed the CMMS program developed in IAI and Control-Data (Israel) in 1976 in South Africa and worldwide. In the 1970s, with the penetration of Japanese management theories such as Kaizen and Kanban , Japan realized very high levels of quality and productivity. These theories improved issues of quality, delivery time, and flexibility. Companies in

1770-399: The distinction between them is often elusive. An economic system is a social institution which deals with the production , distribution and consumption of goods and services in a particular society . The economic system is composed of people , institutions and their relationships to resources, such as the convention of property . It addresses the problems of economics , like

1829-408: The elements of human motion into 18 basic elements called therbligs . This development permitted analysts to design jobs without knowledge of the time required to do a job. These developments were the beginning of a much broader field known as human factors or ergonomics . In 1908, the first course on industrial engineering was offered as an elective at Pennsylvania State University , which became

1888-635: The environment in which the equipment must operate. Factory equipment must tolerate a wider range of temperature, vibration, physical contamination and electrical noise than equipment installed in dedicated information-technology wiring closets . Since critical process control may rely on an Ethernet link, economic cost of interruptions may be high and high availability is therefore an essential criterion. Industrial Ethernet networks must interoperate with both current and legacy systems, and must provide predictable performance and maintainability. In addition to physical compatibility and low-level transport protocols,

1947-399: The factory of Henry Ford (1913) accounted for a significant leap forward in the field. Ford reduced the assembly time of a car from more than 700 hours to 1.5 hours. In addition, he was a pioneer of the economy of the capitalist welfare ("welfare capitalism") and the flag of providing financial incentives for employees to increase productivity. In 1927, the then Technische Hochschule Berlin

2006-486: The feasibility of the notion of interchangeable parts in the manufacture of muskets and pistols for the US Government. Under this system, individual parts were mass-produced to tolerances to enable their use in any finished product. The result was a significant reduction in the need for skill from specialized workers, which eventually led to the industrial environment to be studied later. Frederick Taylor (1856–1915)

2065-513: The first time. The concept of the production system had its genesis in the factories created by these innovations. It has also been suggested that perhaps Leonardo da Vinci was the first industrial engineer because there is evidence that he applied science to the analysis of human work by examining the rate at which a man could shovel dirt around the year 1500. Others also state that the industrial engineering profession grew from Charles Babbage’s study of factory operations and specifically his work on

2124-404: The flow of information). System can also refer to a framework, aka platform , be it software or hardware, designed to allow software programs to run. A flaw in a component or system can cause the component itself or an entire system to fail to perform its required function, e.g., an incorrect statement or data definition . In engineering and physics , a physical system is the portion of

2183-507: The interaction of human beings with machines, materials, information, procedures and environments in such developments and in designing a technological system. Industrial engineering degrees accredited within any member country of the Washington Accord enjoy equal accreditation within all other signatory countries, thus allowing engineers from one country to practice engineering professionally in any other. Universities offer degrees at

2242-416: The manufacture of straight pins in 1832 . However, it has been generally argued that these early efforts, while valuable, were merely observational and did not attempt to engineer the jobs studied or increase overall output. Adam Smith's concepts of Division of Labour and the "Invisible Hand" of capitalism introduced in his treatise The Wealth of Nations motivated many of the technological innovators of

2301-988: The most common of which are listed below. Although there are industrial engineers who focus exclusively on one of these sub-disciplines, many deals with a combination of them such as supply chain and logistics, and facilities and energy management. Methods engineering Facilities engineering & energy management Financial engineering Energy engineering Human factors & safety engineering Information systems engineering & management Manufacturing engineering Operations engineering & management Operations research & optimization Policy planning Production engineering Quality & reliability engineering Supply chain management & logistics Systems engineering & analysis Systems simulation Related disciplines Organization development & change management Behavioral economics Industrial engineers study

2360-454: The networks. This network separation preserves the performance and reliability of the industrial network. Industrial environments are often much harsher, often subject to oil sprays, water sprays, and physical vibrations, so often industrial Ethernet requires a more rugged and watertight connector on one or both ends of the Cat 5 or Cat 6 cable , such as M12 connectors or M8 connectors, rather than

2419-464: The notion of organizations as systems in his book The Fifth Discipline . Organizational theorists such as Margaret Wheatley have also described the workings of organizational systems in new metaphoric contexts, such as quantum physics , chaos theory , and the self-organization of systems . There is also such a thing as a logical system . An obvious example is the calculus developed simultaneously by Leibniz and Isaac Newton . Another example

2478-412: The number of materials handling units, arranging factory layouts, finding sequences of motions, etc. As, Industrial Engineers, we deal almost exclusively with systems of discrete components." While originally applied to manufacturing , the use of industrial in industrial engineering can be somewhat misleading, since it has grown to encompass any methodical or quantitative approach to optimizing how

2537-400: The physical subsystem and behavioral system. For sociological models influenced by systems theory, Kenneth D. Bailey defined systems in terms of conceptual , concrete , and abstract systems, either isolated , closed , or open . Walter F. Buckley defined systems in sociology in terms of mechanical , organic , and process models . Bela H. Banathy cautioned that for any inquiry into

2596-501: The problems of electrical noise and provides electrical isolation. Some industrial networks emphasized deterministic delivery of transmitted data, whereas Ethernet used collision detection which made transport time for individual data packets difficult to estimate with increasing network traffic. Typically, industrial uses of Ethernet employ full-duplex standards and other methods so that collisions do not unacceptably influence transmission times. Industrial use requires consideration of

2655-624: The recovery of Japan after the war. The American Institute of Industrial Engineering was formed in 1948. The early work by F. W. Taylor and the Gilbreths was documented in papers presented to the American Society of Mechanical Engineers as interest grew from merely improving machine performance to the performance of the overall manufacturing process, most notably starting with the presentation by Henry R. Towne (1844–1924) of his paper The Engineer as An Economist (1886). From 1960 to 1975, with

2714-462: The results obtained from systems and processes. Several industrial engineering principles are followed in the manufacturing industry to ensure the effective flow of systems, processes, and operations. These include: These principles allow the creation of new systems , processes or situations for the useful coordination of labor , materials and machines and also improve the quality and productivity of systems, physical or social. Depending on

2773-405: The role of individual agency in social interactions. Systems-based models of international relations also underlie the vision of the international sphere held by the liberal institutionalist school of thought, which places more emphasis on systems generated by rules and interaction governance, particularly economic governance. In computer science and information science , an information system

2832-440: The subspecialties involved, industrial engineering may also overlap with, operations research , systems engineering , manufacturing engineering , production engineering , supply chain engineering , management science , engineering management , financial engineering , ergonomics or human factors engineering , safety engineering , logistics engineering , quality engineering or other related capabilities or fields. There

2891-1207: The system is not as structurally integral as is assumed (i.e. it is evident that if the initial expression is false, then the artificial system is not a "consistent formalized system"). For example, in geometry this is very evident in the postulation of theorems and extrapolation of proofs from them. George J. Klir maintained that no "classification is complete and perfect for all purposes", and defined systems as abstract, real, and conceptual physical systems , bounded and unbounded systems , discrete to continuous, pulse to hybrid systems , etc. The interactions between systems and their environments are categorized as relatively closed and open systems . Important distinctions have also been made between hard systems—–technical in nature and amenable to methods such as systems engineering , operations research, and quantitative systems analysis—and soft systems that involve people and organizations, commonly associated with concepts developed by Peter Checkland and Brian Wilson through soft systems methodology (SSM) involving methods such as action research and emphasis of participatory designs. Where hard systems might be identified as more scientific ,

2950-552: The system. There are natural and human-made (designed) systems. Natural systems may not have an apparent objective but their behavior can be interpreted as purposeful by an observer. Human-made systems are made with various purposes that are achieved by some action performed by or with the system. The parts of a system must be related; they must be "designed to work as a coherent entity"—otherwise they would be two or more distinct systems. Most systems are open systems , exchanging matter and energy with their respective surroundings; like

3009-462: The term working body when referring to the system. The biologist Ludwig von Bertalanffy became one of the pioneers of the general systems theory . In 1945 he introduced models, principles, and laws that apply to generalized systems or their subclasses, irrespective of their particular kind, the nature of their component elements, and the relation or 'forces' between them. In the late 1940s and mid-50s, Norbert Wiener and Ross Ashby pioneered

3068-1003: The universe that is being studied (of which a thermodynamic system is one major example). Engineering also has the concept of a system referring to all of the parts and interactions between parts of a complex project. Systems engineering is the branch of engineering that studies how this type of system should be planned, designed, implemented, built, and maintained. Social and cognitive sciences recognize systems in models of individual humans and in human societies. They include human brain functions and mental processes as well as normative ethics systems and social and cultural behavioral patterns. In management science , operations research and organizational development , human organizations are viewed as management systems of interacting components such as subsystems or system aggregates, which are carriers of numerous complex business processes ( organizational behaviors ) and organizational structures. Organizational development theorist Peter Senge developed

3127-463: The use of mathematics to study systems of control and communication , calling it cybernetics . In the 1960s, Marshall McLuhan applied general systems theory in an approach that he called a field approach and figure/ground analysis , to the study of media theory . In the 1980s, John Henry Holland , Murray Gell-Mann and others coined the term complex adaptive system at the interdisciplinary Santa Fe Institute . Systems theory views

3186-509: The west realized the great impact of Kaizen and started implementing their own continuous improvement programs. W. Edwards Deming made significant contributions in the minimization of variance starting in the 1950s and continuing to the end of his life. In the 1990s, following the global industry globalization process, the emphasis was on supply chain management and customer-oriented business process design. The theory of constraints , developed by Israeli scientist Eliyahu M. Goldratt (1985),

3245-868: The whole system. Changes in one part of the system affect the entire system, and the role of a single part is to better serve the whole system. Also, industrial engineering considers the human factor and its relation to the technical aspect of the situation and all of the other factors that influence the entire situation, while other engineering disciplines focus on the design of inanimate objects. "Industrial Engineers integrate combinations of people, information, materials, and equipment that produce innovative and efficient organizations. In addition to manufacturing, Industrial Engineers work and consult in every industry, including hospitals, communications, e-commerce, entertainment, government, finance, food, pharmaceuticals, semiconductors, sports, insurance, sales, accounting, banking, travel, and transportation." "Industrial Engineering

3304-401: The world as a complex system of interconnected parts. One scopes a system by defining its boundary ; this means choosing which entities are inside the system and which are outside—part of the environment . One can make simplified representations ( models ) of the system in order to understand it and to predict or impact its future behavior. These models may define the structure and behavior of

3363-405: Was based on improving work methods, developing of work standards, and reduction in time required to carry out the work. With an abiding faith in the scientific method, Taylor did many experiments in machine shop work on machines as well as men. Taylor developed "time study" to measure time taken for various elements of a task and then used the study observations to reduce the time further. Time study

3422-406: Was done for the improved method once again to provide time standards which are accurate for planning manual tasks and also for providing incentives. The husband-and-wife team of Frank Gilbreth (1868–1924) and Lillian Gilbreth (1878–1972) was the other cornerstone of the industrial engineering movement whose work is housed at Purdue University School of Industrial Engineering. They categorized

3481-399: Was the first German university to introduce the degree. The course of studies developed by Willi Prion was then still called Business and Technology and was intended to provide descendants of industrialists with an adequate education. Comprehensive quality management system ( Total quality management or TQM) developed in the forties was gaining momentum after World War II and was part of
