Industrial Ethernet
Industrial Ethernet - The use of Ethernet as an industrial network is a subject for which still very little documentation is available. This publication focuses entirely on this type of usage of Ethernet, and how this relates to the operation of Ethernet. A difference between an office-user of Ethernet and an industrial user of Ethernet is that the former is not interested in (seemingly trivial) details of internal Ethernet operation, while the latter must sometimes know all the details in order to assure that the network operates correctly under all circumstances. Despite many publications in the trade press about industrial Ethernet, it is difficult to find relevant technical information void of marketing hype and commercial interests. This excellent 100 page publication addresses this - thanks to Rob Hulsebos.

This includes the original 10 Megabit per second (Mbps) system, 100 Mbps Fast Ethernet (802.3u), 1000 Mbps Gigabit Ethernet (802.3z/802.3ab), and 10 Gigabit Ethernet (802.3ae).
Industrial Ethernet Handbook for Engineers - Engineers working to understand the nuances of Ethernet topologies, interconnection schemes, and application guidelines will find HARTING’s Industrial Ethernet Handbook a valuable engineering reference source. The detailed, 168-page handbook covers the technical details of Ethernet, comparing it to other fieldbus systems, and explaining its Open System Interconnection (ISO/OSI) Reference Model. Its Annex details pertinent standards and application guidelines, such as EN, IEEE, IEC, UL, and HD/VDE. This Annex also contains an extensive bibliography on fieldbus and Ethernet technology, along with Internet links to other resources.
The HARTING Handbook explains:
- Open System Interconnection (ISO/OSI) Reference Model
- Comparison of Ethernet to other fieldbus systems
- Power over Ethernet (PoE) connectivity
- 26-page glossary of terms/acronyms
Ethernet Basics - This Industrial Ethernet Basics Guide defines all of the basic network building blocks like hubs, switches, routers, bridges, terminal servers and gateways; it explains issues in selecting cables for demanding applications, and issues regarding software drivers and network speed. It explains network design rules for hubs and repeaters; and it explains the 7-Layer networking model in plain English - from B&B Electronics.
Media Redundancy Concepts - High Availability in Industrial Ethernet - The general idea of media redundancy and redundant paths is almost as old as the use of Ethernet for industrial communications, and so is the dilemma that – by definition – Ethernet technology’s broadcast nature does not permit physical loops and therefore effectively forbids redundant communications paths. However, fault tolerance, which necessitates the use of redundant structures, is a vital basic requirement of very many automation systems. This means that the use of Ethernet for automation technology applications calls for protocols that are able to resolve the physical loops generated by the introduction of redundant pathways. To facilitate the use of redundant communications structures in office environments, the IEEE (Institute of Electrical and Electronics Engineers) specified the spanning tree protocol (STP), which was published in the 802.1D 1990 standard. For the first time this enabled all Ethernet switches to employ an algorithm to facilitate interconnected network structures, albeit with switchover times of the order of many tens of seconds. Further protocols based on the underlying STP mechanisms were subsequently developed, and these were better tailored to the specific requirements of an industrial environment, in particular with markedly reduced switchover times. This white paper will give you an overview of the current state of the technology and its solutions and also sketch a number of specific applications - from Belden.
Why 'Industrial Ethernet' is more than just 'Industrial' + 'Ethernet' - Justin Nga - The increasing use of digital equipment in industrial environments coupled with increased integration and data bandwidth requirements has led to growing adoption of Ethernet (IEEE 802.3) for communication in place of older serial-based communication systems. However, simply selecting ruggedised versions of Ethernet equipment originally designed for conventional IT environments will not create a true Industrial Ethernet network - from Belden and PACE.
Building Automation Migrates towards Ethernet and Wireless - James Hunt - Buildings are becoming more automated, but what kind of communication and control networks are needed? As building electrical installations gain greater sophistication, there is a corresponding growing requirement for extensive functional diversity, convenience and efficient operation of the increasingly large number of digital products that the average building now contains. This article reports on building automation requirements, and networking techniques used to carry out energy management and control tasks - from the Industrial Ethernet Book.
Industrial Ethernet : A Control Engineer’s Guide - As part of a continuing effort to make their organizations more efficient and productive, manufacturers are rapidly migrating to Industrial Ethernet technology.

Redundancy in EtherNet/IP systems - Alain Grenier - As with any Ethernet-based industrial protocol, in EtherNet/IP, redundancy-the repetition or duplication of messages to circumvent transmission errors-is required to maintain maximum uptime while still enabling the system to deal with minor outages and potential failures to the environment. Redundancy plays a critical role in determining the reliability of the entire system, from the very edge devices, through the network core, to the plant backbone - from ISA.

Power Over Ethernet - POE is a technology that provides electrical power to a Powered Device using conductors in a CAT5 cable. Power is delivered by means of a DC voltage and maximum current rating. Typical Power Sourcing Equipment devices are network switches. Even though there is a standard (IEEE 802.3af) there are a number of factors you should watch for as this technology emerges and evolves because as usual the devil is in the detail - from chipkin.com.
