Website developed for control engineers and technicians.
Understanding the technology and architectures of Ethernet can be of great value as this communication becomes more common in a variety of industrial applications. From scada to PLC I/O, Ethernet is not just one network but can be many different networks in an industrial application. However, finding a location that can help simplify the technology and how it relates to industrial automation applications has been a challenge until now.
Ethernet Direct with a local office in Johannesburg www.ethernetdirect.co.za has established a reference library of information specifically oriented to industrial Ethernet. This library is not a collection of Ethernet terms or computer scientist definitions, but a comprehensive library written by control engineers for control engineers. It relates the use of industrial Ethernet to past communication techniques. Written by individuals who have spent the last 10 years applying Ethernet to control and PLC applications, this library is an invaluable tool for anyone designing or supporting Industrial Ethernet.
In the library members have access to:
* Ethernet terms and how they relate to industrial applications.
* Network architectures and recommendations.
* Industrial Ethernet software tools and their value.
* Understanding the proper use of VLANs.
* Filtering and how it could affect multicast traffic.
* Plant floor issues.
* Important organisations and their functions.
With over 100 diagrams and expert comments, this location provides a unique training platform. From individuals just starting to learn about Ethernet, to experienced Network professionals trying to understand the subtle differences when applying the technology to realtime control applications, this site offers something for everyone.
The following is one of the topics relating to network design that provides a great deal of insight. This is just one of many available to individuals who join this free support area:
10 common misconceptions about industrial Ethernet networks
1. Ethernet exists as a single network on the plant floor with everything connected to this common network.
2. Industrial devices with Ethernet connections all operate the same way.
3. Auto-negotiation is an effective method to simplify connections to a switch for all connected devices.
4. It is not important to organise devices on the network.
5. The MAC address is a unique identifier for every Ethernet device.
6. Physically isolating a network from the outside world prevents any viruses or worms from infecting the network.
7. The same principles applied to office Ethernet can be used on the plant side.
8. All outsource service providers can provide adequate response to communication issues on the plant floor.
9. Using higher power switches Layer 3 is better than using layer 2 for applications.
10. Multicast filtering will help keep automation networks running properly.

Introduction to Part 2 loop signatures and process transfer functions
Fieldbus & Industrial Networking
The previous series of loop signature articles dealt with the basics of control loop optimisation, and concentrated on troubleshooting and ‘SWAG’ tuning of simple processes. In this new series, consideration will be given to dealing practically with more difficult issues like interactive processes, and with processes with much more complex dynamics.
