Understanding the technology and architectures of Ethernet can be of great value as this communication platform 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.
To facilitate a good understanding of the technology, Ethernet Direct 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 a valuable tool for anyone designing or supporting Industrial Ethernet.
The library provides 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.
* Common issues that are happening on the plant floor.
* Important organisations and their functions.
With over 100 diagrams and expert comments, this library 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 topic areas relating to network design that will provide a great deal of insight. This is just one of many areas available to individuals who join this free support area:
Ten most 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 my network from the outside world prevents any viruses or worms from infecting my network.
7. The same principle applied to our office Ethernet can be used on the plant side.
8. Outsource service providers can provide adequate response to communication issues on the plant floor.
9. Using higher power layer 3 switches is better than using layer 2 for applications.
10. Multicast filtering will help keep automation networks running properly.
