Increase comprehension
This online book, “A comprehensible guide to industrial Ethernet” by Wilfried Voss, explains the basics of various protocols, such as Ethernet/IP, Modbus/TCP, EtherCAT, Ethernet Powerlink, ProfiNet and Sercos III. It covers challenges and motivation for industrial Ethernet, basics and advantages of fieldbus systems, OSI reference model, Ethernet TCP/IP basics and real-time control.

Two videos + links to more
This eight-minute video, “What is Ethernet?,” covers the IEEE 802.3 standard, local-area networking (LAN), physical layer, twisted-pair cabling, RJ-45 connectors and other essential aspects of Ethernet.
It's also linked to several other videos, including, “What is fieldbus?,” which covers its group of communication protocols. In addition, there are also links to videos about Modbus, DeviceNet, Profibus/Profinet, EtherCAT, AS-Interface, IO Link and others.
Fieldbuses in a nutshell
This 3.5-minute video, “Basics of a fieldbus control network,” covers sensor, device and control bus networks, and how they interact with programmable logic controllers (PLC), human-machine interfaces (HMI), smart instruments and enterprise bus networks.
Get industrial on the plant-floor
This online article, “Industrial Ethernet explained,” covers many strategies for hardening and protecting Ethernet for use on plant-floors and other harsh environments, such as deploying M-12 cables and connectors, and using Power over Ethernet (PoE), Profinet and several other communication protocols.
All about Profinet and Profinet
This 222-page book, “Catching the process fieldbus” by James Powell and Henry Vandelinde, provides a comprehensive look at bus networks, Profibus and Profinet protocols, physical layers and network components, installation design, commissioning, asset management and network health.
Talking to variable-speed drives
This 51-minute video, “Weg webinar—fieldbus communication for variable-speed drives,” covers controls, physical layers and protocols, RS-485, Modbus and Modbus TCP/IP, and CANopen and BACnet protocols.
Foundations of foundation fieldbus
This 44-page paper, “Foundation fieldbus,” is relatively dated, but it still provides a good introduction to the protocol’s history, organization, device approval, performance features, physical layer, communications, application layer and other concepts.
Six reasons for protocols
This blog post, “Six reasons to consider EtherNet/IP and Profinet for your process” by Steve Kannengieszer, examines the two protocols, presents a chart comparing the capabilities of eight of the primary Ethernet and fieldbus protocols, and also provides a short video about deploying EtherNet/IP or Profinet in a thermal mass flowmeter.
Best of before-and organizations
The previous incarnation of this column, “Fieldbus, Ethernet networks explained,” contains the usual resources, but it also includes links to most of the fieldbus organizations, such as EtherCAT, PI North America, FieldComm Group and ODVA.
