As customers continually search for faster and improved solutions for their industrial automation applications, many are discovering and choosing Industrial Ethernet for its ability to reduce expenses and increase communication capability.

What is Industrial Ethernet?

Ethernet itself is the computer networking technology generally used for local area networks (LANs) and is standardized in IEEE 802.3. Industrial Ethernet is the result of applying traditional Ethernet standards to industrialized applications. To make that possible, industrial grade components are used that can tolerate demanding conditions such as extreme temperatures, shock, vibration, and washdown applications.

What are the major benefits of Industrial Ethernet?

Industrial Ethernet benefits users by utilizing tools and techniques familiar to traditional office communication systems. However, through the use of rugged components, users may now apply Ethernet to industrial applications. This facilitates data transfer across the entire plant floor as well as plant-to-plant globally via secure network connections.

Industrial Ethernet supports a variety of topologies including star, line, device-level ring, and tree (shown below).

Industrial Ethernet


Turck provides a complete line of Industrial Ethernet products including modular and block I/O systems, in-cabinet and on-machine Ethernet I/O, decentralized control with programmable systems conforming to IEC 61131, and innovative technologies such as RFID and IO-Link.


EtherNet/IP is a communication protocol supported by the ODVA and is designed for use in industrial automation and process control applications. It takes the Common Industrial Protocol (CIP) and implements it onto the foundation of Ethernet. CIP envelops a wide-ranging suite of messages and services for a variety of applications, including safety, control, configuration and information. EtherNet/IP provides users with tools to deploy standard Ethernet technology for industrial applications.


PROFINET uses the same Ethernet as offices and IT departments. However, its capabilities have been ruggedized to meet the tougher conditions faced in industrial applications. PROFINET is often a first option due to its ability to be used in basically any function in industrial automation. Utilizing its integrated Ethernet based communication and supported by PROFIBUS International, PROFINET is able to satisfy a wide assortment of requirements.


Quite simply, Modbus TCP is the Modbus RTU protocol with a TCP interface running on Ethernet. TCP/IP refers to Transmission Control Protocol and Internet Protocol, which provides the transmission channel for Modbus TCP/IP messaging. Modbus TCP/IP is used often in industrial environments due to its ease of deployment and maintenance, and because it was developed specifically with industrial applications in mind.


EtherCAT stands for Ethernet for Control Automation Technology, with a goal to create the ability to apply Ethernet to automation applications that require very short and quick upload times. EtherCAT uses a unique approach known as "processing on the fly”, in which data is not received, processed, and copied in order, but rather processed while passing through the device, allowing EtherCAT to operate at higher speeds than other protocols. This "processing on the fly” principle also allows flexibility in topology and provides data in nearly real-time. EtherCAT is commonly used in any application that requires motion or motion control.

Multiprotocol Ethernet Products

Turck provides a complete line of Industrial Ethernet products, including on-machine, in-cabinet, block, and modular I/O. Turck offers Ethernet solutions where I/O can connect directly or indirectly to Ethernet. The most recent innovation is the Multiprotocol Industrial Ethernet concept. Turck’s innovative approach to Industrial Ethernet makes moving from another protocol or simply implementing a fieldbus for the first time plug-in simple. Turck’s Multiprotocol products are self-configuring and offer a seamless transition to Ethernet, whatever Industrial Ethernet protocol that may be.
