An Introduction to Ethernet Powerlink

LANs have become increasingly important in the production and management of industrial products. To help make the transition easier, we’ve written an introductory article on Ethernet Powerlink and its implementation. POWERLINK stands for Ethernet Powerlink, and is an open protocol managed by the Ethernet POWERLINK Standardization Group. Its name derives from an Austrian automation company that first introduced it in 2001. Powerlinks are essentially a high-speed communication link that uses standard Ethernet to transmit information between machines.


POWERLINKS are real-time Ethernet protocol systems that are compatible with standard Ethernet. The Ethernet POWERLINK Standardization Group manages this protocol, which was first introduced in 2001 by Austrian automation company B&R. Ethernet Powerlinks can connect up to four devices and transmit data up to one kilometer. Its versatility makes it a viable option for many industries. Unlike traditional CAT-i or CAT-v networks, POWERLINKS do not require a separate power source, so it can be installed in almost any location.

Ethernet Powerlink

The real-time protocol Ethernet Powerlink is a real-time interface for standard Ethernet. It is an open protocol managed by the Ethernet POWERLINK Standardization Group. B&R, an Austrian automation company, first introduced Ethernet Powerlink in 2001. Since then, it has been widely adopted by manufacturers and developers to automate a variety of processes. Its name stems from the fact that it is able to transfer high-speed data from a computer to a device without a wire.

Ethernet Powerlink Scheduling Mechanism

The Ethernet Powerlink Scheduling Mechanism is an additional bus scheduler that imposes a time slot for critical data transmission. In the isochronous phase, the Managing Node controls the timing in the network and authorizes individual nodes to send data. Asynchronous data traffic can transmit during the remaining cycle time. Ethernet Powerlink is a subset of PROFINET, which comes in two flavors: RT for soft real-time performance and IRT for hard real-time performance. It is open to both Ethernet and CANopen networks.

Ethernet Powerlink Implementation Guide

Ethernet Powerlink is a protocol for connecting industrial devices and equipment. The protocol is based on the CANopen standard and is designed to support cross-traffic and hot-plugging. It also features a standardized communication profile for process and service data objects. The EPSG has been working closely with other organizations to promote the use of Ethernet for industrial automation. The EPSG also has working groups for safety, technology, marketing, and certification.

Ethernet Powerlink Testing

Ethernet Powerlink is a protocol that allows devices in a network to share data. It accepts an 8P8C connector, which is commonly referred to as an RJ45, or an M12 connector. In order to perform Ethernet Powerlink testing, you will need the necessary equipment. Ethernet analysis hardware can help you to collect high-precision network traces.
