The Differences Between Ethernet Powerlink and CompactCom 40-Series

In this article, you will learn about Ethernet Powerlink and CompactCom 40-series. In addition, you’ll learn about Ethernet Powerlink Scheduling Mechanism and Ethernet Powerlink Standardization Group. These two technologies are related, but are not the same. Despite their similarities, Ethernet Powerlinks differ in a number of important ways. We’ll examine each of them in turn to better understand their differences. In the end, you’ll understand why you should use Ethernet Powerlink in your business.

Ethernet Powerlink

Ethernet Powerlink is a real-time protocol for standard ethernet. It is managed by the Ethernet POWERLINK Standardization Group (EPSG). It was originally introduced by Austrian automation company B&R in 2001. Its benefits extend far beyond simple networking and control. EPSG enables real-time data exchange, and is the preferred protocol in industrial applications. It is based on an open and standardized protocol. Its real-time capabilities enable industrial applications to operate at much higher speeds than standard Ethernet.

Ethernet Powerlink CompactCom 40-series

The Ethernet Powerlink CompactCom 40-series is a multi-network industrial controller based on the HMS Anybus NP40 network processor. It enables fast communication between the host device and the network, supporting up to 1500 bytes of process data in each direction. It is available in brick, chip, and module form factors, allowing device manufacturers to select the level of integration they need without the need for customisation.

Ethernet Powerlink Scheduling Mechanism

The Ethernet Powerlink Scheduling Mechanism is responsible for the smooth functioning of POWERLINK networks. The POWERLINK protocol is an Industrial Real-Time Ethernet standard based on the IEEE 802.3 standard. POWERLINK networks utilize a Managing Node that is a master. This master polls the controlled nodes cyclically. The first phase is called the isochronous phase, while the next is called the asynchronous period. The asynchronous phase is not time-critical. The cycle begins with a Start of Cyclic (SoC) frame, which synchronizes all nodes and ensures determinism in hard real-time communication. The SoC frame is implemented in the POWERLINK data link layer.

Ethernet Powerlink Standardization Group

The Ethernet Powerlink Standardization Group (EPSG) is a technical association formed in June 2003. It aims to achieve high openness on the application layer by integrating CANopen communication and device profiles. This approach provides continuity from a simple sensor network to a fast motion control system. For developers, there are software tools that help you create POWERLINK devices. They are available from port GmbH. This association also coordinates the Ethernet Powerlink protocol, and supports both IEEE 802.3 and IEEE 802.11b/W.
