Ethernet Powerlink is an open protocol that was introduced by Austrian automation company B&R in 2001. It is a real-time protocol for standard Ethernet. Its real-time features make it ideal for implementing applications with hard-real-time requirements. It has numerous advantages over non-switched Ethernet, including reduced latency and higher bandwidth. Here, we will explore some of its key features. Here, we will explore how this technology can benefit your business.
Ethernet Powerlink is a real-time protocol for standard Ethernet
Ethernet Powerlink is a real-time LAN protocol developed by B&R that provides real-time properties for motion applications. It is managed by the ETHERNET Powerlink Standardization Group and uses open software to ensure high-speed data transfer. In addition to its real-time properties, Ethernet Powerlink can be configured for specific response times. As a result, it can provide higher levels of performance for different applications.
It prevents CSMA/CD mechanism of non-switched Ethernet
Powerlinks prevent the CSMA/CD mechanism of non-Switch Ethernet by using an asynchronous protocol called asymmetric multicast. In this protocol, error messages are sent to all participants in a collision domain in order to prevent the transmission of a data packet from becoming corrupted. Asymmetric multicast allows for the transmission of many data packets at once.
It is suitable for implementing applications with hard real-time requirements
For implementing applications with high-performance, hard real-time requirements, Powerlink has a variety of options. Its high-performance design features a flexible application interface based on the DS 301 CANopen communication profile specified by CAN in Automation. With its low jitter and low latency, Powerlinks is ideal for applications requiring hard-real-time performance.
It was developed at the field-device level
Powerlinks are communications protocols that provide field devices with high levels of flexibility and performance. Its core technology, Ethernet, has been enhanced with widely supported CANopen device profiles. By combining Ethernet and CANopen, manufacturers can integrate field devices and motion control systems on the factory floor. CANopen profiles describe the operational behavior of positioning drives, providing versatile and proven solutions from many manufacturers. A wide range of field devices is supported by Ethernet Powerlink.
It is a software-based solution
POWERLINK is an advanced communication technology, which can handle large volumes of data in real-time. This communication technology is ideal for applications that require hard-real-time requirements in the us range, but still need the flexibility of CANopen. In the software-based solution, the POWERLINK interface replaces a host of hardware components. It also allows users to integrate smart sensing solutions. The advantages of POWERLINK include low cost and high flexibility.
It is 100% compliant with IEEE 802.3 Ethernet standard
POWERLINK is a software-based solution that is fully compliant with the IEEE 802.3 Ethernet standard. It does not use any proprietary hardware components, so it allows users to benefit from Ethernet technology while using standardized diagnostics tools. Unlike other Ethernet networking systems, POWERLINK utilizes a mixed polling and time-slot procedure to synchronize the communication cycle. The second phase of a POWERLINK communication cycle involves the exchange of payload data between nodes.
