Powerlinks are Ethernet communications standards for real-time applications. They are compatible with the IAONA Industrial Ethernet Planning and Installation Guide, a guide for clean cabling of industrial networks. These networks are used to deliver personalized and always-on messaging through dynamic and visually attractive advertisements. This article will discuss the benefits of powerlinks. You can also learn about the protocol’s compatibility with existing industrial networks. For more information, please refer to the IEEE 1588 reference manual.
Ethernet Powerlink is a real-time protocol for standard Ethernet
ETHERNET Powerlink is a real-time protocol developed by the IEEE to facilitate industrial automation and process control applications. It provides a comprehensive view of all devices on the network and allows data to be transferred between standard applications, data bases, and process control systems. Its isochronous communication structure facilitates device diagnosis and upgrades, and allows for cross-traffic control and hot-plugging.
POWERLINK is a software-based solution that fully complies with IEEE 802.3 Ethernet standards. It has no proprietary hardware and no patented hardware. It preserves the benefits of Ethernet technology and enables users to continue using standard Ethernet hardware components and diagnostic tools. It relies on mixed polling and a time-slot procedure to transmit and receive data. Unlike Ethernet, POWERLINK is open and free.
It is used to implement applications with hard real-time requirements
For example, Powerlink is used to implement applications with hard real time requirements. These applications must transmit data in a specific time frame, or they can have catastrophic consequences. Typical examples are flight and train control systems. Errors in these systems can cause injury and even death. Fortunately, the Ethernet POWERLINK standard has been designed with this in mind. Below, we’ll discuss the key features of Powerlink and its importance to hard real-time systems.
Industrial Ethernet standards are ideally suited for hard real-time communication. These standards are IEEE 1588-compliant and were developed for highly deterministic applications. They also require extensions, such as CIP Motion and CIP Sync. These protocols protect against jitter, resulting in deterministic behavior. Fortunately, Ethernet and Powerlinks also support isochronous real-time communication.
It is compatible with IAONA’s Industrial Ethernet Planning and Installation Guide for clean cabling of industrial networks
When cabling for industrial networks, it is important to consider the physical environment. Using fiber optic cable allows links to extend beyond 100 m and copper links can be extended to several kilometers. Copper links with lower bitrates can be longer, but must be limited to the length specified by the communication parameters. It is also important to consider the building infrastructure and the electromagnetic environment in which the cabling will be installed.
The Installation Guide incorporates provisions from other Standards. References are cited in the text at appropriate locations. Publications are listed with dates, if applicable. The dated references refer to subsequent revisions; undated references refer to the most recent edition of the publication. In the event of incompatibility, it may be necessary to use other connections.
