Benefits of Ethernet Powerlink

Ethernet Powerlink is an open standard protocol that enables Ethernet to be used for real-time data communication. It was introduced by an Austrian automation company, B&R, in 2001. Its benefits and costs are described in this article. This technology enables industrial applications such as industrial automation and factory monitoring to use Ethernet as a communication medium. But how can an industrial site implement Ethernet Powerlink? The answer lies in the fact that powerlinks are widely used in industrial settings.

Ethernet Powerlink

The Ethernet POWERLINK Standardization Group has managed the development of an open, real-time protocol for standard Ethernet. It was first introduced by the Austrian automation company B&R in 2001. Since then, its use has grown from its humble beginnings as a simple way to connect two computers. Despite its limited use, the technology is now commonly used for industrial applications. Here are some benefits of Ethernet Powerlink. And read on to learn how it can benefit your business.

The OD is divided into sections. Section 0x1000-0x1FFF holds the parameters for communication objects. Sections 0x2000-5FFF are reserved for manufacturer-specific entries. Entries starting at 0x6000 contain device-specific objects. The Ethernet POWERLINK Specification specifies the communication parameters that are supported by POWERLINK devices. It also includes a CANopen device profile. This means that Ethernet POWERLINK devices can support Gigabit Ethernet, and vice versa.

Ethernet Powerlink scheduling mechanism

The Ethernet Powerlink (EPL) is a high-speed industrial backbone that operates with deterministic real-time characteristics. Its design is based on the CANopen protocol and reuses its basic principles, including the use of process and service data objects (PDOs) and isochronous phase. The EPL specification specifies communication parameters that must be supported by every POWERLINK device. If the device does not support EPL, it can be extended with CANopen device profiles.

The Managing Node is the master in the POWERLINK network. It polls controlled nodes cyclically and maintains network status by means of a scheduling mechanism. This occurs in the isochronous phase of the cycle, which is time-critical whereas the asynchronous phase is not. The isochronous phase is initiated by a Start of Cyclic (SoC) frame and ensures that all nodes synchronize, preventing collisions between Ethernet and TCP/IP communication.

Benefits of Ethernet Powerlink for newer sites

With ETHERNET Powerlink, you can monitor and diagnose all devices on your network. The protocol is deterministic and secure, and it provides a high level of performance and system reliability. It also uses a licensed-free standard that does not have any patents or intellectual property rights. All these benefits make it the perfect choice for newer sites. The advantages of Ethernet Powerlink are listed below. The benefits of Ethernet Powerlink are significant, but they are not the only reason to make the switch.

Unlike Ethernet, which cannot guarantee uninterrupted data transmission, Ethernet Powerlink is deterministic, allowing only one node to connect to the physical medium at a time. It uses an additional bus scheduling mechanism, which is a combination of isochronous and asynchronous phases. It avoids non-deterministic Ethernet behavior by managing the bandwidth between nodes and avoiding data collisions. Besides ensuring determinism, Ethernet Powerlink provides flexibility, since you can use it on any industrial PC or embedded chip.

Cost of implementing Ethernet Powerlink for newer sites

The ETHERNET Powerlink protocol is a standard Ethernet technology that provides real-time control and determinism. It also provides network security as standard. The attributes of Ethernet Powerlink are outlined in figure 1. These attributes include open standard, no patents, and no intellectual property rights. Therefore, it is free from any licensing costs, and will be a worthwhile investment. The following chart will show how much implementing Ethernet Powerlink will cost for newer sites.

In addition to addressing the need for real-time data transfer, Ethernet has limitations. It is prone to message inquiries and data collisions. The technology also has timing delays introduced by routers. Ethernet Powerlink solves these problems by maintaining determinism by ensuring that network access occurs only during certain time slots. This helps reduce network costs and speeds up factory commissioning. Furthermore, it allows for one motion controller to manage multiple sites.
