What You Need to Know About Powerlinks

If you’re a newcomer to the world of POWERLINK, you might be wondering what it is and how it works. Fortunately, this article will answer your questions about POWERLINKs, the CompactCom 40-series, and POWERLINK SCHEDULE MECHANISM. We’ll also cover the benefits of POWERLINK and what they can do for your business. Listed below are a few of the most important things to know about POWERLINKs.


Powerlinks are a real-time protocol based on the Ethernet standard. They’re open standards managed by the Ethernet POWERLINK Standardization Group. The Austrian automation company B&R introduced them in 2001. They are a simple and reliable way to communicate between devices, such as motors and pumps. This article will discuss the benefits of using POWERLINKS. This article explains what a POWERLINK is and how it differs from a traditional serial connection.

The most common example of a POWERLINK communication is in a roundtable discussion. In this type of discussion, a moderator invites participants to speak at specified intervals. The system prevents simultaneous speaking, which eliminates the need for arbitration. POWERLINK communication structures designate a “managing node,” which serves as the “moderator” of the discussion. All other devices function as controlled nodes.

POWERLINK CompactCom 40-series

The Anybus CompactCom 40-series is an Ethernet hub for a variety of industrial networks. The Anybus CompactCom B40 features an Ethernet hub and NP40 chip for multiplexing and PollResponseChaining. It has a response time of less than 1 ms and is compatible with more than 20 different industrial networks. This allows for an extensive range of connectivity and opens the market to a wider range of manufacturers and application developers.

The CompactCom 40-series supports PROFINET RT Class 1 and Class 3 and includes an integrated PROFINET IRT Ethernet switch. Other features include MRP, Clock-Synchronied Operation, and Fast Start-Up, and PROFIsafe communication. The CompactCom 40-series can also be used in combination with an IXXAT Safe T100 safety module. These features make it possible to connect devices of varying types and sizes.


Using a POWERLINK TRACING TOOL to diagnose network issues can help you pinpoint the problem. It keeps count of error times, including loss of frames, CRC errors, and timeouts. The tool can also diagnose network errors at the device level. Wireshark, an open-source network tracing tool, and OmniPeak, a commercial network tracer, can show you traffic from a PC and connect to a POWERLINK device via a hub. When tracing, make sure that the LAN interface is turned off. If the network traces are highly precise, Ethernet analyzer hardware is recommended.

POWERLINK is a highly versatile, high-performance solution for industrial communications. Because it uses standard Ethernet, POWERLINK enables the use of multiple devices without the need to purchase specialized hardware. POWERLINK is widely used in diverse industries, including energy management, railway and maritime transportation, audio/video, distributed control systems, robotics, and uninterruptible power supplies. It also offers easy integration and troubleshooting features.


POWERLINK is an Industrial Real-Time Ethernet protocol based on IEEE 802.3. In a POWERLINK network, the Managing Node acts as the master, polling each controlled node cyclically. This process is called the “Start of Cyclic” (SoC). The Managing Node defines a clock pulse for synchronization and manages a cycle of data communication by successively polling each CN. The Managing Node also sends a “Start of Cycle” frame to initiate the cycle. This frame is defined in the POWERLINK data link layer.

POWERLINK uses broadcast frames to ensure that every slave receives a frame. This requires all slaves to process every frame in order to exchange information. In order to prevent this, slaves have frame filters inside their media access controllers. These filters check for slave-specific address parameters. Otherwise, the host processor in a slave would be subjected to the full frame-processing load. POWERLINK Schedule Mechanism has many advantages, including being easier to manage.
