The BroadR-Reach Click by Mikro Elektronika brings the industry-grade communication standard to the mikroBUS™, which is suitable for use in an Ethernet-based open network. The click board utilizes the BCM54811 Transceiver from Broadcom Limited that provides the hardware PHY layer for the Ethernet network.
The W3150A+ chip from WizNet, a hardware LSI protocol stack, presents an easy and low-cost solution for high-speed Internet connectivity for digital devices by enabling easy installation of the TCP/IP stack in the hardware.
The BroadR-Reach® point-to-point Ethernet PHY technology was developed by Broadcom Limited. The BroadR-Reach® technology represents a robust Ethernet physical layer interface, designed for use in noisy environments and harsh conditions, such as in industrial or automotive networking applications.
The technology enables various systems to concurrently access information over the unshielded single twisted pair cable, reducing connectivity costs and cabling weight. As such, it offers a comprehensive alternative to older and limited standards used so far and supports increased data rates over existing cable networks.

The following is part of A Comprehensible Guide to Industrial Ethernet by Wilfried Voss.Any solution attempting to achieve true determinacy and real-time control based on Ethernet TCP/IP requires the elimination of the CSMA/CD, IP, and UDP components, because their combined characteristics contribute to unpredictable cycle times and additional jitter.CSMA/CD can be easily eliminated through the use [...]
The following is part of A Comprehensible Guide to Industrial Ethernet by Wilfried Voss.The demand for Ethernet as a real-time communication network has increased continuously in the past due to the benefits of employing a single network technology throughout the manufacturing facility, from office to plant floor.However, the unpredictable nature of Ethernet TCP/IP’s timing (which will [...]
The following is part of A Comprehensible Guide to Industrial Ethernet by Wilfried Voss.There are, in fact, only few limitations to Ethernet as a standard networking technology, and those that exist can be rectified easily.There are practical limits to the size (physical network length, number of devices) of a complete Ethernet network that shares a single [...]
The following is part of A Comprehensible Guide to Industrial Ethernet by Wilfried Voss.The following chapter explains, in brief, the functionality of Ethernet, CSMA/CD (Carrier-sense multiple access with collision detection), TCP/IP (Transmission Control Protocol / Internet Protocol), and UDP (User Datagram Protocol).EthernetEthernet represents the physical protocol layer, i.e., it covers the physical medium (e.g., cables, RJ45 ports, LAN cards, [...]
The following is part of A Comprehensible Guide to Industrial Ethernet by Wilfried Voss.Note: This chapter can only provide a rudimentary overview of the underlying Ethernet technology. There are already a significant number of works on TCP/IP available (see also the “References” appendix) that explain the topic in great detail.Nevertheless, the information in this chapter is [...]
The following is part of A Comprehensible Guide to Industrial Ethernet by Wilfried Voss.The TCP/IP layer model follows the OSI 7-Layer Reference Model to a certain degree as demonstrated in the image documenting the Ethernet TCP/IP protocol layers. The similarities to the OSI model are apparent.However, they do have their subtle differences. After all, OSI is [...]
The following is part of A Comprehensible Guide to Industrial Ethernet by Wilfried Voss.As the term Ethernet TCP/IP (Transmission Control Protocol / Internet Protocol) indicates, Ethernet TCP/IP is not a single protocol. It comprises of a full suite of protocols based on the two original protocols TCP and IP. In other words, Ethernet TCP/IP is a layered protocol, where each layer [...]
The following is part of A Comprehensible Guide to Industrial Ethernet by Wilfried Voss. The OSI Reference Model is at the heart of serial networking technologies, including Industrial Ethernet. The understanding of the model is mandatory, not only when it comes to understanding Ethernet TCP/IP, the underlying technology of Industrial Ethernet; it also serves as a model explaining how the different [...]
