In recent years, the industry has been undergoing a significant change in the way it communicates - from hierarchical networks characterized by a diversity of systems and standards, we are moving to a more centralized and unified approach. This new trend, based on Single-Pair Ethernet (SPE) technology, offers a solution to some of the long-standing problems associated with the complexity of traditional networks. In this article, we take a look at how this innovative technology is revolutionizing the industrial communications environment, promising a more efficient, scalable and integrated future. Keep reading to learn how single-pair Ethernet sensors can benefit your business!
Traditional industrial networks are characterized by a hierarchical structure, with multiple levels of communication and a variety of bus systems. Different parts of the factory have their own hardware architectures and buses dedicated to specific applications. Such an architecture presents various problems including the complexity and variety of communication protocols and standards used (e.g. Profibus, Ethercat and CAN), limited scalability and performance.
The advent of Single Pair Ethernet (SPE) technology has sparked a revolution in industrial networking. SPE offers a centralized, Ethernet-based solution that eliminates the problems of traditional architectures.
Pyramid of automation
The development of Single Pair Ethernet (SPE) technology began in 2011 with the publication of the BroadR-Reach communications standard for the automotive industry. Here are the main goals of SPE's creation and its features:
Specification: untwisted two-wire cable, capable of 100 Mbps data transmission (high Ethernet speed on just 2 wires), which provided weight savings and ease of connection.
SPE quickly spread and found wide application in various industrial sectors.
Single Pair Ethernet (SPE) is a cutting-edge approach in the field of network infrastructure that promises significant changes in the way data is transmitted, especially in the context of the Industrial Internet of Things (IIoT). This technology opens up the possibility of directly transmitting sensor data using just two wires of Ethernet cable, enabling a unified and consistent communications architecture extending from the sensor all the way to the cloud.
SPE addresses the needs of today's industry by enabling a consistent communications infrastructure across a broad spectrum of applications where data is critical. The concept is based on the ability to extend Ethernet connectivity to the lowest level in the communications hierarchy - that is, to sensors where broadband connections were previously not possible or practical. SPE thus offers a solution for efficient data transfer, even for compact devices requiring long range, which is crucial for the development of IIoT and modern industrial communications.
Single Pair Ethernet technology opens up new possibilities in many industrial sectors. Here are a few examples of its applications:
In addition to the examples mentioned above, SPE can also be used in other industrial sectors, such as:
Problem: Managing temperature and humidity in a production hall is essential for the quality of manufactured products, the comfort of employees, and the proper functioning of machines. Traditional monitoring systems can be complex and costly to maintain.
