以太网是一颗正在升起的新星。然而对它的物理要求应紧密关注。找出这些要求是什么以及如何满足这些要求,本文作者提出了他们的建议。十五多年以前,自从以太网被IEEE采用作为开放式标准后,它在办公室领域里真正是无所不在。与此同时,制造加工业对网络器件的要求也与日俱增。这一趋势主要是由于希望降低安装成本,加快试运行进度以及主要由可编程控制器(PLC)生产商开发的专有网络等因素所驱动。当客户迫切要求多生产商提供的一流自动化部件能相互连接时,促使90年代“开放式”网络的萌芽。与办公室领域
Ethernet is a rising star. However, its physical requirements should be closely watched. Find out what these requirements are and how to meet these requirements, the author of this article made their suggestion. More than fifteen years ago, Ethernet was truly ubiquitous in the office space since it was adopted by the IEEE as an open standard. In the meantime, the requirements of the manufacturing and processing industry on network devices are also increasing. This trend is driven primarily by the desire to lower installation costs, speed up trial runs, and proprietary networks primarily developed by programmable controller (PLC) manufacturers. When customers are pressing for the connection of first-class automation components provided by multiple manufacturers to one another, they are the seeds of the ’open’ network of the 1990s.
