测试技术在1996年发生了各种变化,其中最感兴趣的变化之一就是搭接到Internet进行测试。尽管网络长久以来一直是测试和测量技术的一个重要方面,但现在Internet使连接概念向前迈进了一大步。随着工作站乃至最近的PC机成为工程师的主要设计中心,Ethernet已成为仪器控制和测量的一个主要工具。几年前,Tektron-ix公司是最先开发面向企业的共享逻辑分析系统的公司之一,HP公司不久也有了类似产品。 为了给全企业网络增添远程I/O,Intelligent Instrumentation公司1996年开发出一种Ethernet数据采集系统(EDA),用以对整个工厂的数据进行实时交互存取。带EDA的远程I/O应用范围包括过程、机器或环境的监测和控制。通信是通过LAN(10Base T)或In-ternet进行的,而TCP/IP则用作开放协议,因此,几乎任何一个平台都可做为主机。
Test technology in 1996, a variety of changes, one of the most interesting changes is to catch the Internet for testing. Although the Internet has long been an important aspect of test and measurement technology, the Internet now makes the connection concept a big step forward. With workstations and even the nearest PCs becoming engineers’ major design centers, Ethernet has become a major tool for instrument control and measurement. A few years ago, Tektronix was one of the first companies to develop shared logic analytics for the enterprise, and HP soon had similar products. In order to add remote I / O to the entire enterprise network, Intelligent Instrumentation Inc. developed an Ethernet Data Acquisition System (EDA) in 1996 to allow real-time interactive access to the entire plant’s data. Remote I / O with EDA Applications include process, machine or environment monitoring and control. Communication is via LAN (10Base T) or In-ternet, while TCP / IP is used as an open protocol so that virtually any platform can be a host.
