英语翻译
Relay users that have a machine or process operating with some or all of the following characteristics would be candidates for programmable controller-based control:repetitive operations,time-driven operations,event-driven operations,high speed control,and requirements for data acquisition/manipulation.A few application examples with these characteristics include conveyors,packaging operations and vending machines.
Choosing the Right Programmable Controller
After a user justifies the conversion from relays to programmable controllers,the next step is to Define the Control Application.Defining the control application to get the number of field devices is the first of four procedures in choosing the programmable controller specification.This procedure involves identifying and describing each of the functions within the process.For example,

继电器的用户,这里有一种机器或过程的操作与一些或全部的特征主要是候选人controller-based控制:可编程操作、time-driven重复操作,事件驱动的业务,高速度控制,和要求数据采集/操作.一些应用实例以这些特质包括输送线、包装操作和自动售货机.
选择正确的可编程控制器
在一个用户为转换成可编程控制器继电器,下一步是定义控制技术的应用.定义控制技术的应用到现场设备的数量是第四个程序,在选择可编程序控制器的规格.这个过程包括识别功能,详细介绍每一个在这个过程.例如
