急......请各位哥哥姐姐帮我翻译一下毕业摘要

目前PLC 己成为工业控制的标准设备,是自动控制系统的三大技术支柱之一, 在自动控制系统的应用中,可编程序控制器占据着举足轻重的地位。
本次设计的内容是FC系列可编程控制器模拟运行软件的开发，是在Windows操作系统环境下运用Visual Basic语言来进行模拟仿真的。在熟练掌握VB语言的编程及特点和FC系列可编程控制器的操作与编程后，用VB语言对PLC程序指令进行解释，并结合逻辑判断以及控制功能和在VB的窗体中显示出与PLC运行相一致的过程和结果，使抽象的程序一目了然地展现与眼前。
本论文大致可分为四个部分：第一部分主要对VB程序设计的相关知识做了介绍；第二部分介绍了PLC的基本组成和工作原理；第三部分主要是对程序的解释和控制功能的分析；最后一部分是可编程控制器的实例模拟。
本论文所设计软件可用于PLC的模拟运行与学习，经进一步完善和扩充功能也可作为基于计算机平台控制技术的基础。

Answer 1

At present PLC oneself becomes the industrial control the standard equipment, is automatic control system's one of three big technology props, in automatic control system's application, the programmable controller is occupying the pivotal status. the this design's content is the FC series programmable controller simulation run software's development, is language carries on the analog simulation under the Windows operating system environment using Visual the Basic. After has a good command of the VB language skilled the programming and the characteristic and the FC series programmable controller's operation and the programming, carries on the explanation with the VB language to the PLC program directive, and unifies the logical judgement as well as the control function and demonstrated in the VB window with the PLC movement consistent process and the result, causes the abstract procedure clear development and at present. the present paper may divide into four parts approximately: The first part mainly has made the introduction to the VB programming's related knowledge; The second part introduced the PLC basic composition and the principle of work; The third part is mainly to the procedure explanation and the control function analysis; Last part is the programmable controller's example simulation. the present paper designs the software to be possible to use in PLC the simulation run and studies, after further consummates and the extended function may also take based on the computer platform control technology foundation.

Answer 2

The current PLC has become the standard industrial control equipment, automatic control system is one of the pillars of the three major technology, automatic control system in the application, the PLC occupy a pivotal position.
The design of the series is FC PLC simulation software development operation, is in the Windows operating system environment using Visual Basic language to conduct the simulation. VB in mastering the programming language and characteristics and FC series PLC after the operation and programming, the PLC by VB language to explain procedures directive, combined with logic and judgement, and control functions in the form shown in VB PLC to run in line with the process and results of the abstract process to demonstrate clear and immediate.
The papers generally

Answer 3

The current PLC has become the standard industrial control equipment, automatic control system is one of the pillars of the three major technology, automatic control system in the application, the PLC occupy a pivotal position.
The design of the series is FC PLC simulation software development operation, is in the Windows operating system environment using Visual Basic language to conduct the simulation. VB in mastering the programming language and characteristics and FC series PLC after the operation and programming, the PLC by VB language to explain procedures directive, combined with logic and judgement, and control functions in the form shown in VB PLC to run in line with the process and results of the abstract process to demonstrate clear and immediate.
This paper can be broadly divided into four parts: the first part of the main VB program designed to introduce the relevant knowledge to do the second part of the PLC on the basic composition and working principle is the third part of the process of interpretation and control functions Analysis of the last part of the PLC examples of simulation.
This paper can be used to design software by the PLC and run the simulation study, by further improving and expanding the functions also as a platform for computer-based control technology.
