Description: 本文详细介绍了工控机与PLC(可编程控制器...以三菱PLC为例),通过串口进行通讯的方法与步骤.
PLC大量运用于设备控制,具有稳定可靠,容易编程的特点,往往用于设备的底层控制.
而工控机具有友好的界面,容易被操作者所接受.因此,将工控机与PLC结合,实现设备的智能化控制,被广泛采用.
正是因为以上用途,提出了工控机与PLC通讯的问题,本文说明清晰,贴近实用.

Description: vb与三菱plc 通讯程序，基础知识，未曾清贫难成人，不经打击老天真，从来英雄出炼狱，自古富贵入凡尘，醉生梦死谁成器，托马长枪定乾坤。(VB (Visual Basic) is Microsoft Corporation promotes based on the Basic language visualization
programming environment, but by its simple easy to study, the function formidable time the general computer
amateur's favor, many application software all use VB to take the software development platform. In uses VB to
develop the application software in the process, how uses the database and carries on the management for the
database is all exploiter issue of concern.VB was the database programming has provided very many tools and the
way, actually selected what method to carry on the database the visit to rely on user's different demand, the
following on makes a simple analysis to the VB database programming way.)
