【正文】 基于VB的臺(tái)達(dá)PLC與監(jiān)控計(jì)算機(jī)的串行通信實(shí)現(xiàn)中達(dá)電通股份有限公司 中達(dá)電通上海機(jī)電PLC產(chǎn)品處 王乃全 Implementation of Serial Communication Between Monitoring Computer and Delta PLC Based on Visual BasicWang Naiquan 摘要：PLC直接與現(xiàn)場控制層的檢測儀器儀表設(shè)備連接，是底層控制網(wǎng)絡(luò)的組成部分，是工廠自動(dòng)化系統(tǒng)的基石，因此實(shí)現(xiàn)與監(jiān)控層計(jì)算機(jī)的通信對(duì)系統(tǒng)的優(yōu)化運(yùn)行有重要意義。文章基于VB討論臺(tái)達(dá)DVP PLC與監(jiān)控計(jì)算機(jī)的通信問題。關(guān)鍵詞：VB 通信協(xié)議 可編程控制器Abstract: The PLC is a posing part of Infranet, it links to the measuring instrument and device in field control layer directly, and is the footstone of factory automation system. Therefore it is very important to realize the munication between PLC and monitoring layer puter for optimization of syste running. The paper discussed the related munication problems between Delta DVP PLC and monitoring puter based on Visual Basic. Key Words: Visual Basic Communication protocal Programable logic controller[中圖分類號(hào)] TP273 [文獻(xiàn)標(biāo)識(shí)碼] B 文章編號(hào)1 引 言 現(xiàn)場設(shè)備層中的設(shè)備種類繁多,有傳感器、啟動(dòng)器、驅(qū)動(dòng)器、I/O部件、變送器、閥門等等,當(dāng)然也包括現(xiàn)場檢測儀器儀表設(shè)備。PLC是現(xiàn)場設(shè)備控制層不可缺少的部分，已經(jīng)非常普及，如何簡便地實(shí)現(xiàn)與PLC的交互已經(jīng)成為眾多廠商新的競爭
