VT-VPCD-1-1X/V0/1-0-1

可編程控制器（ProgrammableController，簡稱PC）是一種數(shù)字運(yùn)算操作的電子設(shè)備。它使用了可編程序的存儲器，用來在其內(nèi)部存儲執(zhí)行邏輯運(yùn)算、順序控制、定時、計數(shù)和算術(shù)運(yùn)算等操作指令，通過數(shù)字或模擬輸入/輸出組件控制各種類型的機(jī)械或生產(chǎn)過程。PC具有功能齊全、應(yīng)用靈活、操作維修容易方便和穩(wěn)定可靠等特點(diǎn)，因此廣泛用于工業(yè)現(xiàn)場控制。其典型應(yīng)用方案是：采用PC作為下位機(jī)實現(xiàn)過程的自動控制，以微機(jī)為上位機(jī)，完成工業(yè)流程和工藝參數(shù)的顯示以及控制參數(shù)的修改等功能。但是在一些危險和惡劣環(huán)境下，需要用微機(jī)遠(yuǎn)程控制PC系統(tǒng)的運(yùn)行和停止。本文結(jié)合作者所開發(fā)的危險環(huán)境下控制系統(tǒng)，以三菱A2A可編程控制器為例介紹VB遠(yuǎn)程控制三菱A系列可編程控制器的運(yùn)行，并給出系統(tǒng)實現(xiàn)方法與示例程序。

PLC作為一種高性能的控制裝置，在分布式系統(tǒng)中得到了越來越廣泛的應(yīng)用。在這種控制系統(tǒng)中，PLC可以多種方式，如直接采用現(xiàn)有的組態(tài)監(jiān)控軟件與上位機(jī)通信，但針對小規(guī)模的控制系統(tǒng)，找到一種高性能價格比的通信方法，具有積極的實際意義。本文就日本三菱公司生產(chǎn)的FX2可編程控制器與監(jiān)控中心通信方式的實現(xiàn)，從軟、硬件兩個方面來說明這個問題。隨著GSM移動通信網(wǎng)絡(luò)的迅速發(fā)展和用戶的日益擴(kuò)大，新技術(shù)和新業(yè)務(wù)的開發(fā)和應(yīng)用就已提到十分重要的位置。短消息服務(wù)業(yè)務(wù)作為ＧＳＭ網(wǎng)絡(luò)的一種基本業(yè)務(wù)，已得到越來越多的系統(tǒng)運(yùn)營商和系統(tǒng)開發(fā)商的重視，基于這種業(yè)務(wù)的各種應(yīng)用也蓬勃發(fā)展起來。

以往，在無人值守的現(xiàn)場出現(xiàn)問題后，維修人員不可能訊速趕到現(xiàn)場排除故障，造成許多不必要的損失，所以作者設(shè)計了該采集與監(jiān)控系統(tǒng)，將告警信息通過手機(jī)短消息的方式，發(fā)送到集中監(jiān)控中心，從而實現(xiàn)了遠(yuǎn)程遙控、遙測、遙調(diào)、遙訊。
