描述

Keyence CV-200C

PLC梯形圖程序中的計(jì)數(shù)器的最高工作頻率受掃描周期的限制,一般僅有幾十Hz。在工業(yè)控制中,有時(shí)要求PLC有快速計(jì)數(shù)功能,計(jì)數(shù)脈沖可能來自旋轉(zhuǎn)編碼器、機(jī)械開關(guān)或電子開關(guān)。高速計(jì)數(shù)模塊可以對(duì)幾十kHz甚至上百Hz的脈沖計(jì)數(shù),它們大多有一個(gè)或幾個(gè)開關(guān)量輸出點(diǎn),計(jì)數(shù)器的當(dāng)前值等于或大于預(yù)置值時(shí),可通過中斷程序及時(shí)地改變開關(guān)量輸出的狀態(tài)。這一過程與PLC的掃描過程無關(guān),可以保證負(fù)載被及時(shí)驅(qū)動(dòng)。
? ? FX2N的高速計(jì)數(shù)模塊FX2N–1HC有1個(gè)高速計(jì)數(shù)器,可作單相/雙相50kHz的高速計(jì)數(shù),用外部輸入或通過PLC的程序,可使計(jì)數(shù)器復(fù)位或起動(dòng)計(jì)數(shù)過程,它可與編碼器相連。單相1輸入和單相2輸入時(shí)小于50kHz,雙相輸入時(shí)可設(shè)置為1倍頻、2倍頻和4倍頻模式,計(jì)數(shù)頻率分別為50kHz,25kHz和12.5kHz。計(jì)數(shù)值為32位有符號(hào)二進(jìn)制數(shù),或二進(jìn)制16位無符號(hào)數(shù)(O~65535)。計(jì)數(shù)方式為自動(dòng)加/減計(jì)數(shù)(1相2輸入或2相輸入時(shí))或可選擇加/減計(jì)數(shù)(1相1輸入時(shí))??捎糜布容^器實(shí)現(xiàn)設(shè)定值與計(jì)數(shù)值,一致時(shí)產(chǎn)生輸出,或用軟件比較器實(shí)現(xiàn)一致輸出(最大延遲200μs)。它有兩點(diǎn)NPN集電極開路輸出,額定值為DC5~12V,0.5A。瞬時(shí)值、比較結(jié)果和出錯(cuò)狀態(tài)均可監(jiān)視,在程序中占8個(gè)I/O點(diǎn)。

15天包退換 一年質(zhì)保 大量現(xiàn)貨? 國內(nèi)實(shí)力庫存商家


選擇深圳長欣,選擇放心,售后無憂大量現(xiàn)貨,當(dāng)天順豐發(fā)貨!
主營:本特利,英維思,伍德沃德,??怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂,ACSO,力士樂等各大品牌的DCS系統(tǒng)配件,機(jī)器人系統(tǒng)配件,大型伺服系統(tǒng)備件。

先介紹幾點(diǎn)經(jīng)驗(yàn)。
1、先通讀一遍“系統(tǒng)手冊(cè)”(不管能不能看懂,先了解個(gè)大概,以便學(xué)習(xí)編程時(shí)查找);
2、由位控邏輯入手,逐漸增加定時(shí)、計(jì)數(shù)等條件,把或、與、非關(guān)系理順;
3、進(jìn)而練習(xí)整數(shù)運(yùn)算、實(shí)數(shù)運(yùn)算、類型轉(zhuǎn)換;
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解(最好是有個(gè)物理回路驗(yàn)證,比如變頻器+電機(jī)+測(cè)速傳感器);
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制(盡量避免跳轉(zhuǎn),非跳不可時(shí)也是跳的越近越好);
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機(jī)器人配件DSQC系列和Motorola MVME系列,GE 卡件 模塊 驅(qū)動(dòng)器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌,由于PLC的基本框架大同小異,學(xué)會(huì)一種至于其它的學(xué)習(xí)起來也就簡單了。
