描述

1756-TBCH

?對(duì)于一個(gè)S7-1200CPU的web服務(wù)器有30個(gè)連接資源用于web服務(wù)連接,對(duì)于S7-1500CPU有138個(gè)web服務(wù)連接。一個(gè)瀏覽器頁(yè)面所占用的連接數(shù)根據(jù)瀏覽器的種類和版本不同而不同。
? ? 如果以管理員身份登陸到服務(wù)器上,然后在沒有注銷的情況下直接關(guān)閉這個(gè)應(yīng)用,那么連接仍然是被保留的。如果對(duì)S7-1200CPU重復(fù)7到8次這個(gè)過(guò)程,或者對(duì)S7-1500CPU重復(fù)30到40次,那么就會(huì)占用到最大的連接數(shù)量,不能在進(jìn)行更多的通信。
? ? 此時(shí)S7-1200CPU會(huì)給出消息,指出登陸名和密碼是無(wú)效的。而S7-1500CPU不會(huì)給出任何消息,以至于會(huì)認(rèn)為是登陸名和密碼是錯(cuò)誤的。
? ? 我們推薦重新啟動(dòng)計(jì)算機(jī)來(lái)作為補(bǔ)救措施?;蛘撸?dāng)這個(gè)連接在30分鐘以內(nèi)沒有再次使用就會(huì)自動(dòng)釋放出來(lái),那么就可以再次登陸了。

選擇深圳長(zhǎng)欣,選擇放心,售后無(wú)憂大量現(xiàn)貨,當(dāng)天順豐發(fā)貨!
主營(yíng):本特利,英維思,伍德沃德,福克斯波羅、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(lái)也就簡(jiǎn)單了。
