問(wèn)：我用的是EM222輸出模塊，我想輸出220V到時(shí)中間繼電器，Q0，1，2，3都用過(guò)了，現(xiàn)在我想用Q4，5，6，7輸出，輸出的時(shí)候燈是亮的，但就是沒(méi)有電壓，沒(méi)法用呀，不知道是怎么回事，不會(huì)下面4個(gè)點(diǎn)是電流輸出吧

答：em222有2種，繼電器輸出型和晶體管輸出型。據(jù)說(shuō)還將推出雙向可控硅型。

繼電器輸出型需要提供繼電器線圈的驅(qū)動(dòng)電源，即 L+和 M，是DC24v的，試驗(yàn)的話，可以由cpu的L+和M 驅(qū)動(dòng)。

從描述看，您沒(méi)有提供這個(gè)電源。所以指示燈亮（內(nèi)部5V邏輯），但觸點(diǎn)沒(méi)有吸合。

補(bǔ)充：

輸出點(diǎn)分組的

1L  qx.0 .1 .2 .3

2L  qx.4 .5 .6 .7

您需要將220v的火線接到2L上， .4接負(fù)載，而負(fù)載另一端接220V的N線

問(wèn)：cpu是314，只有一個(gè)MPI口，有一個(gè)343-1以太網(wǎng)模塊，觸摸屏是MP277，上位機(jī)2臺(tái)。

打算幾種組網(wǎng)方式：

1、以太網(wǎng)模塊接交換機(jī)，mp277和所有的上位機(jī)都接到交換機(jī)上

2、以太網(wǎng)接交換機(jī)，工控機(jī)接交換機(jī)上。MP277和PLC通過(guò)MPI通訊

想請(qǐng)教一下，以上兩種方案都可以實(shí)現(xiàn)吧，哪種好一些呢，哪種方式觸摸屏通訊可靠快速?。?！

答：其實(shí)兩種方法都非常好，另外就是考慮那種方案需要的線要長(zhǎng)一些的問(wèn)題了，不過(guò)建議mp277使用以太網(wǎng)進(jìn)行通訊，因?yàn)榫W(wǎng)線哪里都可以買到而且還非常方便，即插即用，便于維護(hù)。

問(wèn)：我們STEP7編程軟件庫(kù)里有一些如FC33 FC40 FC105，等等，但是我們使用時(shí)是不是要注意先看看庫(kù)里有沒(méi)有這個(gè)號(hào)，如果有，證明這個(gè)塊號(hào)如33 40 105不可以使用，如果這樣子的話，我覺(jué)得創(chuàng)建功能塊那不是很麻煩嗎。萬(wàn)一沖突了就弄不清楚，是不是可以用同樣的編號(hào)也可以作普通的功能FC使用？？

答：不需要。

1、庫(kù)中的FC有特殊功能，調(diào)用特殊功能的FC要從庫(kù)里調(diào)用。

2、直接編號(hào)的是普通的的FC,沒(méi)有特殊功能。

3、如果調(diào)用庫(kù)中的FC時(shí)出現(xiàn)編號(hào)相同是可重命名用，特殊功能不消失。

問(wèn)：請(qǐng)問(wèn)EM231模塊至熱電偶傳感器距離是不是有長(zhǎng)度限制，是多少，如果距離超過(guò)的話，有什么好的解決辦法呢？

答：個(gè)人認(rèn)為回路阻抗和干擾情況是決定傳輸距離的決定因素，理論上到變送器的距離為100米，是在回路阻抗小于100歐，干擾不嚴(yán)重的場(chǎng)合。

熱電偶距離無(wú)法滿足要求的話，先增加變送器，4~20mA信號(hào)足以滿足你的距離要求了，再不行就將200與現(xiàn)場(chǎng)靠近些

問(wèn)：SM322的燈為什么不亮?。繌?qiáng)制它也沒(méi)反應(yīng)，換一個(gè)322還是一樣。請(qǐng)各位高手幫幫忙??！

答：“SM322的燈為什么不亮啊？強(qiáng)制它也沒(méi)反應(yīng)，換一個(gè)322還是一樣。”？

.檢查模板與安裝導(dǎo)軌，前連接器與模板安裝是否安裝牢固。

.模板的電源是否連接正確？

.檢查CPU的狀態(tài)是否為RUN.?

.檢查地址與STEP7中的硬件組態(tài)中所設(shè)置的是否一致？
