檢查I/O，俗稱“打點(diǎn)”。檢查I/O的方法很多，但是一定要根據(jù)說(shuō)明書提供的地址依次進(jìn)行檢查，在絕對(duì)安全的情況下來(lái)檢查。
在檢查輸入點(diǎn)時(shí)，一般輸入信號(hào)無(wú)非是各種傳感器，如電容、電感、光電、壓阻、超聲波、磁感式和行程開(kāi)關(guān)等傳感器。檢查這些元件比較簡(jiǎn)單，根據(jù)元件說(shuō)明將工件放在工位上，或是移動(dòng)執(zhí)行機(jī)構(gòu)檢查傳感器是否有信號(hào)即可。當(dāng)然，不同的設(shè)備檢測(cè)的方式可能不同，這要看具體情況而定了。
但是在檢查輸出信號(hào)時(shí)就要格外小心了。如果是電驅(qū)動(dòng)產(chǎn)品，必須在安全情況下，尤其是保證設(shè)備不會(huì)發(fā)生撞擊前提下，讓執(zhí)行機(jī)構(gòu)的驅(qū)動(dòng)器得電，檢查執(zhí)行機(jī)構(gòu)是否能夠運(yùn)動(dòng)。如果是液壓或氣動(dòng)執(zhí)行機(jī)構(gòu)，同樣在安全情況下手動(dòng)使換向閥得電，從而控制執(zhí)行機(jī)構(gòu)。在檢查輸出信號(hào)時(shí)，不論執(zhí)行機(jī)構(gòu)的驅(qū)動(dòng)方式是什么，一定要根據(jù)元件說(shuō)明書，首先要保證設(shè)備和人身安全，要注意并不是所有設(shè)備的執(zhí)行機(jī)構(gòu)都可以通電測(cè)試的，所以有時(shí)個(gè)別的輸出信號(hào)可能無(wú)法手動(dòng)測(cè)試。無(wú)論是輸入還是輸出裝置，當(dāng)傳感器有信號(hào)或執(zhí)行機(jī)構(gòu)的驅(qū)動(dòng)裝置得電后，必須同時(shí)檢查PLC上的I/O模塊指示燈是否也點(diǎn)亮。很多設(shè)備中，輸入輸出信號(hào)是通過(guò)接線端子與PLC連接，有時(shí)接線端子的指示燈有信號(hào)，但不能保證由于連接導(dǎo)線內(nèi)部斷路，而PLC上相應(yīng)的地址沒(méi)有信號(hào)接通。這一點(diǎn)要特別注意。
在測(cè)量輸入輸出信號(hào)后，要同時(shí)將測(cè)量的地址記錄下來(lái)，保證信號(hào)地址和說(shuō)明書中一致。如有不同，再次測(cè)量設(shè)備地址，多次測(cè)量仍然不一致，先聯(lián)系設(shè)備廠家，因?yàn)榇藭r(shí)不能保證廠家提供的地址沒(méi)有錯(cuò)誤。
