6ES7902-2AG00-0AA0 20mA/TTY電纜 調(diào)試方法有兩種：

①模擬方法：按設(shè)計(jì)做一塊調(diào)試板，以鈕子開關(guān)模擬輸入節(jié)點(diǎn)，以小型繼電器模擬生產(chǎn)工藝設(shè)備的繼電器與接觸器，其輔助接點(diǎn)模擬設(shè)備運(yùn)行時(shí)的返回信號(hào)節(jié)點(diǎn)。其優(yōu)點(diǎn)是具有模擬的真實(shí)性，可以反映出開關(guān)速度差異很大的現(xiàn)場機(jī)械觸點(diǎn)和PLC內(nèi)的電子觸點(diǎn)相互連接時(shí)，是否會(huì)發(fā)生邏輯誤動(dòng)作。其缺點(diǎn)是需要增加調(diào)試費(fèi)用和部分調(diào)試工作量。

②強(qiáng)置方法：利用PLC強(qiáng)置功能，對(duì)程序中涉及現(xiàn)場的機(jī)械觸點(diǎn)(開關(guān))，以強(qiáng)置的方法使其“通”、“斷”，迫使程序運(yùn)行。其優(yōu)點(diǎn)是調(diào)試工作量小，簡便，不需另外增加費(fèi)用。缺點(diǎn)是邏輯驗(yàn)證不，人工強(qiáng)置模擬現(xiàn)場節(jié)點(diǎn)“通”、“斷”，會(huì)造成程序運(yùn)行不能連續(xù)，只能分段進(jìn)行。

根據(jù)我們現(xiàn)場調(diào)試的經(jīng)驗(yàn)，對(duì)部分重要的現(xiàn)場節(jié)點(diǎn)采取模擬方式，其余的采用強(qiáng)置方式，取二者之長互補(bǔ)。邏輯驗(yàn)證階段要強(qiáng)調(diào)逐日填寫調(diào)試工作日志，內(nèi)容包括調(diào)試人員、時(shí)間、調(diào)試內(nèi)容、修改記錄、故障及處理、交接驗(yàn)收簽字，以建立調(diào)試工作責(zé)任制，留下調(diào)試的第一手資料。對(duì)于設(shè)計(jì)程序的修改部分，應(yīng)在設(shè)計(jì)圖上注明，及時(shí)征求設(shè)計(jì)者的意見，力求準(zhǔn)確體現(xiàn)設(shè)計(jì)要求。
