一般認(rèn)為輸入點(diǎn)數(shù)是按系統(tǒng)輸入信號(hào)的數(shù)量來(lái)確定的。但在實(shí)際應(yīng)用中,通過(guò)以下措施可達(dá)到節(jié)省PLC輸入點(diǎn)數(shù)的目的,下面以FX1N系列PLC來(lái)介紹。
(1)分組輸入 如圖1所示,系統(tǒng)有“手動(dòng)"和“自動(dòng)"兩種工作方式。用X000來(lái)識(shí)別使用“自動(dòng)"還是“手動(dòng)"操作信號(hào),“手動(dòng)"時(shí)的輸入信號(hào)為SB0~SB3,“自動(dòng)"時(shí)的輸入信號(hào)為S0~S3,如果按正常的設(shè)計(jì)思路,那么需要X000~X007一共8個(gè)輸入點(diǎn),若按圖1的方法來(lái)設(shè)計(jì),則只需X001~X004一共4個(gè)輸入點(diǎn)。圖中的二極管用來(lái)切斷寄生電路。如果圖中沒(méi)有二極管,系統(tǒng)處于自動(dòng)狀態(tài),SB0、SB1、S0閉合S1斷開(kāi),這時(shí)電流從COM端子流出,經(jīng)SB0、SB1、S0形成寄生回路流入X000端子,使輸入位X002錯(cuò)誤地變?yōu)?/span>ON。各開(kāi)關(guān)串聯(lián)了二極管后,切斷了寄生回路,避免了錯(cuò)誤的產(chǎn)生。但使用該方法應(yīng)考慮輸入信號(hào)強(qiáng)弱。
