描述

狀態(tài)繼電器（S）是PLC內(nèi)部“軟繼電器”的一種，它和輸入繼電器（X）和輸出繼電器（Y）一樣，有無(wú)數(shù)對(duì)常開(kāi)觸點(diǎn)和常閉觸點(diǎn)，如不作步進(jìn)狀態(tài)軟元件，可作一般的輔助繼電器（M）使用。FX系列內(nèi)部共有狀態(tài)繼電器1000個(gè)，S0~S9主要應(yīng)用在狀態(tài)轉(zhuǎn)移圖（SFC）的初始狀態(tài)，S10~S19主要應(yīng)用在狀態(tài)轉(zhuǎn)移圖（SFC）的狀態(tài)回零，S20~S499主要應(yīng)用在狀態(tài)轉(zhuǎn)移圖（SFC）的中間狀態(tài)，S500~S899與S900~S999分別用在停電保持和信號(hào)報(bào)警。

在圖1所示的工序步進(jìn)控制中如果啟動(dòng)信號(hào)X000為ON。則狀態(tài)S20置位ON，下降用的電磁閥Y000動(dòng)作。若下限限位開(kāi)關(guān)X001為ON，則狀態(tài)S21置位ON，夾緊用的電磁閥Y001動(dòng)作。如果夾緊動(dòng)作的限位開(kāi)關(guān)X002為ON，則狀態(tài)S22置位ON。隨著動(dòng)作的轉(zhuǎn)移，狀態(tài)自動(dòng)返回原狀態(tài)。普通用途狀態(tài)在電源斷開(kāi)后，都變?yōu)镺FF狀態(tài)；而停電保持用的狀態(tài)，可記憶停電前一刻的ON或OFF狀態(tài)，所以也能夠從中途工序開(kāi)始運(yùn)行。
