三菱FX2N PLC步進(jìn)指令簡介,
|
在FX2N系列PLC中只有兩條步進(jìn)指令：STL（步進(jìn)開始指令）和RET（步進(jìn)結(jié)束指令）。
STL和RET指令必須和狀態(tài)繼電器S配合使用才具有步進(jìn)功能。STL也稱為步進(jìn)觸點(diǎn)指令（占1步），STL的梯形圖符號用 表示，稱為STL觸點(diǎn)，它沒有動斷觸點(diǎn)。STL S20 和STL S21都是STL觸點(diǎn)。在梯形圖中，STL觸點(diǎn)與母線相連，使用STL指令后，母線移至觸點(diǎn)右側(cè)，其后需用LD、LDI、OUT等指令，直至出現(xiàn)下一條STL指令或出現(xiàn)RET指令。STL指令使新狀態(tài)繼電器置位，而前一狀態(tài)繼電器自動復(fù)位，其觸點(diǎn)斷開。圖10-1表明了順序功能圖、梯形圖、語句表三者之間的嚴(yán)格對應(yīng)關(guān)系。步進(jìn)結(jié)束指令RET也稱為步進(jìn)返回指令，梯形圖符號用 表示。在一系列STL指令之后必須使用RET指令，以表示步進(jìn)指令功能結(jié)束，母線恢復(fù)至原位。
