描述
FX系列PLC有基本邏輯指令20或27條、步進(jìn)指令2條、功能指令100多條(不同系列有所不同)。本節(jié)以FX2N為例,介紹其基本邏輯指令和步進(jìn)指令及其應(yīng)用。
FX2N的共有27條基本邏輯指令,其中包含了有些子系列PLC的20條基本邏輯指令。
觸點(diǎn)并聯(lián)指令(OR/ORI/ORP/ORF)
(1)OR(或指令)用于單個(gè)常開觸點(diǎn)的并聯(lián),實(shí)現(xiàn)邏輯“或”運(yùn)算。
(2)ORI(或非指令)用于單個(gè)常閉觸點(diǎn)的并聯(lián),實(shí)現(xiàn)邏輯“或非”運(yùn)算。
(3)ORP上升沿檢測(cè)并聯(lián)連接指令。
(4)ORF下降沿檢測(cè)并聯(lián)連接指令。
