流程控制指令，用以控制程序運行流程。PLC的用戶程序一般是從零地址的指令開始執(zhí)行，按順序推進。但遇到流程控制指令也可作相應改變。流程控制指令也較多，運用得好，可使程序簡練，并便于調(diào)試與閱讀。 

   狀態(tài)監(jiān)控指令，用以監(jiān)視及記錄PLC及其控制系統(tǒng)的工作狀態(tài)，對提高PLC控制系統(tǒng)的工作可靠性大有幫助。 

   當然，并不是所有的PLC都有上述那么多類的指令，也不是有的PLC僅有上述幾類指令。以上只是指出幾個例子，說明要從哪幾個方面了解PLC指令，從中也可大致看出指令的多少及功能將怎樣影響PLC的性能。 現(xiàn)貨，現(xiàn)貨，降降降，火火火，火火火……
