描述

特殊標志位為用戶提供一些特殊的控制功能及系統(tǒng)信息，用戶對操作的一些特殊要求也要通過SM通知系統(tǒng)。特殊標志位分為只讀區(qū)和可讀可寫區(qū)兩部分。

只讀區(qū)特殊標志位，用戶只能使用其觸點，如：

SM0.0RUN監(jiān)控，PLC在RUN狀態(tài)時，SM0.0總為1。

SM0.1初始化脈沖，PLC由STOP轉為RUN時，SM0.1接通一個掃描周期。

SM0.2當RAM中保存的數(shù)據(jù)丟失時，SM0.2接通一個掃描周期。

SM0.3PLC上電進入RUN時，SM0.3接通一個掃描周期。

SM0.4該位提供了一個周期為1min，占空比為0.5的時鐘。

SM0.5該位提供了一個周期為1S，占空比為0.5的時鐘。

SM0.6該位為掃描時鐘，本次掃描置1，下次掃描置0，交替循環(huán)?？勺鳛閽呙栌嫈?shù)器的輸入。

SM0.7該位指示CPU工作方式開關的位置，0=TERM，1=RUN。通常用來在RUN狀態(tài)下啟動自由口通信方式。

可讀可寫特殊標志位用于特殊控制功能，如用于自由口設置的SMB30，用于定時中斷時間設置的SMB34/SMB35，用于高速計數(shù)器設置的SMB36～SMB62，用于脈沖輸出和脈沖調制的SMB66～SMB85等。
