3.5用于信號監(jiān)控

PLC自檢信號很多，內(nèi)部器件也很多，多數(shù)使用者未充分發(fā)揮其作用。

其實，完全可利用它進(jìn)行PLC自身工作的監(jiān)控，或?qū)刂茖ο筮M(jìn)行監(jiān)控。

這里介紹一種用PLC定時器作看門狗，對控制對象工作情況進(jìn)行監(jiān)控的思路。

如用PLC控制某運(yùn)動部件動作，看施加控制后動作進(jìn)行了沒有，可用看門狗辦法實現(xiàn)監(jiān)控。具體作法是在施加控制的同時，令看門狗定時器計時。如在規(guī)定的時間內(nèi)動作完成，即定時器未超過警戒值的情況下，已收到動作完成信號，則說明控制對象工作正常，無需報警。
