電力用戶曾使用PLC，用以實(shí)時記錄用戶用電情況，以實(shí)現(xiàn)不同用電時間、不同計價的收費(fèi)辦法，鼓勵用戶在用電低谷時多用電，達(dá)到合理用電與節(jié)約用電的目的。
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(shí)，*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(shí)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。
