PLC也可與計(jì)算機(jī)通訊,由計(jì)算機(jī)把DM區(qū)的數(shù)據(jù)讀出,并由計(jì)算機(jī)再對(duì)這些數(shù)據(jù)作處理。這時(shí),PLC即成為計(jì)算機(jī)的數(shù)據(jù)終端。
電業(yè)部門曾這么使用PLC,用以實(shí)時(shí)記錄用戶用電情況,以實(shí)現(xiàn)不同用電時(shí)間、不同計(jì)價(jià)的收費(fèi)辦法,鼓勵(lì)用戶在用電低谷時(shí)多用電,達(dá)到合理用電與節(jié)約用電的目的。
5用于進(jìn)行監(jiān)控
PLC自檢信號(hào)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?duì)象進(jìn)行監(jiān)控。
這里介紹一種用PLC定時(shí)器作看門狗,對(duì)控制對(duì)象工作情況進(jìn)行監(jiān)控的思路。
如用PLC控制某運(yùn)動(dòng)部件動(dòng)作,看施加控制后動(dòng)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(shí),令看門狗定時(shí)器計(jì)時(shí)。如在規(guī)定的時(shí)間內(nèi)動(dòng)作完成,即定時(shí)器未超過警戒值的情況下,已收到動(dòng)作完成信號(hào),則說(shuō)明控制對(duì)象工作正常,無(wú)需報(bào)警。
