若超時(shí)，說明不正常，可作相應(yīng)處理。

如果控制對(duì)象的各重要控制環(huán)節(jié)，都用這樣一些看門狗"看"著，那系統(tǒng)的工作將了如指掌，出現(xiàn)了問題，卡在什么環(huán)節(jié)上也很好查找。

還有其它一些監(jiān)控工作可做。對(duì)一個(gè)復(fù)雜的控制系統(tǒng)，特別是自動(dòng)控制系統(tǒng)，監(jiān)控以至進(jìn)一步能自診斷是非常必要的。它可減少系統(tǒng)的故障，出了故障也好查找，可提高累計(jì)平均無故障運(yùn)行時(shí)間，降低故障修復(fù)時(shí)間，提高系統(tǒng)的可靠性。

3.6用于聯(lián)網(wǎng)、通訊

PLC聯(lián)網(wǎng)、通訊能力很強(qiáng)，不斷有新的聯(lián)網(wǎng)的結(jié)構(gòu)推出。

PLC可與個(gè)人計(jì)算機(jī)相連接進(jìn)行通訊，可用計(jì)算機(jī)參與編程及對(duì)PLC進(jìn)行控制的管理，使PLC用起來更方便。

為了充分發(fā)揮計(jì)算機(jī)的作用，可實(shí)行一臺(tái)計(jì)算機(jī)控制與管理多臺(tái)PLC，多的可達(dá)32臺(tái)。也可一臺(tái)PLC與兩臺(tái)或更多的計(jì)算機(jī)通訊，交換信息，以實(shí)現(xiàn)多地對(duì)PLC控制系統(tǒng)的監(jiān)控。
