 為了提高PLC控制系統(tǒng)工作的可靠性，可以專門(mén)設(shè)置一個(gè)定時(shí)器，作為監(jiān)控程序部分，對(duì)系統(tǒng)的運(yùn)行狀態(tài)進(jìn)行檢測(cè)。若程序運(yùn)行能正常結(jié)束，則該定時(shí)器就立即被清零；若程序運(yùn)行發(fā)生故障，如出現(xiàn)死循環(huán)等，該定時(shí)器在設(shè)定的時(shí)間到就無(wú)法清零，此時(shí)PLC發(fā)出報(bào)警信號(hào)。在設(shè)計(jì)應(yīng)用程序時(shí)，使用這種方法來(lái)實(shí)現(xiàn)對(duì)系統(tǒng)各部分運(yùn)行狀態(tài)的監(jiān)控。如果用PLC來(lái)控制某一對(duì)象時(shí)，編制程序時(shí)可定義一個(gè)定時(shí)器來(lái)對(duì)這一對(duì)象的運(yùn)行狀態(tài)進(jìn)行監(jiān)視：該定時(shí)器的設(shè)定時(shí)間即為這一對(duì)象工作所需的時(shí)間；當(dāng)啟動(dòng)該對(duì)象運(yùn)行時(shí)，同時(shí)也啟動(dòng)該定時(shí)器。若該對(duì)象的運(yùn)行程序在規(guī)定的時(shí)間結(jié)束工作，發(fā)出一個(gè)工作完成信號(hào)，使該定時(shí)器清零，說(shuō)明這一對(duì)象的運(yùn)行程序正常；否則，屬運(yùn)行不正常，發(fā)出報(bào)警信號(hào)或停機(jī)信號(hào)。

In order to improve the reliability of PLC control system, a timer can be specially set as part of the monitoring program to detect the running state of the system. If the program runs normally, the timer will be bed immediaby; If the program fails, such as dead cycle, the timer cannot be reset at the set time. At this time, PLC sends an alarm signal. When designing the application program, this b is used to monitor the running state of each part of the system. If PLC is used to control an b, a timer can be defined to monitor the running state of the b when programming: the setting time of the timer is the maximum time required for the b to work; When the b is started to run, the timer is also started. If the running program of the b finishes working within the specified time, send a work completion signal to reset the timer, indicating that the running program of the b is normal; Otherwise, it belongs to abnormal operation and sends out alarm signal or shutdown signal.
