PSCCM22AAN 16418-5312設(shè)置警戒時鐘wdt：機(jī)械設(shè)備的動作時間一般是不變的，可以以這些時間為參考，當(dāng)plc發(fā)出控制信號，相應(yīng)的執(zhí)行機(jī)械動作，同時啟動一個定時器，定時器的設(shè)定值比正常情況下機(jī)械設(shè)備的動作時間長20%，若時間到，plc還沒有收到執(zhí)行機(jī)構(gòu)動作結(jié)束信號，則啟動報警。
PSCCM22AAN 16418-5312提高輸入信號的可靠性：由于電磁干擾、噪聲、模擬信號誤差等因素的影響，會引起輸入信號的錯誤，引起程序判斷失誤，造成事故，例如按紐的抖動、繼電器觸點(diǎn)的瞬間跳動都會引起系統(tǒng)誤動作，可以采用軟件延時去抖。對于模擬信號誤差的影響可采取對模擬信號連續(xù)采樣三次，PSCCM22AAN 16418-5312采樣間隔根據(jù)a/d轉(zhuǎn)換時間和該信號的變化頻率而定，三個數(shù)據(jù)先后存放在不同的數(shù)據(jù)寄存器中，經(jīng)比較后取中間值或平均值作為當(dāng)前輸入值。

Psccm22aan 16418-5312 ? set the alarm clock WDT: the b time of mechanical equipment is generally unchanged, which can be used as a reference. When PLC sends a control signal, execute the mechanical b accordingly, and start a timer at the same time. The set value of the timer is 20% longer than the b time of mechanical equipment under normal conditions. If the time is up, If the PLC has not received the b end signal of the actuator, it will start the alarm.
Psccm22aan 16418-5312 improve the reliability of the b signal: due to the influence of electromagnetic interference, noise, analog signal error and other factors, it will cause the error of the b signal, cause the error of program judgment, and cause accidents. For example, the jitter of the button and the instantaneous jump of the relay contact will cause the system misoperation. The software delay can be used to remove the jitter. For the influence of analog signal error, the analog signal can be sampled three times continuously. The sampling interval of psccm22aan 16418-5312 is determined according to the A / D conversion time and the change frequency of the signal. The three data are successively stored in different data registers. After comparison, the intermediate value or average value is taken as the current b value.
