错误比较读数所有模拟输入模块都容易受到错误比较读数的影响,这会增加故障的概率。通常,读数之间的差异越大,错误比较的时间越长,就越有可能宣布故障。模拟输入模块之间的差值和周期各不相同。•对于3700、3700A和3701型,如果读数相差满量程的至少2%,并持续至少40个输入样本,则故障概率增加。•对于3703E和3704E型,如果读数差异小为满量程的0.5%,并持续256个输入样本的小周期,则故障概率增加。•对于3720型,如果读数相差满量程的至少0.5%,并持续至少25个输入样本,则故障概率增加。•对于3721型,如果读数相差满量程的至少2%,并持续至少25个输入样本,则故障概率增加。
Mis-Compare Readings All Analog Input Modules are susceptible to mis-compare readings which can increase the probability of a fault. Generally, the greater the difference between readings and the longer the period of mis-compares, the more probable that a fault will be declared. The amount of difference and period varies among Analog Input Modules. • For Models 3700, 3700A, and 3701, if the readings differ by a minimum of 2 percent of full scale and continue for a minimum period of 40 input samples, the probability of a fault increases. • For Models 3703E and 3704E, if the readings differ by a minimum of 0.5 percent of full scale and continue for a minimum period of 256 input samples, the probability of a fault increases. • For Model 3720, if the readings differ by a minimum of 0.5 percent of full scale and continue for a minimum period of 25 input samples, the probability of a fault increases. • For Model 3721, if the readings differ by a minimum of 2 percent of full scale and continue for a minimum period of 25 input samples, the probability of a fault increases.
