Device
D1062
Function
Average number of times analog input signals are input through CH0~CH3 of
20EX2/SX2: 1~20, Default = K2
Average number of times analog input signals are input through CH0~CH2 of
30EX2: 1~15, Default = K2
D1110 Average value of EX2/SX2 analog input channel 0 (AD 0)
D1111 Average value of EX2/SX2 analog input channel 1 (AD 1)
D1112 Average value of EX2/SX2 analog input c hannel 2 (AD 2)
Average value of 20EX2/SX2 analog input channel 3 (AD 3)
If D1062 is ON, the average value is the current value.
