1. Bit 0 in CR4/CR32/CR60/CR88: If bit 0 in CR4/CR32/CR60/CR88 is turned ON, the input
contacts will be normally-closed contacts. If bit 0 in CR4/CR32/CR60/CR88 is turned OFF, the
input contacts are normally-open contacts.
2. Bit 1 in CR4/CR32/CR60/CR88: If bit 1 in CR4/CR32/CR60/CR88 is turned ON, the function of
prescaling the number of input pulses will be enabled. If bit 1 in CR4/CR32/CR60/CR88 is
turned OFF, the function of prescaling the number of input pulses will be disabled.
The function of prescaling the number of input pulses converts the number of input pulses into
the corresponding physical quantity.
