Pulse Outputs
Section 5-3
PULSE WITH VARIABLE
DUTY FACTOR: PWM(891)
PWM(891) is used to output pulses with the specified duty factor.

Reading PV
(D and D+1)
After the pulse output PV is read, the 8-digit hexadecimal
data is stored in D and D+1. (D contains the rightmost 4
digits and D+1 contains the leftmost 4 digits.)
