Pulse width modulation

Function
In the "pulse width modulation" operating mode, the four outputs only provide a pulse width
modulated output signal.
The digital channel is activated with a pulse duty cycle that is updated cyclically as a function
of the output value from the user program. The actuating signal is output digitally as a pulse
train of on and off pulses.
