10 Pulse stretching
10.1 Overview of Registers
10.2 Operating principle
The pulse stretching feature means that the logic input state, which is read out by the
controller from the module, is stretched in time. That is, even when the input signal
is no longer applied, the logic input state of the module displays the input signal for
a certain time through its I/O number in the application program. Thus, even very
short input pulses can definitely be recognized in the application program.
