Fig. 22: Effect of pulse stretching with a signal of longer duration
If the duration of the input signal exceeds the pulse stretching interval, then, pulse
stretching has no effect. In this case, the length of the actual input pulse determines
the length of the stretched input pulse.
Once pulse stretching is deactivated, the actual input state is displayed.
The JX2-IO16 module provides two types of pulse stretching:
• Manual pulse stretching
• Automatic pulse stretching
Manual pulse stretching
With manual pulse stretching the input pulse is stretched until the application
program resets pulse stretching.
Automatic pulse stretching
With automatic pulse stretching the input pulse is stretched until the set pulse
stretching interval has elapsed.
