Figure 215:Pushbutton with bounce
If a pushbutton or switch bounces (A), the delay time may be extended by
20 ms (16.7 ms) (A).
Delay time with DEBOUNCE deactivated
When DEBOUNCE is deactivated, the delay time is reduced so that the
easy800 device switches in shorter scan cycles t
(contact) internally from 0 to 1 (A) when a positive half wave is detected.

• Switch-on delay (normally):
• I1...I12: 20 ms (16.7)
• Off-delay (normally):
• I1...I12: 20 ms (16.7)
The corresponding values for 60 Hz are given in brackets.

A description of how to modify the delay times is provided in
the section (￫ Section 9.5, "Time behavior of the inputs and
outputs", Page 321).
