Retriggering the current Off-delay
The 2PULSE starts a new off-delay on the negative edge on the digital input DI if:
Off-delay > pulse duration + interpulse period.
This deletes the current on-delay.
The digital output DO is only deleted if signal level 0 is present on the digital input DI longer
than the off-delay.

Setting Times Using a Time Base
Use the assigned time base to select the resolution and the value range of the on-delay and
the off-delay.
Time base = 0.1 ms:
Time base = 1 ms:
Set the on-delay and change when using the short control interface
You specify the on-delay as a value between 0 and 65535 in the parameters.
Configured on-delay = Time base x specified numerical value
Using the factor for the on-delay, you can adjust the assigned time in your control program.
Set the factor between 0 and 255, with a weighting of 0.1:
On-delay = Factor x 0.1 x configured on-delay
If you change the on-delay factor, the new on-delay is activated with the next positive edge
on the digital input DI.
Setting and changing the off-delay
Set the off-delay directly as a numerical value between 0 and 65535 in your control program.
Off-delay = Time base x Specified numerical value
If you change the off-delay factor, the new Off-delay is activated with the next negative edge
on the digital input DI.
