To do this, please follow these steps:

1. Switch "Trigger Mode" to "On" and
2. Select the "Trigger Source", e.g. "Line5".
3. Use "Counter1" and count the number of input trigger by setting the "Counter Duration" to "2".
4. Afterwards, start "Timer1" at the end of "Counter1":

The "Timer1" appears every second image.

Now, you can assign "Timer1Active" to a digital output e.g. "Line3":
