Retriggering the Off delay
In the following case, the module cancels the current Off delay and restarts it with the next
rising edge at digital input DIn.0:
Off delay > Pulse duration + Interpulse period
The following figure shows an example of the retriggering of the Off delay:
Figure 4-8
4.4.1.3
On delay
You set the duty cycle in the control interface (Page 89) using OUTPUT_VALUE as integer
(UDINT). The value range is 0 to 85 s with a precision of 1 µs.
A change takes effect on the next rising edge at digital input DIn.0.
4.4.1.4
Off delay
You set the Off delay from 0 to 85 s with a precision of 1 µs in the hardware configuration.
In addition, you can change the OFF delay via the control interface by entering a new value
in SLOT as integer (UDINT). In so doing, you use the MODE_SLOT control bit to choose
whether you want to apply a change once or cyclically:
MODE_SLOT = 0
MODE_SLOT = 1
You can find additional information under Handling of the SLOT parameters (Page 139).

Retriggering the Off delay
One-time change:
As soon as you write the value 3
from SLOT is applied once as the OFF delay and kept until the next change.
A change using SLOT takes effect on the next falling edge at digital input DIn.0.
Cyclic change:
When you write the value 19
value from SLOT in each case is applied cyclically as the Off delay.
A change using SLOT takes effect on the next falling edge at digital input DIn.0.
