Timing diagram
Description of the function
You can set the pulse/pause ratio at the TH (Time High) and TL (Time Low) parameters.
The INV input can be used to invert the output signal. The input block INV only inverts the output signal if the
block is enabled via EN.
If retentivity is not set, output Q and the expired time are reset after a power failure.
6.5.8 Random generator
Short description
The output of a random generator is toggled within a configurable time.
Connection
Description
Input En
The positive edge (0 to 1 transition) at the enable input En
(Enable) triggers the on delay for the random generator.
The negative edge (1 to 0 transition) triggers the off delay
for the random generator.
Parameter
TH: The on delay is determined at random and lies
between 0 s and T
H
.
TL: The off delay is determined at random and lies
between 0 s and T
L
.
Output Q
Q is set on expiration of the on delay if En is still set. It is
reset when the off delay time has expired and if En has not
been set again.
