Description
On delay time
0 … 300 s in 1-ms steps
1)
•
The delay time begins with a rising signal edge at the
Control
input.
If, after expiration of the configured delay time, the
Control
input is
still 1, the
Enable
output = 1.
•
If the
Control
input returns to 0 before expiration of the configured
switch-on delay time, the
Enable
output remains = 0. The timer for
the switch-on delay time is reset to 0.
1)
0 = No delay
Complementary information
If the configured delay time is less than or not a multiple of the logic execution time,
then the delay time extends to the next logic cycle.
If, during the first logic cycle, the
Control
input = 1 and a switch-on delay time > 0 is
configured, then the
Enable
output = 0. If the
Control
input remains at 1, then the
Enable
output remains 0 until the configured switch-on delay time has expired (Prerequisite:
First logic cycle < configured switch-on delay time).
7.6.2.3.2
Fixed off-delay timer V1
Overview
The function block delays switch-off of the
Enable
output by a configurable period of
time if a falling signal edge is present. The output is switched on without delay if a rising
signal edge is present.
