Digital input /
output / bit
memory
• STATUS_ERROR
When there is an edge change 0 → 1 the On / Off delay
is stopped and the output is set to 0. As long as the input
is set to 0, the value of "Trigger" is ignored.
When there is an edge change 1
→ 0 the block can be
processed again.
With the setting "True" an edge change 0
→ 1 at "Trigger"
is permanently ignored. The "Off delay " function is there-
fore also turned off.
With the setting "False" the input is never active.
Function parameters
On delay (ms)
100 .. 999999999 On delay in milliseconds
After the On delay has elapsed, the output is set to 1.
Off delay (ms) 100 .. 999999999 Off delay in milliseconds
After the Off delay has elapsed, the output is set to 0.

5.6.4 Retentive on delay
Function
When there is an edge change 0 → 1 at the "Trigger" input, the configurable time of the On
delay is started. After the delay time has elapsed, the output is set to 1.
With this program block, if "Trigger" changes back to 0 before the delay time has elapsed,
the On delay is not stopped.
When there is an edge change 0
→ 1 at the "Reset" input during the On delay, the On delay
is stopped and the output remains set to 0.
When there is an edge change 0
→ 1 at the "Reset" input after the On delay has elapsed the
output is reset to 0.
