Parameter Declaration Data type Memory block Description
IN INPUT BOOL I, Q, M, D, L, constant Start input
PT INPUT TIME I, Q, M, D, L, constant Time delay
Q OUTPUT BOOL I, Q, M, D, L Status of time
ET OUTPUT TIME I, Q, M, D, L Expired time
Start input:
The time delay is started by a rising edge at input IN results in a rising edge at output Q.
When a falling edge is applied to input IN output Q will also produce a falling edge when
delay PT has expired. If the level at input IN changes to "1" before time delay PT has
expired, then the level at output Q will remain at "1".
Time delay:
Time delay applied to the falling edge at input IN to PT must be. The range of values is
defined by the data type TIME.
Output Q:
The time delay is started by a rising edge at input IN results in a rising edge at output Q.
When a falling edge is applied to input IN output Q will also produce a falling edge when
delay PT has expired. If the level at input IN changes to "1" before time delay PT has
expired, then the level at output Q will remain at "1".
Expired time:
The time period that has expired since the most recent falling edge at input IN is available
from output ET. The highest value that output ET can reach is the value of input PT.
Output ET is reset when the level at input IN changes to "1".
