Time Sequence Frame:
Notes:
1. If the status of Input TRG changes from 0 to 1, the internal timer will be acti-
vated. When time T is over, Output Q becomes 1 and then the returned input TRG
has no effect on output Q .Only when Input R becomes 1 again Output Q and
Timer T will be reset to 0.
2. This function is applicable to the cases that the time-delay ON and hold ON
status are required.
3. The assignment range for T is 0.01 - 99.99, and the time units can be set respec-
tively to hour (H), minute (M) and second (S).
Its time accuracy can reach 0.5‰.

Input R
Input R takes priority over other inputs. When
it inputs a reset signal, the counter is reset to 0
and Q is reset simultaneously.
Input CNT
When CNT counting is input, the counter only
counts the leading edge triggering (the status
changes from 0 to 1), i.e. every time the lead-
ing edge is triggering, and the counter will be
increased by 1.
Output Q
When the counting value has been reached,
Output Q is On.
