The on-delay time and off-delay time set in parameter TH and TL can be provided by the actual value of
another already-programmed function:
Analog comparator: Ax – Ay
Analog trigger: Ax
Analog amplifier: Ax
Analog multiplexer: AQ
Analog ramp: AQ
Analog math: AQ
PI controller: AQ
Data latching relay: AQ
Up/Down counter: Cnt
The value of "TH","TL"can be set/modified in parameter mode. For information about how to modify,
refer to chapter 7.2.2 please.
For information on the validity and accuracy of the time base, refer to 7.4.2
Timing diagram
Description of the function
The time T
H
is triggered with a 0 to 1 transition at input Trg.
If the status at input Trg is 1 at least for the duration of the configured time T
H
, the output is set to logical 1
upon expiration of this time (output is on delayed to the input signal).
The time T
H
is reset if the status at input Trg is reset to 0 before this time has expired.
The time T
L
is triggered with the 1 to 0 transition at the output.
If the status at input Trg remains 0 at least for the duration of a configured time T
L
, the output is reset to 0
upon expiration of this time (output is off delayed to the input signal).
The time T
L
is reset if the status at input Trg is returns to 1 before this time has expired.
