5.5.2 Off-delay
Fashion: Classic:
Short description
The output with off delay is not reset until a defined time has expired.
Start the off delay time with a negative edge (1 to 0
transition) at input Trg (Trigger)
Reset the off delay time and set the output to 0 via the R
(Reset) input.
Reset has priority over Trg
T: The output is switched off on expiration of the delay
time T (output signal transition 1 to 0).
Retentivity on = the status is retentive in memory.
Q is switched on for the duration of the time T after a
trigger at input Trg.
Parameter
The time set in parameter T can be supplied by the 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 ＂T＂can be set/modified in parameter mode. For information about how to modify, refer to
chapter 5.2.2 please.
Select the required function by the block number. The time base is configurable. For
information on valid time base ranges and parameter preset, refer to chapter 4.4.1 the On-delay topic.
