English
DELAY COMPARATOR
This operator compares the timer value
outputted by a LONG DELAY timer and
connected to the DELAY COMPARATOR
“Timer” input with the set threshold value.
The OUT output will be 0 (FALSE) as long as the
timer value is lower than the threshold value.
The OUT output will be set to 1 (TRUE) for Timer
values equal to or higher than the threshold
value.
Parameters
Threshold: The threshold can be set from 0,5 s to 54910 s.
Scale: The user can choose two different scales for the time T to be set.
• 0,5 s...3000 s, step 0,5 ms
• 3005 s...54910 s, step 5 s
➔ The Delay Comparator operator can only be connected to the Timer value output of a LONG
DELAY operator. Multiple DELAY COMPARATORS can be connected to each LONG DELAY
operator.
DELAY LINE
This operator applies a delay to a signal by setting the “Out”
output to 0 (FALSE) after the set time when a falling edge is
detected on the “In” signal.
If "In" returns to 1(TRUE) before the end of the set time the
“Out” output still generates a negative impulse lasting
approximately twice the system response time and delayed by
the set time.
Parameters
Time: The delay can be set to between 10 ms and 1098,3 s.
Scale: The user can choose two different scales for the time T to be set.
• 10 ms...60 s, step 10 ms
• 60 s...1098,3 s, step 100 ms
