III-4.7 MONO (monoflop (No. 66))
The function generates a positive pulse of length Ti
1
at output z1, when a positive flank at trigger input d1 is detected.
It generates a positive pulse of length Ti
2
at output z3, when a negative flank at trigger input d2 is detected.
Pulse duration Ti
1
is adjusted either as parameter Ti1 or read in via inputs Ti1. The origin of pulse duration is selected
via parameter Mode 1. The duration of an output pulse is matched to the new values with changes at inputs Ti1/Ti2.
With input values Ti1/Ti2 ß 0, the pulse is output for the duration of one scanning cycle.
The function is re-triggerable. I.e., if a new trigger condition is detected during a pulse output, the remaining pulse
time to be output is prolonged to a full pulse length.
The pulse duration accuracy is dependent of the sampling time, which is assigned to the function.
Example:
Ti = 0,9s for assignment to
- sampling interval 100ms means that the signal is output during = 0,9s.
- Sampling interval 200ms means that the signal is output during = 1,0s.
- Sampling time 400ms means that the signal is output during = 1,2s.
- Sampling interval 800ms means that the signal is output during = 1,6s.
Inputs/outputs
Digital inputs
