Cyclic mode
Cyclic mode is used for generating periodically repeated pulses.
POUT1 CYCLIC:
out activ: low
T. : 00:00:02
L. : 00.10 sec
The value in field 'Time' determines the time between two consecutive pulses (2 sec
in example above). This cycle time must be entered as hours, minutes and seconds.
The pulse train is synchronized at 0:00 o'clock local time, so the first pulse of a day
always occurs at midnight. A cycle time of 2 seconds for example, would cause
pulses at 0:00:00, 0:00:02, 0:00:04 etc. Basically it is possible to enter any cycle time
between 0 and 24 hours, however only a cycle times that causes a constant distance
between all consecutive pulses make sense. For example a cycle time of 1 hour 45
minutes would generate a pulse every 6300 seconds (starting from 0 o'clock). The
duration between the last pulse of a day and the first pulse of the next day (0:00:00
o'clock) would only be 4500 sec.
PPS, PPM, PPH Modes
POUT1 Pulse Per
Sec (PPS):
out activ: low
L. : 00.10 sec
POUT1 Pulse Per
Min (PPM):
out activ: low
L. : 00.10 sec
POUT1 Pulse Per
Hour (PPH):
out activ: low
L. : 00.10 sec
These modes generate pulses of defined length once per second, once per minute or
one per hour.
'Time' determines the pulse duration (10 msec...10 sec) . The respective
output remains in active state, when selecting a pulse duration longer than 990ms
in pulse per sec mode..
