DCS 500 Software Description
Example:
The data logger is used to monitor the speed difference during a
speed response test. The measurement points are
[STEP] (2002)
,
STEP RESP (12003)
. Triggering will take place when
[STEP]
(2002)
exceeds the set limit e.g. 10 (given step e.g. 100).
Settings:
DLOG1.[IN] (601)
connect to 2002
DLOG2.[IN] (602)
connect to 12003
DLOG.TRIGG COND (607)
= 2,
triggers when the difference between two successive values of data
logger
channel 1
is larger than the value defined in
DLOG.TRIGG
VALUE (608).
DLOG.TRIGG VALUE (608)
= 10
DLOG.TRIGG DELAY (609)
= 800
200 samples before and 800 samples after the triggering.
DLOG.SAMPL INT (610)
= 3ms, samples are taken 0.6 s
(200*3ms) before and 2.4 s (800*3ms) after triggering. Resolution
must be observed in setting of the sample interval; a too long inter-
val causes losses in the waveform during fast changes of the
measured signal.
The status of data logger can be read out from parameter
DLOG
STATUS (10601)
.
0 = logger is empty
1 = logger is collecting data
2 = a trigger has occured
3 = logger has stopped after a trigger
4 = logger has stopped after a stop command
5 = logger has stopped after a trigger and stop command
