88 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
