Data Logger
DCS500B also includes a datalogger for measurements. Data log-
ger has six logging channels. The capacity of each channel is 1000
samples.
DATA LOGGER func-
tion block
Data logger consists of six logging channels
DLOG1.[IN] (601)
DLOG2.[IN] (602)
DLOG3.[IN] (603)
DLOG4.[IN] (604)
DLOG5.[IN] (605)
DLOG6.[IN] (606)
The capacity of each channel is 1000 samples. These channels can
be used to collect fast incidents from the DCS500B within a certain
time. The total collection time (1...1000s) can be set with a sampling
interval parameter
DLOG.SAMPL INT (610)
(1...1000ms). This
collection time is common for all the channels.
Channels can be examined in graph/numeric form with the
CMT/DCS500 Tool.
Selection of the parameter/signal index to be sampled in the data
logger channels 1...6 is made by setting the index to the desired
connection point
DLOG1.[IN] (601) ... DLOG6.[IN] (606).
Selection of the trigger condition is made by means of the parame-
ter
DLOG.TRIGG COND (607)
as follows:
0
= external triggering
1
= fault + external triggering
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)
3
= triggers when the value in data logger
channel 1
exceeds the
value which is defined in
DLOG TRIGG VALUE (608)
4
= triggers when the value in data logger
channel 1
falls below the
value which is defined in
DLOG TRIGG VALUE (608)
.
Note!
Function blocks can be used to generate more complex trig-
gering conditions.
Number of samples
after triggering
can be defined by means of
parameter
DLOG.TRIGG DELAY (609),
0 ... 1000.
