DATA REGISTERING
Data registering will be done in
LogBox BLE
’s internal me
mory. The internal memory capacity is up to 140,000 logs. The number of logs that can
be stored in the internal memory depends basically on the
number of input channels that are enabled, as well as factors such as recording or not
re
cording the digital input event.
Any channel types (a
nalog or digital in "Pulse Count" or "Event Log" modes) can be recorded in the memory. In the case of analog channel logs or
the digital input in "P
ulse Count" mode, the log is periodic and has its interval configured through the configurator software. At the end of each log
interval, the current
values of the enabled channels are logged in the memory. In case the digital input is configured as "Event Log", the logs
detected by it will be
performed asynchronously to the frequency of the other channels and will be performed at the moment the event occurs.
There are several wa
ys to start and stop logs, many of which can be combined freely. During registering, all selected channels will be logged in the
memory and the range between logs will be respected.
Depending on the ty
pe of start and stop selected, there may be log "snippets" in the memory and, therefore, periods with no logged data. This is
fully compatible with the device and is not a problem at all.
In addition to the start and stop modes, you must also config
ure the memory mode, which can be:
●
Circular Me
mory:
Logs will be made continuously in the selected memory. When the memory is full, the oldest data will be erased so that the
most recent data can be saved.
●
Full Me
mory:
Lo
gs are terminated when the memory has no more space available.
The available start modes are as follows:
●
I
mmediate Start:
The logs will start immediately after rec
onfiguring the device.
●
By Date/Ti
me:
The logs will start in the configured date/time.
●
By Keyboard:
Th
ere is a screen in the display where you can change the log status to
enabled
. Therefore, the logs will start at this point if they
are not already st
arted.
●
By Digital Input:
When the digital input is triggered, th
e logs are started. In this case, the digital input channel must have been set to "Logs
Control" mode. To control the logs by digital input, four m
odes are possible:
○ Starts logs at each rising edge;
○ Initiates logs at each falling edge;
○ Logs at logical level "1" (logs while at logical level "1");
■ In this mode the configured stop mode should be "By Digital Input" too.
○ Logs at logical level "0" (logs while at logical level "0");
■ In this mode the configured stop mode should be "By Digital Input" too.
●
By Soft
ware:
Log
s are started with an
NXperience Mobile
or
NXperience
command.
●
Daily:
The logs ar
e started every day, at the configured time. A "Daily" log start mode also requires a "Daily" log stop mode.
The available stop modes are as follows:
●
Me
mory Mode Only:
The configuration chosen for the memory mode will dictate the logs behavior: if
"Full Memory" is chosen, the logs will end
as soon as there is no more memory space; if "Circular Memory
" is chosen, the logs will continue indefinitely.
●
By Date/Ti
me:
The logs will be finalized at the configure
d date/time.
●
By Keyboard:
There is a screen in the display where yo
u can change the log status to
disabled
. Therefore, the logs will be paused at t
his point
if they are not alre
ady paused.
●
By Digital Input:
When the digital input is triggered, the logs are ended. In this case, the digital input channel must have been set to "Logs
Control" mode. To control the logs by digital input, four modes are possible:
○ Pauses logs at each rising edge;
○ Pauses logs at each falling edge;
○ Pauses at logical level "0" (pauses while at logical level "0");
■ In this mode the configured start mode should be "Logs in Logical level "1"".
○ Pauses at logical level "1" (pauses while at logical level "1");
■ In this mode the configured start mode should be "Logs in Logical level "0"".
●
By Soft
ware:
Log
s are ended with an
NXperience Mobil
e
or
NXperience
command.
●
Daily:
The logs ar
e paused every day, at the configured time. A "Daily" log stop mode also requires a "Daily" log start mode.

Logs Maximum Capacity
143,147 logs from 1 channel
111,336 logs from 2 channels
91,093 logs from 3 channels
77,079 logs from 4 channels
66,802 logs from 5 channels
58,943 logs from 6 channels
* Each channel is rec
orded in a 16-bit space, except the digital channel accumulator mode that occupies 32 bits (that is, it is equivalent to two 16-bit
channels).
Exa
mple:
A log with 2 analog ch digital channel (av
erage in the range) + digital channel (accumulator) corresponds to 5 channels.
