DATA LOGGING
Data logging will be done in the
LogBox Wi-Fi
internal memory. 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
recording the digital input event.
Any channel types (analog and digital in the "Pulse Count" or "Event Log" modes) can be logged in memory. In the case of analog channels logs or
digital input in "Pulse Count" mode, the logging will be periodic and will have its range configured through the configurator software. At the end of
each log range, the current values of the enabled channels will be logged in the memory. In case the digital input is configured in the "Event Log"
mode, the detected logs detected will be performed asynchronously to the periodicity of the other channels and will be performed when the event
occurs.
There are several ways to start and end logs and many of them can be combined freely. During logging, all selected channels will be logged in the
memory and the range between logs will be respected.
Depending on the type of start and end 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.
The device works with circular memory, which allows records to be continuously made. Once the memory is full, the oldest data will be paid so that
the most recent data can be saved.
First, you must configure the start mode, chosen from the options below:
●
Immediate Start:
Allows logs to be started shortly after the device is reconfigured.
●
Date/Time:
Allows logs to be started at the configured date/time.
●
By Keyboard:
In a screen in the display, you can change the logs status to
enabled,
which start the logs (in case they had not been started
yet).
●
By Digital Input:
Allows logs to be initiated from the digital input. For this option to be available, the digital input channel must have been set to
"Logs Control" mode. There are four modes for controlling the digital input:
○
Start the logs at each rising edge.
○
Start the logs at each falling edge.
○
Log at logical level ‘1’, which logs while at logical level ‘1’.
■
In this mode, the configured end mode should be "Logical level pause ‘0’".
○
Log at logical level ‘0’, which logs while at logical level ‘0’.
■
In this mode, the configured end mode should be "Logical level pause ‘1’".
●
By Software:
Allows logs to be started using an
NXperience
command.
●
Daily:
It allows the logs to be started every day and at the configured time. The "Daily" log start mode also requires a "Daily" log end mode.
●
By Alarm:
Allows logs to be started from a specific alarm.
And you must configure the end mode, chosen from the options below:
●
Non-Stop:
Allows logs to continue indefinitely. When filling memory, the oldest data will be deleted so that the most recent ones can be saved.
●
Date/Time:
Allows logs to be ended at the configured date/time.
●
By Keyboard:
In a screen in the display, you can change the logs status to disabled
,
which start the logs (in case they had not been started
yet).
●
By Digital Input:
Allows logs to be ended from the digital input. For this option to be available, the digital input channel must have been set to
"Logs Control" mode. There are four modes for controlling the digital input:
○
Pause logs at each rising edge.
○
Pause logs at each falling edge.
○
Pause at logical level ‘0’, which pauses while at logical level ‘0’.
■
In this mode the configured start mode should be "Logs in Logical level ‘1’".
○
Pause at logical level ‘1’, which pauses while at logical level ‘1’.
■
In this mode the configured start mode should be "Logs in Logical level ‘0’".
●
By Software:
Allows logs to be started using an
NXperience
command.
●
Daily:
It allows the logs to be paused every day and at the configured time. The "Daily" log end mode also requires a "Daily" log start mode.
●
By Alarm:
Allows logs to be stopped from a specific alarm.
