The following possibilities to start and stop loggings are available:
Logging start
Immediate Date/Time Alarm
Only Modbus
command
Logging stop
Full memory Yes Yes Yes Yes
Circular
memory
Yes Yes No Yes
Date/Time Yes Yes No No
Alarm Yes Yes Yes No
Here are operation details for each of these modes:
• Immediate start and stop when memory gets full: As soon as the new configuration is applied, loggings are
started. The FieldLogger follows on logging until filling up the memory (internal or SD card). In the case of a
power failure, logging is interrupted, returning as soon as power returns.
• Immediate start and never stops (circular memory): As soon as the new configuration is applied, loggings are
started. The FieldLogger goes on logging forever, overwriting the oldest data as soon as the memory has no
more room for new logs. In the case of a power failure, logging is interrupted, returning as soon as power returns.
• Immediate start and stop by date/time: As soon as the new configuration is applied, loggings are started. The
FieldLogger goes on logging until the arriving of the date and time set. In the case of a power failure, logging is
interrupted, returning as soon as power returns. If the memory fills up before the date/time set, FieldLogger will
stop logging.
• Immediate start and stop by alarm: As soon as the new configuration is applied, loggings are started. The
FieldLogger goes on logging until an alarm condition takes place (configured alarm for loggings stop). When
leaving alarm condition, loggings return to be done. In the case of a power failure, logging is interrupted, returning
as soon as power returns. When memory fills up, FieldLogger will stop logging.
• Start by date/time and stop when memory gets full: Once the date/time set for loggings start has arrived, loggings
will start. FieldLogger goes on logging until filling up the memory (internal or SD card). In the case of a power
failure, logging is interrupted, returning as soon as power returns.
• Start by date/time and never stops (circular memory): Once the date/time set for loggings start has arrived,
loggings will start. FieldLogger goes on logging forever, overwriting oldest data as soon as the memory has no
more room for new logs. In the case of a power failure, logging is interrupted, returning as soon as power returns.
• Start by date/time and stop by date/time: Once the date/time set for loggings start has arrived, loggings will start.
FieldLogger goes on logging until the arriving of the date and time set. In the case of a power failure, logging is
interrupted, returning as soon as power returns (in case the stop date/time has not yet elapsed). If the memory
fills up before the set up date / time, FieldLogger will stop logging.
• Start by date/time and stop by alarm: Once that the date/time set for the loggings start has arrived, loggings will
start. FieldLogger goes on logging until an alarm condition takes place (configured alarm for loggings stop).
When leaving alarm condition, loggings return to be done. In the case of a power failure, logging is interrupted,
returning as soon as power returns. When memory fills up, FieldLogger will stop registering.
• Start by alarm and stop when memory gets full: When an alarm condition takes place (configured alarm for
logging start), logging is started (it will not start if, upon applying the configuration, the alarm condition is already
satisfied: it must exit the alarm condition and get into it again.) FieldLogger goes on logging until filling up the
memory (internal or SD card). In the case of a power failure, logging is interrupted, returning as soon as power
returns.
• Start by alarm and stop by alarm: When an alarm condition takes place (configured alarm for logging start),
logging is started (it will not start if, upon applying the configuration, the alarm condition is already satisfied: it
must exit the alarm condition and get into it again). FieldLogger goes on logging while this alarm condition is met.
When leaving the stop alarm condition, logging is stopped. In the case of a power failure, logging is interrupted,
returning as soon as power returns. When memory fills up, FieldLogger will stop logging.
• Start only by Modbus command and stop when memory gets full: When the Modbus command for the logging
start is sent to the device (more details about this command in the document "FieldLogger – Modbus” and in the
chapter "Configuration and Download Software", "Diagnostics" section), logging will start. FieldLogger goes on
logging until filling up the memory (internal or SD card). In the case of a power failure, logging is interrupted,
returning as soon as power returns.
• Start only by Modbus command and never stops (circular memory): When the Modbus command for the logging
start is sent to the device (more details about this command in the document "FieldLogger – Modbus” and in the
chapter "Configuration and Download Software", "Diagnostics" section), logging will start. FieldLogger goes on
logging forever, overwriting the oldest data as soon as the memory has no more room for new logs. In the case of
a power failure, logging is interrupted, returning as soon as power returns.
