3.4.7.2 Logging
Sample Rate: The sample rate is the rate (in secs) at which the source is sampled.
Process Mode: Choose the process mode to apply to the measurements. The available modes are:
Name Description
Instant Logs only the most recent sample.
Event (Only valid for pulse input sources) Logs non-zero samples.
If the logging rate is 0, then any pulse is logged immediately.
If the logging rate is > 0, then the total accumulated in the period is
logged only if it is not zero. In this mode, if there was no sample logged at
the last log time, a zero sample is also logged, time stamped with last log
time/date. This is required for time series management purposes.
Period Average Logs the average of all samples taken over logging period.
Partial Period
Average
Logs are averaged of the duration period of the time defined by the
Duration setting (see below), not the full logging period. The averaging
occurs in the proceeding number of minutes before the logging event.
Scalar Average
(for Wind
Direction)
Logs the average of all samples taken over logging period, but uses scalar
calculations to calculate the average.
Log Rate: This is the logging rate (in mins) when the sensor is not in alarm. If you wish to log digital data
on change of state you can enter a value of 0. If this parameter is left at 0 for analogue
sources, they will not be logged.
Alarm Log Rate: This is the logging rate (in mins) when the sensor is in alarm.
