Configuration
Name
Description
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.
Scalar Average
(for Wind
Direction)
Logs the average of all samples taken over logging period, but uses scalar
calculations to calculate the average.
One Minute
Average
Logs the average of all samples taken over last minute prior to logging
Table 5 – Sensor Modes
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. The DC power change of state ignores this parameter, so it is
typically set to zero for this source as well.
Alarm Log Rate:
This is the logging rate (in mins) when the sensor is in alarm.
Reject Below (Low):
This option is used to enter a simple rejection value. Any value equal to or below this will be
ignored and the last “good” value retained.
Reject Above (High):
Any value equal to or above this will be ignored and the last “good” value retained.
Log if delta exceeds
+/-:
This is the amount the latest processed value (in actual engineering units of the sensor) must
differ from the last logged value in order to be logged.
The delta logging (if enabled by having a non-zero set-point) is done at the time the logging
would normally occur for the sensor as configured. All the delta decision does look at the last
value that was actually logged and compare it to the newly processed sample value. If the
difference is greater than the configured delta value, then the sample is actually logged.
First Routine Log
(hour):
This is the hour in the day when the first routine log will occur.
Routine Log Rate:
The routine log rate is the interval at which a routine log is taken after the first hour is reached.
Auxiliary Logging
Control:
You can also configure the extended datalogging options using the logging flags. The list of the
available flags are given below.
1. Log Minimum value sampled in the log period.
2. Log Maximum value sampled in the log period.
3. Log Calculated Flow Rate over log period or Log Accumulated Volume over log period.
4. Log Check Count.
