Sutron Corporation Satlink Operations & Maintenance Manual, Rev 8.04.2 11/3/2016 pg. 95
LinkComm provides a
Log All
checkbox: when checked Satlink will measure and log at the
Measurement Interval.
Having a
Logging Interval
that is shorter than the
Measurement Interval
is a bad setup.
Only logged readings may be transmitted.
It is not possible to entirely disable logging of measurement results. However, one can set the
logging interval as slow as once a day.
9.7.2.
Log Error Value
When Satlink cannot get valid data from a sensor (more specifically, when a sensor failure error
occurs), Satlink will change the sensor reading to match the user-set
Log Error Value,
which
defaults to -99999. Such atypical numbers are used to attract the user’s attention when viewing
the log.
9.7.3.
Transmission Data Content Settings
9.7.4.
Tx Data Content
Tx Data Content
tells Satlink which readings to include in the transmission. Each measurement
has the
Tx Data Content
setting.
The options are All, Individual, Last, and Exclude.
By selecting
All
, all the measurements that are logged are also set to be transmitted.
Only readings made since the last transmission are included. This setting is dependent
on the Log Interval setting.
Last
means to transmit a set number of the most recent readings (determined by
Number of Values to Tx
).
Use
Last
for alarm transmissions to ensure that the value that caused alarms is
transmitted!
By selecting
Exclude
, no readings of this measurement are transmitted.
See Tx Data Time and Interval below for the Individual setting.
9.7.5.
Tx Data Time And Interval
If
Individual
is selected for
Tx Data Content
, the fields
Tx Data Time
and
Tx Data Interval
will
appear, allowing the choice of what data to include in the transmission.
This options should only be used to measure and log data more frequently than to include it in
transmissions. For example, if one wanted to measure and log data once a minute, one would set
the
Measurement and Logging Intervals
to one minute. Since it may be expensive to transmit all
that data, one can choose to transmit only every 10th reading by setting the
Tx Data Interval
to
00:10:00.
The example below uses Measurement and Logging Intervals of 15 minutes. Tx Data Content is
set to Individual.
