Logging
XLink automatically logs the sensor data that it collects (see
). Data is logged on
secure flash memory with a capacity of over 1,000,000 entries. Each log entry uses an IEEE 64 double
precision float to represent the sensor reading.
Log usage and capacity information is available in the main status. For more details, use the STATUS LOG
command.
Measurement readings are logged according to the
Logging Interval
). Each measurement has its own logging interval.
Logged data will
not
be lost if power is removed. Once the log is full, the oldest data will be
overwritten.
Only logged data may be transmitted.
The system logs events such as power up, log download, and setup change.
When downloaded, the data is presented in Sutron Standard CSV format. It is a format common to current
Sutron products. A log entry looks like this:
04/02/2012,09:25:00,STAGE,20.50,FT,G
date and time (with a one-second resolution)
user set measurement label (STAGE)
measurement reading (20.50)
user set measurement units (FT)
measurement quality (G = good, B = bad)
The general format specification for Sutron Standard CSV format is:
mm/dd/yyyy,hh:mm:ss,label,data,units,quality
Here are some examples of log entries:
01/19/2015,09:30:00,Stage,1.25,ft,G
01/19/2015,09:45:00,Stage,1.27,ft,G
01/19/2015,09:50:27,Setup Change,,G
To help preserve data integrity and reliability, there is no way to erase data from the log.

Downloading the Log
Logged data can be downloaded using LinkComm or via a terminal program using the LOG command.
Additionally, plugging in a USB thumb drive into the station will automatically download the log.
