4 Individual Measurement Polling
4.1.1 HTTP - Polling logger using a ASCII command string
It is possible to manually poll the current values in CSV format
using a socket connection (comma-delineated data). This
function is also used to poll the individual data without using
the Web interface.
To do this, send the following string to Port 80:
GET /logger.csv
This expression may also be given additional parameters that
determine the content:
start=ttmmyyyyThhmmss
Start date and time of the desired values.
end=ttmmyyyyThhmmss
End date and time of the desired values.
DTb=x&
Desired interval where x =
1 -> 15 sec.
2 -> 30 sec.
3 -> 1 min.
4 -> 5 min.
5 -> 15 min.
6 -> 60 min.
The expression must begin with „?“ after the filename. Each va-
riable must be separated with a „&“ .
Example:
http://<ip-address>/logger.csv?start=01012010T123000&end=30032010T200000&DTb=5&
This expression generates a CSV file containing the data from
01.01.2010, 12:30h up to 30.03.2010, 20:00h in 15 minute
intervals.
