In Time mode, records are made periodically on
“Log
interval”
time. In Alarm mode, records
are made on every alarm condition. In Time & Alarm mode, a mix of both conditions for records
is used.
The log interval determines the time between two log entries. It is good to remember that
by reducing the log interval, we increase the resolution, but we also reduce the past period for
which we have records. The internal memory holds 70,000 total readings so hourly records
would provide a history of almost 8 years using one channel, whereas a 1-minute logging
interval would provide a history of 48 days using one channel or 12 days using 4 channels
There are 3 ways to reach the logger records:
1.
Periodically upload the last unsent records to the dedicated HTTP server.
The records are uploaded in CSV file format. The period of the upload can be chosen from
the menu between 1 and 24 hours. If you enable this service, take care of the real-time
clock (NTP service).
The HTTP server for upload can be domain or IP address but take care about DNS settings.
“Sync
time”
is a moment in the day when a period of upload is synchronized.
Example:
Current time is 19:31, Upload period is 3 hours and Sync time is 9:00.
To synchronize the logger to 9:00 it means that time for uploads will be: 09:00, 12:00, 15:00,
18:00, 21:00, 24:00, 03:00 and 06:00. The first upload, after enabling the logger in 19:31, will
be in 21:00.
2.
Force upload
This button initiates an upload of the recorded information between previous periodical upload
and now.
3.
Download full log
Clicking the Download full log button will initiate a download of the log in csv format.
By default, the logger is disabled.
More about the logger can be found in the Data logger section.
7.3.2
HTTP Post
HTTP Post is used to periodically upload an XML/JSON file to HTTP server by HTTP requests
(POST method). The XML/JSON file contains the current status of all monitored parameters and
extra system information. The file format is chosen from the drop-down menu.
The HTTP server can be addressed either by domain name or IP address.
The period of the upload can be chosen from the menu between 1 and 24 hours. This
parameter can be changed remotely also by HTTP API. The "Period" determines at what
time the control software receives up-to-date information from OMNITEXT-240 and can,
therefore, make changes to some of the parameters. The shorter the "Period", the closer
to the real-time operation is the system. On the other hand, a shorter "Period" is higher
in the data traffic through the mobile network and the power consumption.
