•
Sync interval = 15 minutes.
The settings determine 4 records per hour in HH:00 , HH:15, HH:30, and HH:45.
The device is powered up.
The first record will be immediately after power-up - 09:12. The next records will be in 09:15,
09:30, 09:45, 10:00, 10:15, etc.
There are two ways to reach the logger records:
•
download of the full log file , using “Download full log” in the WEB interface ;
•
periodical upload the last unsent records to the dedicated HTTP server.
The records are uploaded in CSV file format using HTTP or HTTPS protocol. The HTTPS upload is
over TLS 1.0, TLS 1.1 and TLS 1.2 with RSA as a key exchange/agreement and authentication.
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 u pload 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.
The button “Force upload” initiates upload recorded information between previous periodical
upload and now.
By default, the logger is disabled.
More about the logger can be found in the Data logger section.
7.3.3. HTTP post
TCW220 can periodically upload a file to a dedicated server using HTTP or HTTPS Post. The HTTPS
is over TLS 1.0, TLS 1.1 and TLS 1.2 with RSA as a key exchange/agreement and authentication.
The period of the post is between 10 and 14400 seconds. The file format can be XML or JSON.
By default, Periodic&Alarm is selected as the mode. In addition to the periodic posts, a file can be
uploaded at any alarm condition.
If Periodic only is selected as the mode, then periodic posts are performed without alarm posts.
If Alarm only is selected as the mode, then alarm posts are performed without periodic posts.
The “Key” field value is sent in the XML/JSON and can be used for device identification.
If “Process Answer” option is enabled, the TCW220 will process the answer of the remote server.
The list of valid commands is described in section “ HTTP API commands ” .
