TCW242-S_R1.0 – July 2021 Page 22
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:
The current time is 19:31, the Upload period is 3 hours and the 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 at 19:31, will
be at 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 Datalogger section.
8.3.4. HTTP Post
TCW242-S can periodically upload an XML/JSON 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 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/HTTPS Post can be sent up to 3 independent servers. The HTTP servers can be
addressed either by domain name or IP address.
The “Period” can be set between 10 and 14400 seconds. 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 TCW242-S and can, therefore, make changes to some of the
parameters. The shorter is "Period", the closer to the real-time operation is the system. On the
other hand, as shorter is the "Period" as higher is the data traffic through the network.
If the checkbox “Connect on any alarm” is selected, the HTTP/HTTPS Post request will be sent in
an alarm condition.
