10.4 XML import
The XML import is designed to import the data generated or changed via the user interface, created
by the customer, back into the myDatanet server.
l
Only existing measurement data and settings can be changed or new measurement data can
be added. No historical measurement data can be added.
l
It must be ensured that the
stamp
of the data records is always created in ascending order.
Errors can occur if this is not the case.
l
If any settings are changed, it must be ensured that the
stamp
is set to the current date/time.
Otherwise the data are not synchronised with the device.
l
When creating measurement data, the
id="0"
and
<tag>00002700</tag>
(27 representing the
device class) must always be specified.
l
<tag>0</tag>
must always be specified during the deleting process. Historical data (e.g.
measurement data) cannot be deleted.
10.4.1 Transferring data to the myDatanet server
A HTTP post command can be used to transfer a XML file to be imported by the myDatanet server.
A HTTP POST command can, for example, be executed with the freely available "Wget" command
line tool (http://www.gnu.org/software/wget/).
10.4.2 Configuration of a HTTP-POST command
Important note: The transmission of XML files to the server is completed via the HTTP server
(standard port 80) and not the xPath server (standard port 8080).
The HTTP-POST command is made up of the following:
http://{IP-Adresse}[:{Port}]/send.xml?directlogin={login}
The XML file must be transferred with this POST command. The configuration of these is described
in the chapter "Structure of the XML file" on page 107.
