11. Annex
12. Data communication met[LOG] by HTTP
12.1. Identification of the logger
The data communication takes place exclusively via HTTP via the LAN interface.
The identification of the logger and the channel assignment takes place via the call of the web page
„statdef.htm“
The page „statdef.htm“
has got the following structure
:
<HTML>
<HEAD><meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<TITLE>statdef</TITLE>
</HEAD>
<BODY>
<PRE> ..... </PRE>
</BODY>
</HTML>
As a block
<PRE> …. </PRE>
will the data be transferred:
•
Station name
•
Number of the transferring sensors (incl. virtual sensors)
•
Date (hh:mm:ss,yyyy.mm.dd)
•
Sensor name 1
•
Unit 1
•
Decimal places 1
•
Sensor type 1
