Measured value queries with the HTTP protocol
The 29 measured values of the Multi-E11/E4/E-MU can also be read out using the HTTP protocol, via the Internet
for example. Connect the measuring transformer to your PC via a LAN cable or to the Internet via a router (using
dynamic DNS, for example). Open a HTTP client on your PC. The addressing of the Multi-E11/E4/E-MU is via its IP
address or web address (e.g. "http://multi-e11-mu.dyndns.org/httpvalue.xml") and the request for file
"httpvalue.xml". The measuring transformer's reply is a string containing the measured data. The smallest interval
for reading out the values should not be less than 50 ms. The string with the measured values has a size of 301
bytes. All measured values are output in ASCII format along with the associated unit. Individual measured values
are separated by the semicolon sign (0x3B). The last character in the file is a blank (0x00). Decimal places in the
measured values are indicated with a dot (0x2E). By virtue of the ASCII format and semicolon-separation of values,
it is very easy to further process the measured values. The arrangement of the measured values in the string is as
follows:
