HTTP address
Function
http://199.199.26.52/
Downloads MAIN.HTM (in MAIN.HTM you can
neither use PLC data fields nor password
protection)
http://199.199.26.52/zzz.HTM
Downloads HTML page zzz.HTM
http://199.199.26.52/plc?yyy
Downloads HTML page yyy.MTM including PLC
data. The file format .MTM is equivalent to the
.HTM format plus PLC data. The .MTM file is
generated by the Configurator.
http://199.199.26.52/plc?yyy&U=xx With automatic reload/update after xx
seconds. The maximum refresh rate is reached
with the input &U=0.
For rapidly changing PLC data, we recommend
using Java Applets, which can handle a much
higher data update/display rate.
http://199.199.26.52/plc?yyy&A=xx All following PLC data displayed (including
yyy.MTM) are addressed to the PLC with the
C-Net/MEWTOCOL Address xx (0..32). 0 is
equivalent to the universal address EE. The
default address (if no &A parameter is used)
can be determined in the base configuration
setting PLC MEWTOCOL Address. The &A
operator does not affect the default addressing
for input fields.
http://199.199.26.52/plc?yyy&I=xx All following PLC data displayed (including
yyy.MTM) are routed through the interface
with the specific number (). The &I operator
does not affect the default setting of the
interface for input fields.
http://199.199.26.52/plc?yyy&Rxxy
=w
Before downloading the page yyy, the internal
flag with the address Rxxy is set (w=1) or
reset (w=0). (xx=0...999, y=0...F, w=0/1)
http://199.199.26.52/plc?yyy&Yxxy
=w
Before downloading the page yyy, the output
with the address Yxxy is set/ reset.
(xx=0...999, y=0...F, w=0/1)

It is possible to combine different types of
commands!
Comments:
http://199.199.26.52/'
can be omitted for relative hyperlinks in an
.HTM (or .MTM) file.
Only when the HTTP server is turned on can the modification of PLC
data (via &Y and &R commands) be temporarily turned off. If an error
occurs, writing to the PLC may be prevented. Therefore, the functioning
of the Ys and Rs is also affected.
