Http Server Functions/ Web Pages 

 

FP Web-Server V2.11 

74 

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 (see page 158), 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&Rxxy=w 

Before downloading the page yyy, the internal relay 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) 

http://199.199.26.52/plc?yyy&Y0=1&A=5&Y
0=1 

Composed types of commands are also possible! 

•  http://199.199.26.52/' can be omitted for relative hyperlinks in an .HTM (or .MTM). 
•  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. 

•  The functions &Y and &R can be limited with [Add. Range]. 
•  The name of the CGI function must be in small letters, i.e. 

"http://199.199.26.52/PLC?yyy" will not work. 

•  The PLC address of the &R and &Y commands cannot be replaced by a variable name, 

i.e. "http://199.199.26.52/plc?yyyeR'name'=1" will not work. For further information, 
refer to Using Variable Names Instead of Absolute PLC Addresses (see page 82). 

•  If spaces or Japanese characters are used, an error message pops up before 

transmission to the FP Web-Server. 

•  All file names have to correspond to the DOS 8.3 format, i.e. the name may only have up 

to 8 characters and the extension (type) only up to 3 characters after the period. 
(FP-WEB2 (see page 15): Long file names without special characters can be used.) 

For programming examples in C++ and Java to control PLC relays via the http function, please 
refer to the online help under the keyword "Appendix K) Programming Samples: Access to the 
FP Web-Server / PLC via TCP".
