HTTP server functions/web pages
FP Web-Server V2.810 EN 85
The functions &Y and &R can be limited with [Add. Range] (see p. 118).
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 p. 96).
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 p. 16): Long file names
without special characters can be used.)
For programming examples in C++ and Java to control PLC flags 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".
