HTTP server functions/web pages The HTML page "MAIN.HTM" of the FP Web-Server will be displayed. For the "default_project" (without PLC data, FP Web-Server may not be connected to a PLC) for example: Or 'Example - First web page with PLC data': 12.1.2 Internet browser settings If the FP Web-Server is operated in an office network with a Proxy gateway to the Internet, the access to the FP Web-Server HTML pages might take a long time.
HTTP server functions/web pages 12.1.3 Generalities on PLC data fields in HTML pages "Example - Web pages and e-mail" (provided in your installation directory) is used for the following explanation: Here you see the HTML page 'MAIN.HTM' of the FP Web-Server. By clicking the links you can test the individual pages. For example, by clicking [Display] the DT200 page (with PLC data) is displayed: Click [On] or [Off] to set the output of the PLC.
HTTP server functions/web pages 12.1.4 HTTP address, CGI function PLC and calling parameter Please also note the display/input in the "Location" field: "http://199.199.26.52/plc?dt200" of the browser. Using the parameter following the IP address, you can control various functions. 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.
HTTP server functions/web pages 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. 95).
HTTP server functions/web pages 12.1.6 Editing HTML pages All web pages the FP Web-Server is supposed to display should be created and/or edited on a computer. To do so, it would be best to mark the respective file of the project in the Configurator in the "Web" screen and start the preinstalled editor of the operating system by double-clicking (or pressing or [Open]). For detailed information, please refer to Configurator HTTP administration and functions (see p. 116).
HTTP server functions/web pages The first HTML page that displays PLC data could look as follows (text file): HTML editor: Standard HTML editors like "KompoZer" and "MS-Word" provide many user-friendly functions to design HTML pages. Many browsers also provide an integrated editor.
HTTP server functions/web pages 12.1.7 Compiling and transferring HTML pages To insert PLC data fields into an HTML page, the PLC address information is enclosed in {...} curly brackets. You will find a detailed description of the format of the {...} PLC data fields in the following section. If an HTML page with {...} PLC data fields has been created/ changed, it has to be transformed into an .MTM file by the "HTML-Compiler" and transferred to the FP Web-Server afterwards.
HTTP server functions/web pages Number of display locations on the page (for numbers) Specification of the format displayed (format of numbers or text ON/OFF for internal flag) The {...} fields can only be seen in the HTML editor (ASCII Text Editor) and are replaced by the respective number of spaces by the "HTML-Compiler". Such a file is then named an .MTM file and saved on the FP Web-Server.
HTTP server functions/web pages The setup of the field for PLC data display always has the format {TTxxxy_aa_bb} (for FP7 {TTxxxxy_aa_bb}) with the following parameters: TT PLC Data Type. Implemented PLC data identifiers: DT, FL, LD, WI, R, X, Y xxxy Address of the PLC Data, e.g. DT200 or Y7. The address range supported by the FP Web-Server is 0–32765. For internal flags, the last position of the address is a hexadecimal number from 0–F, e.g. R2F For FP7, the supported address range is 0–999424.

Format PLC value Display {DT201_7_.3i} DT201=1234 1.234 {DT201_6_.4d} DT201= -12 -0.
HTTP server functions/web pages 12.1.8.2 Comments The PLC data tag can also be used in XML files for data exchange. Please find details under "Notes on XML files with PLC data (see p. 113)". In the text parameters aa and bb, which specify texts for the internal flag's statuses, it is also possible to use complex HTML blocks, e.g. to display graphics. Please do not use special characters and umlauts in {...} PLC data fields (and/ or the format parameters aa and bb).
HTTP server functions/web pages If an HTML page from the FP Web-Server is requested by the browser, but the PLC data cannot be read out from the PLC (wrong baud rate, problems with cables...), an HTML page with an error message will be displayed instead of the requested page. If an HTML page with PLC data shows Err 1 then the field length of the data is too low. E.g. {DT200_5_ld} and the value of DDT200 is 31235933.
HTTP server functions/web pages If an HTML page with PLC data shows Err 2 then addresses of FP7 have been used, but the protocol set in the Config Com tab is not Mewtocol7. 12.1.9 Using variable names instead of absolute PLC addresses The data type and address part TTxxxy of a PLC data display or input field can be replaced by the corresponding variable name from the FPWIN Pro project, e.g. {'VarName'_aa_bb}. Global DUTs and arrays can be addressed (not case-sensitive) in the HTML pages, too.
HTTP server functions/web pages The same mechanism can be used for .XML and .JS files, too. Carry out the following steps in FPWIN Pro to export the global variable list as a CSV file: Generating a CSV File Procedure 1. Use the menu items Project Export Variables as CSV file Global variables... 2. Select the folder where the Configurator project is stored Please choose CSV Global Variable List files (Multibyte) (*.csv) as the file type. 96 FP Web-Server V.2.
HTTP server functions/web pages 3. Save the CSV file by clicking on [Export] These steps have generated a CSV file in the Configurator project folder If a text editor is used the contents of the CSV file looks like this: Accessing a CSV file via an HTML page Procedure 1. If a Configurator project also has a FPWIN Pro CSV file, the PLC addresses in a HTML page can be referenced by its (global) variable name FP Web-Server V.2.
HTTP server functions/web pages In the HTML editor the use of these variable names instead of absolute address values can look as follows: 2. If this HTML page is now downloaded to the FP Web-Server the variable names are replaced by the absolute PLC addresses found in the CSV file Looking at the example above, with the browser it should look as follows: 12.1.10 Access protection for individual HTML pages With the FP Web-Server, Password (see "PLC access rights" on p.
HTTP server functions/web pages 2. Individual password: With the marker {PW_pppp} set in the HTML code, the user name specified in the base configuration and the password pppp of the new command will be asked for before displaying the data. Hence you can assign different passwords to different HTML pages. 3. IP lock security: The tag {PW_ip.ip.ip.ip} enables only the computer with the IP address ip.ip.ip.ip to display the page, hence enabling designated computers to display certain HTML pages.
HTTP server functions/web pages 12.1.11 Inputs for controlling PLC internal flags on HTML pages To control PLC internal flags via HTML pages, hyperlinks, as described under calling parameters (see p. 83), are used. In the example projects, you can find "links" for control in the DT200.HTM and MENT.HTM pages: Alternatively, you can use HTML input fields and HTML buttons (see "Defining input fields for PLC data on HTML pages" on p. 100) to control PLC internal flags. 12.1.
HTTP server functions/web pages It is also possible to use a PLC display field to obtain an editable pre-allocation of the input field. This has to be interpreted as follows: VALUE="{DT205_6_+d}" DT205 is read out of the PLC and interpreted as a signed decimal number and displayed in the input field with the algebraic sign. After that, the input editor is started in the HTML page.
HTTP server functions/web pages In general, there are three ways of defining an input field: A) Send input with button: Several input fields can be summed up in one 'input field' and sent to the PLC with a separately defined button. A confirmation dialog box (OK or ERROR) is generated. In the following HTML code, the current value of DT204 is written into the first input field before and after the input editor is started.
HTTP server functions/web pages Individual HTML commands can be entered (exactly as described above) into the HTML code of the page and then adjusted respectively. Some HTML editors provide additional help and automatic generation for creating submit fields. The commands have the following significance: ACTION="/plcpost" Enter precisely like this. CGI function of the FP Web-Server. METHOD="POST" Enter precisely like this. Method of the CGI call. TARGET="SUBWIN" Enter precisely like this.

HTTP server functions/web pages Further examples: More PLC data entry examples can be found in "Example - Web pages and e-mail". 12.1.12.2 Notes on strings Note FP Web-Server V.2.8 The format definition S is used for ASCII strings without "header", i.e. an ASCII string is generated with the F95 command in the PLC. The length that was determined in the input field definition is the maximum string length that can be transferred to the PLC.
HTTP server functions/web pages 12.1.12.3 Comments on defining input fields for PLC data on HTML In the current version, DT, FL, LD values as well as R and Y can be defined in input fields. In the definition of the input field NAME="DT205_6_d", only numbers from 0 to 9, letters from A to Z and the underscore are permitted! Do not use special characters like * - < > $ % / ' & and so on! To send Boolean values from the type R and Y, use this syntax: NAME="R123_100_u".
HTTP server functions/web pages 12.1.12.4 Extended Http POST functions Additionally to processing input fields for HTML data on HTML pages (see "Data fields for displaying PLC data on HTML pages" on p. 87) some helpful functions are implemented. In the standard definition each PLC data value is defined by a special data tag “{dd_x_y_z_f}”.
