3 Welcome to HTML Code Generator! Introduction: Welcome to the HTML Code Generator (HCG) and Applet generation Utility V 1.0 for the Simatic IT Modules: CP IT, CP IT, CP IT. With this program, any user can generate web pages quickly and effectively for the Simatic IT Module family. The focus is on the use of the S7 Applets, which are part of the CP file system. We have up to 4 possible applets and multiple combinations of them. The 4 main applets are the S7 Get (get data from PLC), S7 Put (write/put data to PLC), S7 Ident (Identification), and S7 Status (Status of module in rack). For the most part, the generation process creates the HTML and applet code automatically. But, if necessary, you can refer to the manual for the IT CP s to make code changes or find further information which is located on Siemens customer support website at: You can also use this program to change the HTML Code to build your own web pages and use the utility as a helpful tool to learn about the applets. Software Requirements Operating Systems tested: Windows 98SE, NT, 2000 and XP. Internet Explorer (4.02 or higher) tested Sp1. Microsoft Java VM or Sun Java (1.4.1 or higher) The Microsoft Java VM is no longer downloadable on Microsoft s website, but can be obtained through many 3 rd party sites by searching on the web. Latest File system for IT Cp s, which can be downloaded from: //200 file system //300 file system //400 file system This program requires Internet Explorer version 4.02 or higher. V SP1 or greater is recommended! Hardware Requirements Cp IT or Cp IT or Cp IT with latest firmware (latest firmware available on customer support website.) It might be necessary to reformat the file system of the IT CP. Read the firmware instructions carefully for this information) Valid Ethernet Network/Cabling arrangement between PC and CP PC w/ Software requirements above Comments or suggestions on the HTML Code Generator can be submitted to the hotline address: Simatic.Hotline@sea.siemens.com with ATTN: HTML Code Generator in the subject line. We can t make any promises that we will be able to grant all requests or follow up on all comments, but will try our best! All ideas for the HTML code generator will become SE&A property. 3

4 Current Features: Generation of HTML and Applet code for the 200/300/400 IT Module family CP IT, CP IT, CP IT using the built in applets S7 Get, S7 Put, S7 Ident and S7 Status. Note: Ident and Status are not currently supported by the Cp 243-1! You can use the built-in Ident and Status page on the S7 200 if necessary. Applets can be adjusted to support almost all of the different features such as applet color, data areas, data types, symbolic access, graphical display, and multi-read with S7- Get. Note: The generator cannot currently create a multi-variable Put. Generated Pages can be printed directly to the printer and/or saved to local files. Generated Pages can also be saved directly to the IT Modules via the built in FTP functionality and be displayed automatically by Internet Explorer using a hotkey (hit Shift key while pressing the Transfer button). If selected, the utility can create a HTML page structure with a main index page and subindex for all of the applets created in the HTML Code Generation sessions. Warning! If you select to use the Index feature, be forewarned that this will overwrite the existing index page! An example of using the index / sub-index feature is located on the last page of the manual. This should not be a problem, because the links to the standard page can still be used by selecting your IT Cp version from the menu bar, on the HCG index page. (200,300, or 400). See last page for example. The file system can always be restored if necessary. If you have files on the CP which you don t want to be overwritten, please back up all files beforehand. See the information above in the software requirements section. This manual covers the different screens and functions of the HTML Code Generator program and explains how to use them. Features Coming Soon! Multi-put New Applets w/ selectable graphic display support! IT File System Restore Utility embedded. 4

5 The Main Setting Screen Let s first get started by looking at the main screen. Tip: If you hold your mouse over the different fields in the program, help text will automatically be displayed! HTML Page Title Please enter the HTML Page title (displayed in the Browser Title). Tip: If you have the index option checked, the HTML Page title is automatically added to the sub-index column on the index page. CPU Type Select the CPU Type you are working with. S7 200 or 300/400. Rack Number Select the Rack number in which your CPU is located. (Normally 0 unless CPU is in an expansion rack) CPU Slot Number Select the CPU Slot number in which your CPU is located. Tip: Make sure you don t use the CP slot here because the applets will not work! Language Please select English or German. Background Color Please select the color of your applets / page with this setting. You can choose to use default colors or select your own with the User Defined Option. If you opt to select your own color, another screen will appear and allow you to customize it. Using the R (Red), G(Green) and B(Blue) selectors, please change the output window to the desired color and hit the OK button to continue. 5

6 Warning! The applets use a font, which is usually black. Using dark colors and shades may make the display unreadable. Create Index If checked, will automatically create a master index (Navigation) file on the CP, which will contain all generated pages (when checked). Pages must be given different names in order to be added to the sub-index, which is a part of the master index page. If you use the same name for a file, then the page with the same name will be overwritten and updated in the index. Warning! If you select to use the Index feature, be forewarned that this will overwrite the existing index page! If necessary, the file system can be restored with the factory file system settings as discussed in the requirements section. See the last page of the manual for an example of using the index feature. The S7 300/400/200 file system is also located on the manual CD supplied with the product(s). Create selected S7 Applets This selection allows the user to select which applets to display on the HTML page. You can do many combinations of applets per page with this feature. (See picture below for example, notice the highlighted checkboxes.) Warning! If create selected S7 Applets is checked and no selection is made, the page will be blank 6

Transfer File After entering the proper Address, user name, password, and filename (case sensitive!) Press the transfer file button to attempt and store the pages to the IT Module. Tip: If you press the Shift key when hitting the transfer button, the page will automatically open in Internet Explorer upon the completion of a successful download. Cancel Exit this screen and cancel FTP download All Files All files should really only be selected one time and then disabled again. This feature stores all of the HCG (HTML Code Generator) files, graphics, etc to the module and only needs to be done once because it takes some time. Save Password If you opt to save your password to the local file settings then select this option. See warning above. 17

18 HCG Index-Page Example To better understand how the index works please follow this procedure initially. This example assumes the IT CP is already configured and on the Ethernet segment. Example for the first program run when saving files directly to the IT CP from HCG using the index feature: Open the HCG Program. Select CPU Type and Rack / Slot. Check the create index checkbox. Press the Generate Button. Click Save to IT CP. Fill in proper parameters (ip, username, password) and then check all files (this is all the support files for the web page display and only needs to be done once). Type in test.htm for the filename. Click Transfer while holding the Shift Key. Acknowledge the Transfer Successful Box. Now you should have your first page displayed if everything worked correctly! Clicking the link on the left should display the test.htm page. On the next run through, you will want to change some of the applet parameters (Variable Name, Applet Name), try another bit, etc. Then generate again and when you save to the IT Cp, change your HTML filename from test.htm to test2.htm and be sure to uncheck the All Files button. This only needs to be checked the first time you download to the CP for all the HCG web page support files (and can cause the download to be very slow). The create index checkbox should always stay checked when you want to keep adding pages to the sub-index. Now when you enter the page, you should have two links in the sub index on the left. The first link should point to your test.htm page, and the second to test2.htm.--> Also note that on the upper right you can access the previous file system index page by selecting 200,300, or 400 depending on the CP in use. Congratulations! You have just created your first successful index / subindex pages with HCG! 18
