Configuring STEP 7 to use a multi-language page structure

The procedure for configuring multi-language user-defined Web pages is similar to the

general process for configuring user-defined Web pages (Page 1057). When you have

folders set up for languages, however, you set your HTML directory setting to the folder that

contains the individual language folders. You do not set the HTML directory to be one of the

language folders.

When you select the default HTML page, you navigate into the language folder and select

the HTML page that is to be the start page. When you subsequently generate blocks and

download the blocks to the CPU, the Web server displays the start page in the language

folder that you configured.

For example, if the folder structure shown here was at C:\, the set-

ting for HTML directory would be C:\html, and if English were to be

the initial page display, you would navigate to en\langswitch.html for

the default HTML page setting.

Advanced user-defined Web page control

When you generate data blocks for your user-defined Web pages, STEP 7 creates a control

DB that it uses to control display of and interaction with the user-defined pages. STEP 7 also

creates a set of fragment DBs that represent the individual pages. Under normal

circumstances, you do not need to know the structure of the control DB or how to manipulate

If you want to turn a web application on and off, for example, or manipulate individual manual

fragments, you use the control DB tags and the WWW instruction to do so.

Structure of the control DB

The control DB is an extensive data structure, and is accessible when programming your

STEP 7 user program. Only some of the control data block tags are described here.
