HTML page on the BX9000
For diagnostic purposes you can create a simple HTML page on the BX9000. The page can be used for displaying strings from the PLC. If the page active, it can be displayed by entering the IP address in a web browser.
 | Displaying your individual HTML page In delivery state a general HTML interface is stored on the BX9000. This must be disabled, in order to display your individual HTML page. This is dealt with by the HTTP function block. When it is called for the first time it deactivates the default page and reports "bRebootNecessary:=TRUE". This means that the coupler has to be restarted. After a BX9000 restart you can call up your individual HTML page. |
HTTP
A rising edge of bActive activates the web page. If the HTML page is available the bit bIsActive is TRUE.
