Starting up an ETHERNET TCP/IP fieldbus node
WAGO-I/O-SYSTEM 750
ETHERNET TCP/IP
3.1.6.6 Deactivating the BootP Protocol
By default, the BootP protocol is activated in the controller.
When the BootP protocol is activated, the controller expects the
permanent presence of a BootP server. If, however, there is no BootP server
available at a power-on reset, the PFC’s network remains inactive.
To operate the controller with the IP configuration stored in the EEPROM, the
BootP protocol must be deactivated.
Note
If the BootP protocol is disabled after the IP address assignment, the stored IP
address is retained even after power is removed from your controller.
1. Disabling of the BootP protocol is done via the built-in web pages stored in
the controller. Open a web browser on your PC (e.g., Microsoft Internet
Explorer).
2. Now enter the controller’s I/P address in the address box of the browser and
press the Enter key.
3. One of the controller’s built-in web pages is displayed. The opening page
displays information about your fieldbus controller. Click the Port
hyperlink on the left navigation bar.
4. A dialog window will open and ask for a password. This serves as access
protection, and includes the three different user groups: admin, guest and
user.
5. To logon as the administrator, enter the user name admin and the password
wago.
Note
If the controller does not display the opening HTML page, make sure your
web browser is setup to bypass the proxy server for local addresses.
