Setting the IP-address via the Beckhoff BootP-server

Rotary switch in position 0xF2

The address assigned by the BootP server is stored, and the BootP service will not be restarted after the next cold start.

The address can be deleted by switching to manufacturer setting with the KS2000 or via the rotary switch (0xFF). 

Rotary switch in position 0xF1

The IP address assigned by the BootP server is only valid until the module is switched off. At the next cold start, the BootP server must assign a new IP address to the module.
The address is, however, retained through a software reset of the module.

Beckhoff BootP server

Beckhoff supplies a BootP server for Windows 98, ME, NT4.0, NT2000 and XP.
You find the installation version on the Beckhoff TwinCAT CD in folder Unsupported Utilities or from http://download.beckhoff.com/download/Software/TwinCAT/TwinCAT2/Unsupported Utilities/TcBootP Server.

As soon as the BootP server has started, the New MAC Address window shows all the Beckhoff nodes that are working in BootP mode and still have not received an IP address. The assignment of the MAC-ID to IP address is made with the "<<" button. Successful assignment is displayed in the log window.
To start the BootP server automatically when your PC boots, it is only necessary to provide a shortcut in the Windows autostart folder. Include the /Start parameter in the shortcut (.../TcBootPDlg.exe/start).
