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

Beckhoff BootP server

Beckhoff supply a BootP server for Windows 98, ME, NT4.0, NT2000 and XP. The installation version can be found on the Beckhoff TwinCAT CD in folder Unsupported Utilities or under 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 allocation MAC ID for IP address takes place via 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).
