Testing the function of the fieldbus node

1. To test the communication with the coupler and the correct assignment of
2. Enter the command: "ping" with the IP address you have assigned in the

3. When the Return key has been pressed, your PC will receive a response from
the coupler, which will then be displayed in the DOS prompt.
If the error message: "Timeout" appears instead, please compare your entries
again to the allocated IP address.
4. When the test has been performed successfully, you can close the DOS
prompt.
The network node has now been prepared for communication.
3.1.6.6

Deactivating the BootP Protocol

By default, the BootP protocol is activated in the coupler.
When the BootP protocol is activated, the coupler expects the permanent
presence of a BootP server. If, however, there is no BootP server available
at a power-on reset, the network remains inactive.
To operate the coupler 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 coupler.
1. Disabling of the BootP protocol is done via the built-in web pages stored in
