Now it is important to restart the coupler by resetting the hardware . This en-
sures that the new IP address will be accepted by the coupler.
To do this, cycle power to the fieldbus coupler for approx. 2 seconds.
Following this, the IP address in the coupler is permanently stored and
maintained even once the coupler is removed or following a longer voltage
failure.

Subsequently, click on the "Stop" button and then on the "Exit" button, to

Testing the function of the fieldbus node
1.
To test the communication with the coupler and the correct assignment of
the IP address call up the DOS prompt under Start menu / Program / MS-
DOS Prompt.
2.
Enter the command: "ping" with the IP address you have assigned in the
following form:
ping [space] XXXX . XXXX . XXXX . XXXX (=IP address).
Example: ping 10.1.254.202

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.
