Initialization Mode Selection
Bootp & Store
When Bootp & Store is selected, the parameters obtained from a Bootp
Server become the active parameters immediately. In addition, they are
stored to the non- volatile memory of the module. Thus, after a power
cycle they are still available. This enables a kind of bootp once
configuration of the module.
Example: The user may not want to have a Bootp Server be active in his
network all the time. But on the other side, he may not have any other
configuration method than Bootp. In this case he starts the Bootp Server
temporarily, powers on the module using the initialization mode
Bootp & Store, waits for the Bootp cycle to be completed, closes the Bootp
Server and powers off the module. Then he selects the initialization mode
Using Stored and powers on the module again. From now on, he is able to
establish the TCP/IP connection to the module with the parameters
obtained in that single Bootp cycle.

Use the initialization mode Bootp & Store carefully, because writing to the non-volatile
memory takes time. Therefore, when the module shall obtain its parameters from a Bootp
Server every time it is powered on, the recommended initialization mode is Bootp!
