Specifying
Address
Parameters
Consult your system administrator to obtain a valid IP address and appropriate
gateway and subnet mask, if required. Then follow the instructions in
Setting
Ethernet Address Parameters
on page 325.
Assigning an IP
address Via
Concept’s “Use
IP Address”
option.
You can select the module’s “Use IP Address” mode via Concept to assign an IP
address (as well as default gateway and sub network mask) to the module.
In this mode, the module will listen for BOOTP messages at startup (but will not
issue any BOOTP requests). If a BOOTP response is received the module will use
the received IP address and the user program will be prevented from starting.
Assigning an IP
address Via
Concept’s “Use
BOOTP Server”
option
You can select the module’s “Use BOOTP Server” mode via Concept to instruct the
module to obtain its IP address from a network BOOTP server. In this mode, only
an address obtained from a BOOTP server will be accepted by the module.
To Retain
Settings
After setting the module’s address mode, you must save your program to Flash
memory if you want this setting to be retained when power is removed from the
module. This is not necessary if the module is attached to a ring adapter, which
provides battery back up. See
Saving to Flash with Concept
on page 375.
If BOOTP Server
Responds
If the server responds with address parameters, the adapter will use those
parameters as long as power remains applied to the adapter.
If the server doesn’t respond, the adapter will retry its request three times.
