Configure The Communication Modules - Allen-Bradley AB QUALITY ControlLogix 1756 Series User Manual

An IP Address is an Ethernet node's
network address and denotes the network
where the 1756-ENET module is located.
Before you begin, check the IP
address. Make sure your entry is in the
form xxx.xxx.xxx.yyy, where each xxx is a
number between 0-255 and yyy is a
number between 0-254.
A Subnet Mask identifies the bits of the
internet address that correspond to the
network and subnetwork portions of the
address. Before you begin, retrieve your
subnet mask. Make sure your entry is in
the form xxx.xxx.xxx.yyy, where each xxx
is a number between 0-255 and yyy is a
number between 0-254.
A gateway is a shared connection
between two networks. It consists of
hardware and software which provides
protocol conversions. An Ethernet
Gateway Address is the IP address of the
Ethernet gateway you want the
1756-ENET module to use. Before you
begin, retrieve your Ethernet gateway
address, if you are using one. Make sure
your entry is in the form xxx.xxx.xxx. yyy,
where each xxx is a number between
0-255 and yyy is a number between
0-254.
Bootp (Bootstrap protocol) is used to boot
diskless nodes, such as 1756-ENET. The
Bootp server supplies the IP address,
subnet mask, and Ethernet gateway. In
this example you are providing the IP
address, so make sure Bootp is not
enabled.
