7.12 NETMASKS (NETMASKS)
It sets the network number and subnet mask when connection is established with another
network.
The subnet mask indicate a range the network number portion represents in the IP address
(“xxx.xxx.xxx.xxx” where “xxx” denotes 0 to 255).
■
Format
Network netmask
“ ” denotes a space.
●
Network (network number)
It sets a network number of the network to which the CR-IR341 is connected.
●
netmask (subnet mask)
It specifies a range the network number portion represents in the IP address.
It is set in the form of “xxx.xxx.xxx.xxx” (where “xxx denotes a decimal numeral ranging from
0 to 255), and the bit of the portion handled as the network number is set to “1”, while the bit
of the portion handled as the host number is set to “0”.
It is classified into the following network classes according to the range of the network
number portion.
Class A 255.0.0.0
Class B 255.255.0.0
Class C 255.255.255.0
The narrower the range of the network number portion, the greater portion may be handled
as the host number (the greater for classes C, B, and A in this order). Thus, more host
addresses (IP addresses) may be assigned within the same network (that is, a larger
network may be implemented).
◆
NOTE
◆
If the networks for the CPU90E and CPU90F are the same, the same net mask should be
set for both. If the CPU90F is not available, the net mask for the CPU90F is left on its
default, regardless of its setting value.
