See the table below to configure the subnet mask and gateway
address fields for each processor via your programming software.
Configure Subnet Task and Gateway Field
This field Specifies Configure by doing the following
Subnet Mask The processor’s subnet mask.
The subnet mask is used to interpret IP
addresses when the internet is divided
into subnets.
Enter an address of the following form:
a.b.c.d Where: a, b, c, d are between 0...255 (decimal)
If your network is not divided into subnets, then leave the subnet mask
field at the default. If you change the default and need to reset it, type
0.0.0.0.
Gateway Address The IP address of the gateway that
provides a connection to another IP
network.
This field is required when you
communicate with other devices not on a
local subnet.
Enter an address of the following form:
a.b.c.d Where: a, b, c, d are between 0...255 (decimal)
The default address is No Gateway.
