b. The default network configuration is to receive an IP address assignment from
a DHCP server. DHCP controls whether or not a DHCP server is used to set
the IP address, subnet mask and default gateway of the Modbus Gateway.
When DHCP option is enabled but the DHCP server is not found, the Modbus
Gateway will automatically configure IP address 169.254.102.39 with a
subnet mask 255.255.0.0
c. To configure your Modbus Gateway without using a DHCP Server, uncheck the
“I want DHCP to setup the network” box. You will need to know the IP
Address, Subnet Mask, and Default Gateway.
IP Address field contains static internet protocol address of the Modbus
Gateway.
Subnet Mask field contains mask that is used to define sub network.
For Class A network (IP addresses 0.0.0.0 through 127.255.255.255), the
default subnet mask is 255.0.0.0.
For Class B network (IP addresses 128.0.0.0 through 191.255.255.255), the
default subnet mask is 255.255.0.0.
