DEFAULT GATEWAY
The Default Gateway address sets the default route to remote networks, enabling users to access the Modbus
gateway from outside the local network.
DHCP
DHCP (Dynamic Host Configuration Protocol) is a protocol used on special servers that supply IP addresses to
network nodes on request.
When DHCP is enabled on the Modbus gateway (factory default), on power up it sends a DHCP request to the
DHCP server, which assigns a dynamic IP address, subnet mask, and default server to the Modbus gateway.
When DHCP is disabled (static IP addressing), the IP Address, Subnet and Default Gateway fields must be set
manually by entering the appropriate addresses in these fields. If you do not know what addresses to use in these
fields, ask your network administrator.
Notes:
A dynamic address assigned by the DHCP server may change if the server loses the Ethernet
connection or power is removed. If a device on the network that normally communicates with the
Modbus gateway is configured to communicate with a specific IP address of the Modbus gateway,
and the IP address has been changed, the device will not be able to communicate with the Modbus
gateway. Therefore, disabling DHCP and using a static IP address is recommended. If a DHCP
server is not found on the network, the Modbus gateway automatically configures to IP address
169.254.102.39
FIRMWARE VERSION
The Firmware Version number (Vx.x.x) indicates the Modbus gateway's currently loaded firmware release. From
time to time new firmware is made available and can be uploaded into the Modbus gateway using the Ethernet
Modbus Gateway Manager.
HARDWARE VERSION
The Hardware Version number of the Modbus gateway hardware is displayed on the Login page of the Ethernet
Modbus Gateway Manager.
ID ROUTING
ID routing allows the gateway to manage slave device IDs between various Modbus interfaces. By filling in the user
defined slave ID table, a Modbus Gateway routes requests to the correct serial port. One connection can command
serial slaves on multiple serial ports.
