Atop Modbus Gateway
MB5400 Series
User’s Manual V 1.3

Dual Subnet Mode:
Two Ethernet ports have separate IP addresses and subnets
Redundancy Mode:
The system will use only one port for data transfer. If the port
is disconnected, the whole system will change to another port automatically.
3.6 Network Configuration
In this section, IP address, Subnet Mask, Default (Network) Gateway, Domain Name System
(DNS) and overall connectivity settings can be accessed as shown in Fig. 3.8. For any LAN
Settings, you can check the
DHCP
box to obtain an IP address, Subnet Mask, and Default
(Network) Gateway automatically. When operating in
Redundancy Mode,
the Modbus
Gateway device will have the two LAN ports connected
1
to the network, but the signal will flow
through only one of them. If one port is out due to any reason, there will still be another route
for the signal to keep on flowing.
Note
1
:
You can connect only one LAN port to the Modbus Gateway device and change the settings on this page.
However, the
redundancy
function will no longer work.
