Wi-Fi Administration
Interfaces
Ethernet 1 (To Control Module)
In this panel, the network associated with the Wi-Fi/GPS Unit local area network (LAN)
is defined for devices connecting to physical Ethernet Port 1. See Figure 11. The S&C
Wi-Fi/GPS Unit ships with a default IP address of 192.168.1.1 and a Netmask equal to
255.255.255.0.
Ethernet 2 (WAN)
This panel defines the IP addressing for the Wi-Fi/GPS Unit’s Ethernet Port 2 and
subsequent network linkage and settings respective to the customer’s legacy backhaul
WAN network. The default setting is
DHCP Enabled
. See Figure 11.
Note:
The use of these fields is for WANs that use Ethernet as a back-haul transport
protocol. When serial back-haul networks are used or there is no WAN, this panel will
not require entries.
DHCP Client State “On”
No fields require identification. A DHCP request will be initiated by the communication
gateway to the WAN’s DHCP server, which will assign an IP address for all data
communication over the WAN.
DHCP Client State “Off”
Three fields require identification:
Static IP Address
,
Default Gateway IP Address
,
and
Netmask
. The
Static IP Address
setpoint is the WAN IP address assigned to the
Wi-Fi/GPS Unit. The
Default Gateway IP Address
setpoint is the address of the network
device up-stream of the Wi-Fi/GPS Unit and determines the destination of DNP3 traffic
sent to the SCADA master(s). See Figure 12 on page 15.
The address entries are automatically verified to be sure they function with the other
values entered.
