Remote Web Access
To access the user interface for Wi-Fi Administration through the field area network,
set the
Remote Web Access
setpoint to “on.”
Note:
The
Remote Web Access
setpoint is not available until the default admin
password is changed and remote access requires the field area network to be routed
through the Wi-Fi/GPS Unit. Refer to the “Configuration” section on page 21 for more
details.
The
Remote Web Access
toggle button enables Web-user interface access via
Ethernet Port 2. This configuration setting can only be updated by the admin user, and
only after the admin user has changed the default password. Web access via Ethernet
Port 2 is also controlled by a DNP3 binary output setpoint, which must also be enabled
to allow this traffic. See Figure 15.
NOTICE
When a SpeedNet™ Radio is used for the field area network radio, the remote
Web user’s computer will require an additional setting to be updated to enable
Web access . The user must reduce the MTU (maximum transmission unit) size to
a value of 500 or lower . S&C recommends using an MTU size of 500 for optimal
performance . To change the MTU size, the following command can be used on
a Windows 10 machine:
netsh interface ipv4 set subinterface “Local Area
Connection” mtu=500 store=persistent
.
