6. Click Ok to save the new settings.
Note: Clicking Ok on the Network Configuration page after changing network setup values initiates a reset of the
Ethernet control module. After the reset, the new network settings take effect and the direct connection is no longer
functional.
7. Remove the Ethernet cable from the computer and connect the Ethernet control module to the router on the
local network you specified.
8. Enable the wireless networking feature on your computer again so it can connect to the router local network.
Type the static IP address assigned to the Ethernet control module in the address bar of the web browser to
open the web UI and verify it connects to the network. You entered this IP address into the Ethernet control
module's IP address field in Step 2.

System 450 Web User Interface

System 450 control modules with Ethernet communications have an integral web server. The web server delivers
web pages to client browsers on desktop and laptop computers. The System 450 web UI allows you to monitor
your control system status and change the configuration in simple, user-friendly web pages delivered to your
computer though a direct connection, connection through a LAN, or over the Internet.
Note: You can monitor control system status and configure the control system parameters in both the local UI
(LCD and four-button touchpad) and the web UI. But you can only configure the control system's network settings
in the web UI.
See Viewing Network Settings, Setting the Remote Network UI Access Lock, and Resetting the Network Settings
on page 25 for the procedures on establishing a direct connection between a computer and the communications
control module.
Refer to the System 450 Series Modular Control Systems with Communications Control Modules Technical Bulletin
(LIT-12011826) for more detailed information on connecting to your System 450 communications control system to
a local network and the Internet.

System Overview Page

Figure 8 shows an example System Overview page for a System 450 control system that is set up and operating.
In the System Overview, you can view the system status, system setup parameters, and values, and you can log in
to the control system's web UI.
Note: You cannot make any changes to the system configurations on the System Overview page. You must log in
to the web UI with the assigned username and password and then go to the sensor and output configuration pages
to change your control system parameters and values.
This control system example uses the following input sensors and outputs:
• a pressure sensor (Sn-1) to control the motor speed of two condenser fans with analog outputs (OUTA1 and
OUTA2)
• a temperature sensor (Sn-2) to control the cooling equipment (using Relay Output OUTR3) that maintains
room temperature
• a humidity sensor (Sn-3) to control the humidification equipment (using Relay Output OUTR4) to maintain the
room humidity
