In the Communications View and Setup Start screens, you can set up the Ethernet communications parameters for
the System 450 control module. You must use a web browser on a computer that is connected to the control
module.
Refer to the System 450 Series Modular Control Systems with Communications Control Modules Technical Bulletin
(LIT-12011826) for more information and procedures for setting up a System 450 control module with Ethernet
communications.
Table 11 provides procedures, screen examples, and general information for setting up a System 450 control
module with communications on an Ethernet network.
You can use an Ethernet patch cable to connect your computer or laptop directly to the System 450 control module
with Ethernet communications.
The default (factory set) Ethernet IP address for a System 450 control module with Ethernet communications is
169.254.1.1.
Edit Sensor Selection Screen: This screen displays the sensor that this output currently references.
Typically, no action is taken in this screen. But if you need to change the sensor that this output
references, you can select a different sensor for this output in this screen.
Note: If you change the sensor that an output references to a sensor with a different Sensor Type, the
default setup values for the output change, and you must set up the output again.
11. If you are not changing this output’s sensor, simply press to save the current sensor selection and
return to the Analog Output Setup Start screen.
To change the sensor this output references, press or to select the new sensor that this output
references. Then press to save the new sensor selection and return to the Setpoint Selection
screen (SP or dSP). If the new sensor has a different Sensor Type from the previously referenced
sensor, repeat the output setup procedure for this output.
The screen example shows Sn-2 as the selected Sensor for Output 3.
Analog Output Setup Start Screen:
After you have set up this analog output, you can go to another Output Setup Start screen, the Sensor
Setup Start screen, or return to the Main screens.
12. Press to scroll through the remaining Output Setup Start screens and return to the Sensor Setup
Start screen, or press and simultaneously to return to the System 450 Main screens.
The screen example shows the Analog Output Setup Start screen for Output 3.
