ControlNet I/O Connection
A ControlNet Class 1 connection sets up the ControlNet scanner in a Logix
controller to read implicitly the ScheduledData.Input instance and control
outputs without the use of message instructions in logic. The ControlNet
connection excludes the power monitor configuration. You can use a web
browser, FactoryTalk EnergyMetrix RealTime (RT) software, or other means for
power monitor setup. If a ControlNet connection is active, you are not permitted
to change the Configuration.OptionalComm.CNT setup or execute output
forcing commands.
It is not necessary to establish an I/O connection to allow explicit messaging with
a ControlNet PowerMonitor 5000 unit that is connected on a ControlNet
network.
Follow these steps to configure a ControlNet I/O connection by using the Logix
Designer application and RSNetWorx for ControlNet software.
1. Launch the Logix Designer application.
2. Open the project file for your controller in offline mode.
3. Expand the I/O tree and choose the ControlNet network.
4. Right-click the ControlNet item and choose New Module.
5. Select the Generic ControlNet Module CONTROLNET-MODULE
from the list of Communication modules and then click Create.
