Use the Channel 0 Default Communication Push Button
The Channel 0 default communication push
button is on the front of the controller in the
lower right corner as shown in the illustration.
Use the Channel 0 default communication
push button to change from the user-defined
communication configuration to the default
communication mode. The Channel 0 default
communication (DCH0) status indicator turns
on (green, steady) to indicate that the default
communication configuration is active.
TIP
The default communication push button is recessed.
Before pressing the default communication push button, be sure to note the
present communication configuration for Channel 0. Pushing the default
communication push button resets all configured parameters to their
default settings.
To return the channel to its user-configured parameters, you must enter
them manually while online with the controller or download them as part of
an RSLogix 5000 software project file. To do this online with RSLogix 5000
software, access the Controller Properties dialog and enter parameters on
the Serial Port, System Protocol, and User Protocol tabs.
