Using the Channel 0 Default Communication Push Button
The Channel 0 default communication
push button is located on the front of the
controller in the lower right corner as
shown in the illustration.
Use the Channel 0 default
com
munication 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
co
mmunication configuration for Channel 0. Pushing the default communication push
button resets all configured parameters back 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.
