The Channel 0 Default Communications (DCH0) status indicator turns on
(green, steady) to show when the default communication configuration is
active.
Make ControlNet Connections to the Controller
The CompactLogix 1769-L32C and 1769-L35CR controllers connect to the
ControlNet network. The CompactLogix 1769-L32C controller supports
channel A connections only. The CompactLogix 1769-L35CR controller
supports channels A and B (redundant media) connections.
For permanent connections to the network, you connect the module to the
ControlNet network by using a ControlNet tap (for example, 1786-TPR,
1786-TPS, 1786-TPYR, 1786-TPYS).
IMPORTANT
Before pressing the default communication pushbutton, be sure to note the
present communication configuration for Channel 0.
Pushing the default communication pushbutton 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 project file. To accomplish this online by using RSLogix
5000 software, enter the Controller Properties dialog box and use the Serial
Port, System Protocol, and User Protocol tabs.
