...You Build the I/O Configuration in this Order
1. Add the local communication module for
the local controller. Remember, the
1769-L35CR does not require that you add
a local communication module.
2. Add the remote communication module for
the remote controller. The communication
format for the remote module should be
None.
3. Add the remote controller.
If the remote controller is added, you can
browse to it as a destination when you
configure the message instruction.
Publication CNET-UM001C-EN-P - November 2005
To send or receive data from a ControlNet module via a message, you must
program a MSG instruction in the local controller's logic. If the target module
is configured in the I/O Configuration folder of the controller, you can
browse to select the module. Otherwise, you can manually enter the message
path in the MSG instruction.
Add the ControlNet Modules and Remote Devices to the Local
Controller's I/O Configuration
Use Browse to select the target device of a MSG instruction and add that
remote device to the I/O Configuration folder of the local controller. Within
the I/O Configuration folder, you organize the local and remote devices into a
hierarchy (tree/branch, parent/child).
