Summary The following list summarizes the steps to configure the 1756-RIO module in
adapter mode.
1. Set the baud rate.
2. Autoconfigure online racks on the network. (Make sure the controller is
set to Program Mode.)
3. Set the communication path.
4. Manually add any additional racks that are not online.
5. Manually add and configure block transfer modules.
6. Map/Automap the data.

IMPORTANT
Configuring the 1756-RIO module as an adapter enables the RIO
module to emulate a 1771-ASB module. This allows a path for
peer-to-peer data to be exchanged between the scanner
controller and the ControlLogix owner of the RIO module over
the Remote I/O network. The adapter mode functionality does
not allow the scanner controller to directly control any 1756-I/O
in the chassis with the RIO module.
