The ProLinx Remote I/O (RIO) Adapter communication interface can be used to
interface Rockwell Automation Remote I/O Scanners (PLC, SLC, ControlLogix)
to other communication networks. The RIO interface, as the other solutions in the
ProLinx family, interface to the other communication networks via the module's
internal data table.

The RIO interface is an adapter (slave) and is connected to a scanner (master)
that controls the data transfer.
For example, the master/slave relationship can be accomplished using the 460X-
RIO-XXX module (adapter/slave unit) with the Rockwell Automation PLC5
(scanner/master unit). Ladder logic must be programmed into a PLC to perform
BTR/BTW commands to receive and transmit data between the module and the
PLC. The module also supports limited high speed data transfer via the Input and
Output images.
