5-2 Setting Up a DH+ to RIO Block Transfer Pass Thru Communications System
Publication 9303-5.13 – March 1998
To communicate with a drive over RIO, you need to set the drive’s RIO adapter
up so that it appears to be an adapter to a PLC RIO scanner. To do this, you need
to specify the rack and group number where the drive is to appear on the RIO
network. You will do this during the Connecting to the Drive step. You should
refer to the documentation for your drive and the communications module for
information on configuring the drive as an RIO device.
Figure 5.1 shows an example of a DH+ to RIO Block Transfer Pass Thru
communications system.

DH+ to RIO Block Transfer Pass Thru Network
Important: RIO Block Transfer Pass Thru communications to drives take
approximately 2 seconds per point, and the PLC acting as the gateway must not
use any Block Transfer instructions addressed to the drive in its ladder logic
program.
Important: DriveMonitor32 and DriveBlockEditor32 cannot be used with RIO
Block Transfer Pass Thru communications systems.
Important: For RIO Block Transfer Pass Thru communications to work, the
PLC to which the drive is connected must be in RUN mode. If the PLC is not in
RUN mode, pass thru messages cannot be delivered to the connected drive
product.
