I/O Board Option
(20-XCOMM-IO-OPT1) The I/O Board option, when installed in the DPI External Comms Kit, can
be used with only a Series B adapter, firmware revision 3.xxx or later. The
I/O Board provides six DC inputs and two Relay outputs for use by a
controller on the network.

For more information, see the I/O Board Option Installation Instructions,
publication 20COMM-IN002.
Understanding the I/O Image
(Drive + I/O Option) The data for the optional I/O Board is sent over the I/O connection using
Datalink D. When the optional I/O Board is installed in the DPI External
Comms Kit, Datalink D is dedicated only for this function and is not
available for other uses. When the adapter detects the presence of the
optional I/O Board, the I/O image is modified as shown in
Figure 8.3 .
