Related Terms
This manual uses the following terms:
Term: Definition:
Adapter POINT I/O DeviceNet adapter (1734-ADN and 1734-ADNX).
Auto Catalog Replace The POINT I/O DeviceNet adapter supports the swapping of
two identical modules connected to the adapter. I.e., if a
1734-IB4 is in slot 3 and another 1734-IB4 is in slot 7, the two
modules can be removed from the POINT system and the slot 3
module placed into slot 7, and vice-versa. When ADR is active,
the swapped modules will be reconfigured to match the
previous module in their new slot. When ADR is not active, the
configuration parameters will not be modified, the swapped
modules must have identical configuration, and values for
their EDS file parameters.
Auto Device Replace This refers to the ADR feature of a ControlLogix System on
DeviceNet. With ADR active, any device on the DeviceNet link
may be removed and replaced with an out-of-the-box
checkmark compliant DeviceNet device. The ADR feature will
result in downloading the values of the configuration
parameters of the EDS file, of the removed device, to the new
device.
Auto Start Mode A feature that lets the POINT I/O system get “up and running”
without the prerequisite to configure any of the EDS
parameters for the POINTBus™or POINT I/O modules. Using
Auto Start Mode will result in a scan list within the adapter
which stores the modules identity information.
Autobaud Feature in devices (e.g. POINT I/O modules) on the DeviceNet
network that causes them to listen to communications on the
network and set their own baudrate to match the network
rate.
Backplane The PointBus that consists of POINT I/O modules connected to
the 1734-ADN(X) adapter.
Baudrate Rate of communications between devices on the DeviceNet
network. Backplane baudrate is used for the 1734-ADN.
Subnet baudrate is used for the 1734-ADNX.
Change of State (COS) DeviceNet communications method in which the adapter
sends data based on detection of any changed value within
the input data. Data is independently received based on
change of state from the sender. Data in both directions can be
acknowledged or unacknowledged depending on the run time
configuration of the system.
Commissioning The period in time associated with post startup activities.
Commissioning implies that the system has been validated
and all configuration parameters are correct, all modules are
in good operating condition, and the adapter scanlist is
complete.
ControlFlash Utility software you can use to update the adapter’s firmware
with the most current Boot and Application code.

Publication 1734-UM002C-EN-P - July 2003
Preface 4
Cyclic DeviceNet communications method in which the adapter
sends data cyclically based on a configured time value. Data is
independently received cyclically from the sender. Data in both
directions can be acknowledged or unacknowledged
depending on the run time configuration of the system.
MAC ID Media Access Control Identifier (DeviceNet network address).
Master A DeviceNet network device (e.g., 1771-SDN) that initiates
communication with DeviceNet slave devices (e.g., POINT I/O
modules) to retrieve data. The master only receives
unprompted data when the slave is enabled for COS and there
is a change in the device’s operating state.
MAX BACKPLANE ID A unique attribute, Max(imum) Backplane MACID, has
been added to 1734-ADNX. This value represents the highest
node address of a module residing on the backplane. This
value must be greater than or equal to the rightmost
backplane POINT I/O module, but must be less than that of
any non-backplane Subnet module.
Offline State of the adapter when it is not powered or maintaining
normal communications exchanges with other DeviceNet
devices.
Online State of the adapter when it is powered and maintaining
normal communications exchanges with other DeviceNet
devices.
PointBus The POINT I/O backplane. PointBus maintains all DeviceNet
network protocol but also offers configuration capabilities.
Polled DeviceNet communications method in which a module sends
data in response to received data.
Primary Network The Primary DeviceNet Network, and it is defined as the
DeviceNet link that provides the direct connection between
the POINT DeviceNet adapter and a DeviceNet scanner
RSNetWorx for DeviceNet Configuration software for the adapter and Subnet modules.
Scanlist The list of Subnet modules connected to the adapter. When
ADR is active, the scanlist stores the configured values of
each of the Subnet modules’ configurable parameters. When
ADR is not active, the scanlist stores only the module identity
information.
Scanner Operating state of the 1734-ADN(X) when it retrieves I/O data
from Subnet modules.
Slave A DeviceNet network device that cannot initiate
communication (except when configured with COS enabled)
but responds to a DeviceNet master device.
Strobe Adapter sends data in response to the strobe command. The
single bit allocated to the adapter in the strobe message is not
used. If the configured size of the input data (sent from the
adapter) is greater than 8 bytes, the strobe connection
establishment will fail. In this case, the input size must be
reconfigure to 8 bytes or less.

Guidelines for Using
Your Adapter
Remember the following operational guidelines when using your
1734-ADN(X) adapter.
Subnet 1734-ADNX only.
The Subnet DeviceNet Network, and is defined as the
DeviceNet link that provides the expansion of the POINTBus to
allow the 1734-ADNX to use its lower connector to add an
additional 500 meters and up to 63 nodes which will be
bridged through the 1734-ADNX up to the Primary Network.
Note that backplane modules are also part of the Subnet.

•Do not leave spaces in the I/O. Instead, install all POINT I/O
modules adjacent to each other.
•Populate every position on the DIN rail.
•Do not add new I/O modules to the end of the POINT I/O
system while the system is under power.
•Use both labels with the I/O modules and removable terminal
blocks (RTBs).
•Do not separate I/O modules and RTBs with the same number.
•Do not move I/O modules to different locations on the DIN rail
after they have been installed and configured. You should
always place modules with the matching RTB.
•If adjacent modules (i.e., 2 or more) are removed, replace all of
them to operate the POINT I/O system. Input data will hold last
state until all previously-removed modules are replaced.
•Use Allen-Bradley terminal markers to identify your POINT I/O
modules. The cards are easily ordered from your Rockwell
Automation representative under the Bulletin 1492 number.
For more information on the Allen-Bradley terminal marking
kits, see the documents list on page Preface-5.
Conventions Used In
This Manual

Chapter 1
Installing the 1734-ADN(X) Adapter
This chapter describes how to install and wire your adapter.
When properly installed, POINT I/O is grounded through the DIN rail
to chassis ground. We recommend using zinc plated, yellow
chromated steel DIN rail to assure proper grounding.
Other DIN rail materials (e.g. aluminum, plastic, etc.) can corrode or
oxidize and are poor conductors that may result in improper or
intermittent platform grounding.
If you choose not to use zinc plated, yellow chromated steel DIN rail
for your POINT I/O, we recommend occasional cleaning of the DIN
rail to prevent or lessen the effects of oxidation and corrosion.

4. Set the node address using the 2-position thumbwheel switch.
Valid physical settings range from 00 to 63. Press either the + or
- buttons to change the number.
You can also set the node address to some value between 64-99.
In this case, you can change the adapter’s node address via the
RSNetWorx for DeviceNet software. If a value between 64-99 is
used, at power-up the node address stored in the adapter’s
non-volatile memory is used.
5. Slide the safety end cap up to remove it. This exposes the
backplane and power interconnections.
