Install Your ArmorBlock
I/O Module
To install the module:
•Set the node address
•Mount the module
•Connect the cord sets
•Attach the network cables
•Communicate with the module
Set the Node Address
Valid node addresses are 00 through 63.
Set the node address using either the rotary switches, RSNetWorx for
DeviceNet, DeviceNetManager, or another software configuration
tool. Setting the switches at any number from 64 to 99 lets the
software have address control.
Each module is shipped set for node address 63. Remove the caps on
the front of the module to access the switches. The two switches are:
•X10 (most significant digit) - left side of module
•X1 (least significant digit) - right side of module
To reset the node address, use a small blade screwdriver to rotate the
switches. Line up the small black dot on the switch with the number
setting you wish to use and then cycle power.
ATTENTION Preventing Electrostatic Discharge
This equipment is sensitive to electrostatic discharge,
which can cause internal damage and affect normal
operation. Follow these guidelines when you handle
this equipment:
•Touch a grounded object to discharge potential
static.
•Wear an approved grounding wriststrap.
•Do not touch connectors or pins on component
boards.
•Do not touch circuit components inside the
equipment.
•If available, use a static-safe workstation.
•When not in use, store the equipment in
appropriate static-safe packaging.

The rotary switches are read periodically. If the switches have been
changed since the last time they were read and they no longer match
the on line address, a minor fault will occur, which is indicated by a
flashing red MOD LED. Settings between 64 and 99 cause the module
to use the last valid node address stored internally. Example: The last
setting internally was 40. If a change is made to 68, and then you
power up, the address will default to 40.
The module is equipped with AutoBaud detect. AutoBaud lets the
module read the settings already in use on your DeviceNet network
and automatically adjusts to follow those settings.
Set Node Address
This example shows the default
node address set at 63. 31433-M

Pinout diagrams for the I/O connectors are shown below.
The self-configuring modules (1732D-8CFGM8 and 1732D-8CFGM12)
contain both input and output functionality.
If an I/O point is to be an output, dedicate that point as an output
with a wired load and energize it through a control program.
Energized outputs will show an associated active input, which can be
used as a feedback mechanism to ensure that the output is turned on.
If an I/O point is to be an input, wire the input device as normal and
leave the associated output un-energized at all times.

Attach DeviceNet Cables
Attach the 5-pin (12mm) DeviceNet style connectors as shown below.
To terminate the module, use the second DeviceNet connector and a
Rockwell Automation terminator resistor (Cat. No. 1485A-T1D5).
Attach Auxiliary
Power Cable
Attach the 4-pin (12mm) style connector as shown below.
Input and output devices are powered through the module’s I/O
connectors. Removing auxiliary power will deactivate all sensors and
actuators unless they are powered from a separate source. If a
separate source is used, devices may still be active, even if auxiliary
power is removed. To ensure that auxiliary power controls the
activation/deactivation of sensors and actuators, always wire input
sensors and output actuators directly to the I/O connectors.
Communicate With Your
ArmorBlock I/O Module
This ArmorBlock module’s I/O is exchanged with the master through
a poll, change-of-state, or cyclic connection.
Cyclic - allows configuration of the block as an I/O client. The block
will produce and consume its I/O cyclically at the rate configured.
Polled - a master initiates communication by sending its polled I/O
message to the module. The module consumes the message, updates
outputs, and produces a response. The response has input data.

Change-of-State - productions occur when an input changes or a
fault condition occurs. If no input or fault condition change occurs
within the expected packet rate, a heartbeat production occurs. This
heartbeat production tells the scanner module that the I/O module is
alive and ready to communicate. Consumption occurs when data
changes and the master produces new output data to the I/O block.
1732D-8CFGM8 and 1732D-8CFGM12
Note that the 1732D-8CFGM8 and 1732D-8CFGM12 self-assigning
modules contain both input and output functionality. These modules
do not need to be configured.
If an I/O point is to be an output, dedicate that point as an output
with a wired load and energize it through a control program.
If an I/O point is to be an input, wire the input device as normal and
leave the associated output un-energized at all times.
