• 1 ArmorBlock MaXum module
• these installation instructions
(Note: Cable bases are ordered and shipped separately.)
• Connect the input/output cord sets to the MaXum module
• Communicate with your ArmorBlock MaXum I/O module
Each of these steps is explained in the following procedures.
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.
Set the Node Address
Valid node addresses are 00 through 63.
Set the node address using the rotary switches, RSNetWorx for
DeviceNet, or another software configuration tools. Setting the
switches to a number from 64 through 99 lets the software have
address control.
Each module is shipped set for node address 63. The switches are
located on the underside of the module. The two switches are:
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.
The rotary switches are read at module power up only. Settings from
64 through 99 cause the module to use the last valid node address
stored internally. For example, the last setting was 40. If a change is
made to 68, and then you power up, the address will default to 40.
Refer to the following illustration of the node address.
Node Address is
set at 62; see
small black dots.

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.
Mount the Module to the Cable Ba se
This module mounts to the following cable bases:
• 1792D-CBFM for KwikLink flat media installation
• 1792D-CB12 for 12mm drop cable installation
• 1792D-CB18P for round media DeviceNet and output power

WARNING
IMPORTANT
ATTENTION
Use supply wires suitable for 30°C above
surrounding ambient.
If the devices (sensors) connected to the input
connections require Class 2 power to operate, the
DeviceNet connections of this equipment must be
powered by a Class 2 source.
• Make sure all connectors and caps are securely
tightened to properly seal the connections
against leaks and maintain IP67 requirements.
• For maximum noise immunity, input and output
cable return wires must be properly terminated.
When inputs and outputs are connected in
loopback, return wires should be connected
together.
If you connect or disconnect wiring while the
field-side power is on, an electrical arc can occur.
This could cause an explosion in hazardous
location installations. Be sure that power is
removed or the area is nonhazardous before
proceeding.
Output Power and DeviceNet Cables
Output power and DeviceNet cables are described in the installation
publications for the cable base assembly of your choice. Refer to the
following publications:
• 1792D-IN009 ArmorBlock MaXum Cable Base Installation
Instructions
• DN-6.7.2 DeviceNet Cable Planning and Installation Manual
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 12 input / 4 output module consumes
the message, updates outputs, and produces a response. The
response has input data, input faults, output faults, and the status of
the auxiliary power.
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.
