ArmorBlock M aXum 8 Inpu t Mo dul e with
8 Connectors, Series B

(Cat. No. 1792D-8BV0D)

42761

This ArmorBlock MaXum I/O module (Cat. No. 1792D-8BV0D) is a
stand-alone 24V dc I/O product which communicates via a
DeviceNet network. The sealed housing of this module requires no
enclosure.

This model has 8 inputs. Inputs are 24V dc automatically configured
for PNP (sourcing) or NPN (sinking) devices. Diagnostic features are
short circuit and open wire detection reported to the point level.
Local logic control has been added to this Series B product. The
1792D-8BVT0D also has 8 inputs but only 4 connectors. This new
module gives you complete single point diagnostics.

ArmorBlock MaXum 8 Input Module with 8 Connectors, Series B 3

Install Your ArmorBlock MaXum I/O Module

To install module:

• Set the node address

• Mount the module to the cable base

• Connect the cord sets

• Communicate with the module

Set the Node Address

Valid node addresses are 00 to 63.
Set the node address using the rotary switches, RSNetWorx for

DeviceNet, DeviceNetManager, or other software configuration
tool. Setting the switches between 64 to 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:

• MSD (most significant digit)

• LSD (least significant digit)

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
between 64 and 99 cause the module to use the last valid node
address stored internally. Example: The last setting 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.

Install the Module

This module mounts to the following cable bases:

• 1792D-CBFM for KwikLink™ flat media installation

• 1792D-CB12 for 12mm drop cable installation

• 1792D-CB18 for round media trunk connection

• or other optional cable base assembly.

IMPORTANT

To install the module:

IMPORTANT

1. Position the module over the mounted cable base. Align the

three captive screws in the module with the accepting
receptacles in the base.

2. Tighten the screws to secure the module to the base.

The cable base should already be installed. See
publication 1792D-IN009B-EN-P to install the cable
base.

Proper alignment of the screws is necessary to
complete the connections between the module
contacts and the cable contacts.

Connect the Input Cord Sets to the MaXum Module

This module uses 5 pin micro (12mm) style PCB mounted connectors.
Eight micro caps cover the connectors on your module. Remove the

caps and connect your cord sets to the appropriate ports. This
product has two inputs per connector.

Use the micro caps to cover and seal unused ports. A pinout diagram
for the connectors is shown next.

Please refer to publication 889-CP001A-EN-P and 889-TD001A-EN-P
for Rockwell Automation cables and cord sets offerings.

IMPORTANT

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.

ATTENTION

• Make sure all connectors and caps are

securely tightened to properly seal the
connections against leaks and maintain IP67
requirements.

ÿ

• For maximum noise immunity, input cable

return wires must be properly terminated.
When inputs are connected in loopback,
return wires should be connected together.

• I/O cable length should be less than 30

meters.

DeviceNet Cables

DeviceNet cables are described in the installation publications for the
cable base assembly of your choice. Refer to the following
publications:

Installation Guide

• DN-6.7.2 DeviceNet Cable Planning and Installation Manual

Communicate With Your ArmorBlock MaXum I/O Module

This ArmorBlock module’s I/O is exchanged with the master through
a poll, change-of-state, or cyclic connection.

The module consumes and produces I/O data as follows:

Type of I/O Connections Consumes Produces

Cyclic 0 Byte 3 Bytes
Polled 0 Byte 3 Bytes
Change-of-State 0 Byte 3 Bytes

Cyclic - allows configuration of the block as an I/O client. The block
will produce its I/O cyclically at the rate configured.

Polled - a master initiates communication by sending its polled I/O
message to the module. The 8 input m odule cans the inputs and faul t
bits producing a response that reflects their status.

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 m odule is alive
and ready to communicate.

Refer to the table below for the word/bit definitions.
