ArmorBlock MaXum 8 Input / 8 Output
Module Series B

(Cat. No. 1792D-8BVT8D)

This ArmorBlock MaXum™ I/O module (Cat. No. 1792D-8BVT8D) 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 and 8 outputs accessed through Y splitter cables.
Inputs are 24V dc automatically configured for PNP (sourcing) or NPN
(sinking) devices. Eight self-protected 24V dc outputs can provide up to 0.5
amp each. Diagnostic features are short circuit, open wire, and no load
detection reported to the point level. Local logic control has been added to
the Series B version of this product.

Example: Node Address is set at 62, see small black dots.

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
Example: The last setting was 40. If a change is made to 68, and then you
power up, the address will default to 40.

IMPORTANT

IMPORTANT

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-CB18P for round media DeviceNet and output power

• or other optional cable base assembly.

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

To install the module:

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

Publication 1792D-IN020B-EN-P - September 2000

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 with a torque of 8 inch-pounds to secure the
module to the base.

Connect the Input / Output 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
or outputs per I/O connector. Use a “Y” splitter cable for access to all I/O
connections.

• 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.

• I/O cable length should be less than 30 meters.

I/O connectors for this module are shown below.

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

8 ArmorBlock MaXum 8 Input / 8 Output Module Series B

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 1 Byte 4 Bytes
Polled 1 Byte 4 Bytes
Change-of-State 1 Byte 4 Bytes

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 8 input / 8 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.
