This ArmorBlock MaXum™ I/O module (Cat. No. 1792D-2BVA2D) 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 2 inputs with alarm and 2 outputs. Inputs are 24V dc
automatically configured for PNP (sourcing) or NPN (sinking)
devices. Outputs are also configured for sourcing. Two self-protected
24V dc outputs can provide up to 1.0 amp each. Diagnostic features
included 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.

ArmorBlock MaXum 2 Input with Alarm/ 2 Output Module Series B 3
Install Your ArmorBlock MaXum I/O Module
To install the module:
• Set the node address
• Mount the module to the cable base
• Connect the cord sets
• Communicate with the module
Each of these steps is explained in more detail in the following
procedures.
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.
Publication 1792D-IN015B-EN-P - September 2000
4 ArmorBlock MaXum 2 Input with Alarm/ 2 Output Module Series B
Refer to the illustration of the node address below.
Example: Node address is set at 62, see small black dots.
30703-M
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
• 1792D-CB18PT for 4 connector blocks needing round media
DeviceNet and output power
• or other optional cable base assembly
IMPORTANT
The cable base should already be installed. See
publication 1792D-IN009B-EN-P for more
information on installing the cable base.
Publication 1792D-IN015B-EN-P - September 2000
ArmorBlock MaXum 2 Input with Alarm/ 2 Output Module Series B 5
To install the module:.
IMPORTANT
Proper alignment of the screws is necessary to
complete the connections between the module
contacts and the cable contacts.
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.
Note: Dimensions change according to the cable base and module
combination used.

Connect the Cord Sets to the MaXum Module
This module uses 5 pin micro (12mm) style PCB mounted connectors.
Four micro caps cover the connectors on your module. Remove the
caps and connect your cord sets to the appropriate ports.
Use the micro caps to cover and seal unused ports. A pinout diagram
for the connectors is shown next.

ATTENTION
• 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.

8 ArmorBlock MaXum 2 Input with Alarm/ 2 Output Module Series B
Communicate With Your ArmorBlock MaXum Module
This ArmorBlock module’s I/O is exchanged with the master through
a polled, change-of-state, or cyclic connection.
The module consumes and produces I/O data as shown:
Type of I/O Connections Consumes Produces
Cyclic 1 Byte 2 Bytes
Polled 1 Byte 2 Bytes
Change-of-State 1 Byte 2 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 ArmorBlock module. This 2 input / 2 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 ArmorBlock
MaXum module is alive and ready to communicate. Consumption
occurs when data changes and the master produces new output data
to the I/O block.
