ArmorBlock MaXum 8 Output Module Series B 3

Install Your ArmorBlock MaXum I/O Module

To install the module you must:

• Set the node address

• Mount the module to the cable base

• Connect the output cord sets to the MaXum module

• Communicate with your ArmorBlock MaXum I/O module

More detailed information about each of these steps is 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™ software, or another software configuration tool. Setting
the switches between 64 to 99 lets the software have address control.

Each module is shipped with the node address set to 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.

Refer to the illustration of the node address below.

41462

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 Base

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 connection

• or other optional cable base assembly

IMPORTANT

Publication 1792D-IN003B-EN-P - September 2000

The cable base should already be mounted. See
publications 1792D-IN009B-EN-P (CBFM & CB12)
or 1792D-IN036B-EN-P (CB18, CB18P) for more
information on installing the cable base.

To install the module:

ArmorBlock MaXum 8 Output Module Series B 5

IMPORTANT

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

Connect the 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 cables to the appropriate ports.

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

ATTENTION

!

Publication 1792D-IN003B-EN-P - September 2000

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 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 output data as follows:

Type of I/O Connections Consumes Produces

Cyclic 1 Bytes 2 Bytes

Polled 1 Bytes 2 Bytes

Change-of-State 1 Bytes 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 module. This 8 output module consumes the
message, updates outputs and produces a response. The response
has 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.

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