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.

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.
