European Union Directive Compliance
If this product has the CE mark it is approved for installation within the
European Union and EEA regions. It has been designed and tested to meet
the following directives.
EMC Directive
This product is tested to meet Council Directive 89/336/EEC
Electromagnetic Compatibility (EMC) and the following standards, in
whole or in part, documented in a technical construction file:
• EN 50081-2 EMC - Generic Emission Standard, Part 2 - Industrial
Environment
• EN 50082-2 EMC - Generic Immunity Standard, Part 2 - Industrial
Environment
This product is intended for use in an industrial environment.
Low Voltage Directive
This product is tested to meet Council Directive 73/23/EEC Low Voltage,
by applying the safety requirements of EN 61131-2 Programmable
Controllers, Part 2 - Equipment Requirements and Tests.
For specific information required by EN 61131-2, see the appropriate
sections in this publication, as well as the following Allen-Bradley
publications:
• Industrial Automation Wiring and Grounding Guidelines For Noise
Immunity, publication 1770-4.1
• Automation Systems Catalog, publication B111
Install Your ArmorBlock LP2 I/O Module
To install the module:
• Set the node address and baud rate.
• Mount the module.
• Connect the unit to the DeviceNet trunk and the auxilary power source.
• Connect the cord sets.
Set the Node Address and Baud Rate
Set the node address using RSNetworx for DeviceNet software,
DeviceNetManager software, or another configuration tool. 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.

Connect the grey DeviceNet cable to the DeviceNet trunk. Use the
1485P-P1R5-MN5R1 T-Part tap to make the connection to round
media. Use the 1485P-P1E4-R5 to connect to the Kwik Link flat media
system.
Connect the Input / Output Cord Sets to the LP2 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. Pinout diagrams for the
connectors are shown next.

ATTENTION:
• Make sure to connect the proper color coded cables
together. DeviceNet cable should connect with DeviceNet
cables and auxillary ouput should match auxillary output.
• 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.

Communicate With Your ArmorBlock LP2 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:

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 and the status of the Auxiliary power.
Change of state - productions occur when an input changes. If no input
change occurs within the expected packet rate, a heartbeat production
occurs. This heartbeat production tells the scanner module that the
ArmorBlock LP2 module is alive and ready to communicate. Consumption
occurs when data changes and the master produces new output data to the I/
O block.
