ArmorBlock LP2 8 Sinking Input Module 3
Install Your ArmorBlock LP2 I/O Module
To install the module:
• Set the node address and baud rate.
• Mount the module.
• Connect the input cord sets to the LP2 module
• Communicate with your ArmorBlock LP2 module.
More detailed information about each of these steps is in the following
procedures.
Set the Node Address
Set the node address using RSNetWorx for DeviceNet™ software,
DeviceNetManager™ software, or another software 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.

2. 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 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 cables to the appropriate ports. This product has two
inputs per connector. Use a “Y” splitter cable for access to all input
connections. For more information on these cables, see the Product Data
guide, publication 1792-2.1.
Use the micro caps to cover and seal unused ports. A Pinout diagram for
the connector is shown below.

ATTENTION:
!
• Make sure to connect the proper color coded cables
together. DeviceNet cables should connect with
DeviceNet cables.
• 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 cable return wires
must be properly terminated. When inputs 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 Module
This ArmorBlock module’s I/O is exchanged with the master through a
poll, change of state, or cyclic connection.
The module produces input data as follows:
Type of I/O Connections Consumes Produces
Cyclic 0 Bytes 2 Bytes
Polled 0 Bytes 2 Bytes
Change of State 0 Bytes 2 Bytes
Cyclic - allows configuration of the block as an I/O client. The block will
produce 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 module consumes the message,
updates inputs, and producing a response. The response has input data and
input faults.
Publication 1792D-5.47 - August 1999
6 ArmorBlock LP2 8 Sinking Input Module
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 input data to the I/O block.
