Install Your ArmorBlock LP2 I/O Module
To install the module you must:
• Set the node address and baud rate.
• Mount the module.
• Connect the input/output cord sets to the LP2 module.
• Communicate with your ArmorBlock LP2 I/O module.
Each of these steps is discussed in detail in the following procedures.
Set the Node Address and Baud Rate
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.

Connect the Input/Output Cord Sets to the LP2 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 cord sets to the appropriate ports. This product has two
input or outputs per I/O connector. Use a “Y” splitter cable for access to all
I/O 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 connectors is shown below.

• Make sure to connect the proper color coded cables
together. DeviceNet cables should connect with
DeviceNet cables and auxiliary outputs should match
auxiliary outputs.
• 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.

Output Power and DeviceNet Cable
Refer to the DeviceNet Cable System Planning and Installation Manual,
publication DN-6.7.2, for more information on output power and
DeviceNet cables for your application.
Communicate with Your ArmorBlock LP2 I/O 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 follows:
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 module. The 8 input/8 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 that the I/O module is
alive and ready to communicate. Consumption occurs when data changes
and the master produces new output data to the I/O module.
