Cat. No. 1792-IB16LP
This 1792 ArmorBlockI/O block module (Cat. No. 1792-IB16LP)
contains I/O circuits, a built-in power supply, and a built-in DeviceNet
I/O adapter. Because of its sealed housing, this 1792 I/O block requires
no enclosure. It is compatible with PLC or SLC programmable
controllers using DeviceNet scanners. The I/O values are accessible
from the PLC or SLC programmable controller data table.
This ArmorBlock-LP module has no switches to set. You set module
parameters using the DeviceNet Manager Software (cat. no. 1787-MGR)
or similar configuration tool.

Installation Instructions

ArmorBlock-LP 16 Input Module2
Publication 1792-5.6 – September 1997
Low Voltage Directive
This apparatus is also designed 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 that the above norm requires, see the
appropriate sections in this manual, 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 Y our ArmorBlock Module
Installation of the ArmorBlock module consists of:
•setting the node address and communication rate in the ArmorBlock
module
•mounting the ArmorBlock module
•connecting the wiring
•communicating with your module
Set the Node Address
Each ArmorBlock comes with its internal program set for node address
63 and a communication rate of 125Kbps. To set the node address and
communication rate, you need the following:
•host computer with DeviceNet Manager Software (or similar
configuration software tool)
•1770-KFD RS-232 module (or similar interface)
•suitable cables to connect the 1770-KFD to your module and to
connect the 1770-KFD to your host computer

Seven micro plugs are included with your module. Use these plugs to
cover and seal unused ports. Pinout diagrams for these connectors are
shown below.
!ATTENTION: Make sure all connectors are securely
tightened to properly seal the connections against leaks and
maintain IP67 requirements.
Connecting the Input Wiring
Connect input wiring to the micro-connectors which screw into mating
connectors on the front of the block.
Make connections as shown below.

Communicate with Your ArmorBlock Module
This ArmorBlock module’s I/O is exchanged with the master through a
poll, bit strobe or change of state connection.
When set for Polled, Bit Strobe, or change of state, the module consumes
and produces as follows:
Type of I/O
Connection Consumes Produces
Polled 0 Bytes 3 Bytes
Bit Strobe 0 Bytes 3 Bytes
Change of State 0 Bytes 3 Bytes
Polled device – a master initiates communication by sending its polled
I/O message to the ArmorBlock module. The 16 input module scans the
inputs and fault bit producing a response that reflects their status.
Change of state – productions occur when an input changes or an input
source voltage fault occurs. If neither has occurred within the “expected
packet rate,” a heartbeat production occurs. This heartbeat production
tells the scanner module that the ArmorBlock module is alive and ready
to communicate.
Bit Strobe device – a master initiates communication by sending its bit
strobe I/O message. All bit strobed devices then respond. The 16 input
module scans the inputs and fault bits, producing a response that reflects
their status.

Note: This module contains a circuit to protect the DeviceNet power supply from short circuits in
an attached sensor or sensor cable. If you connect a sensor while the module is powered,
the surge current produced by the sensor can cause the module to fault. This operation is
normal.
