(Catalog Number 1792-IB8XOB8PLP)
This 1792 ArmorBlockI/O block module (Cat. No.
1792-IB8XOB8PLP)
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.

Set the Node Address
Each ArmorBlock-LP comes with its internal program set for node
address 63 and a communication rate of 125K bps. 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
Set up a system (as shown below) to communicate with your
ArmorBlock module to set the node address and communication rate to
meet your system requirements.

Seven micro caps are included with your module. Use these caps to
cover and seal unused ports. Pinout diagrams for the connectors are
shown below.
!ATTENTION: Make sure all connectors are securely
tightened to properly seal the connections against leaks and
maintain IP67 requirements.

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:

ArmorBlock-LP 8 Input/8 Output Module 7
Publication 1792-5.8 – December 1997
Type of I/O Connections Consumes Produces
Polled 1 Bytes 2 Bytes
Bit Strobe 0 Bytes 2 Bytes
Change of State 0 Bytes 2 Bytes
Polled device – a master initiates communication by sending its polled
I/O message to the ArmorBlock module. The 8 input/8 output module
consumes the message, updates outputs, and produces a response that
reflects the status of 1) its inputs, and 2) any input or output faults.
Change of state device – productions occur when an input or fault
condition changes. 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 8 input/8
output module consumes the message, and produces a response that
reflects the status of inputs and outputs.
Refer to the table below for the word/bit definitions.

Word Bit Description
Produces 00–07 Input Status bits – when the bit is set (1), the input is on. Bit 00
corresponds to input 1A, bit 01 corresponds to input 3A, bit 02 to
input 5A, bit 03 input 7A. Bit 04 corresponds to input 1B, bit 05 to
input 3B, bit 06 to input 5B, and bit 07 to input 7B.
Produces 00–05 Reserved

06 OF = output fault status bit – indicates presence of field power
(default). Can also indicate no load or overload condition when
diagnostics are enabled. Refer to publication 1792-2.1, ArmorBlock
and AmorBlock-LP Product Data.
07 IS = Sensor source voltage fault bit – this bit is set (1) when the
sensor source voltage is faulted.
Consumes 00–07 Output bits – when the bit is set (1), the output is on. Bit 00
corresponds to output 2A, bit 01 corresponds to output 4A, bit 02 to
output 6A, bit 03 output 8A. Bit 04 corresponds to output 2B, bit 05
to output 4B, bit 06 to output 6B, and bit 07 to output 8B.

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.
