Installation Instructions
Cat. No. 1792-OB8PLP
This 1792 ArmorBlock I/O block module (Cat. No. 1792-OB8PLP)
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.

Install Your ArmorBlock-LP Module
Installation of the ArmorBlock-LP 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-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.

ArmorBlock-LP 8 Output Module 7
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 Connections Consumes Produces
Polled 1 Bytes
Bit Strobe
Change of State
0 Bytes
0 Bytes
1 Byte
1 Byte
1 Byte
Polled device – a master initiates communication by sending its polled
I/O message to the ArmorBlock module. The 8 output module consumes
the message, updates outputs, and produces a response that reflects the
status of its output faults.
Change of state device – productions occur when a fault condition
changes. If no fault condition occurs 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 output
module consumes the message, and produces a response that reflects the
status of output faults.
