1791D CompactBlock™ I/O modules are stand-alone 24V dc Block
I/O products that communicate via a DeviceNet™ link. Each
DeviceNet node consists of either one base module or one base
module coupled with one expansion module.

NOTE: The 1791D-4B0 module cannot be expanded.

CompactBlock I/O modules must be installed in a secondary
enclosure. Base modules are equipped with 4 to 16 points and
expansion modules are equipped with 16 I/O points.

Sinking or sourcing inputs are 24V dc IEC Type 3 compatible. Sinking
or sourcing self-protected 24V dc outputs can provide up to 0.5 amp
each.

Environment and Enclosure

This equipment is intended for use in a Pollution
Degree 2 industrial environment, in overvoltage
Category II applications (as defined in IEC
publication 60664-1), at altitudes up to 2000 meters
without derating.

This equipment is considered Group 1, Class A
industrial equipment according to IEC/CISPR
Publication 11. Without appropriate precautions,
there may be potential difficulties ensuring
electromagnetic compatibility in other
environments due to conducted as well as radiated
disturbance.

This equipment is supplied as "enclosed"
equipment. It should not require additional system
enclosure when used in locations consistent with
the enclosure type ratings stated in the
Specifications section of this publication.
Subsequent sections of this publication may
contain additional information regarding specific
enclosure type ratings, beyond what this product
provides, that are required to comply with certain
product safety certifications.

See NEMA Standards publication 250 and IEC
publication 60529, as applicable, for explanations
of the degrees of protection provided by different
types of enclosure. Also, see the appropriate
sections in this publication, as well as the
Allen-Bradley publication 1770-4.1 ("Industrial
Automation Wiring and Grounding Guidelines"),
for additional installation requirements pertaining
to this equipment.

Installing CompactBlock I/O

Follow these steps, to install the 1791D I/O module:

1. Set the Node Address on the Base Module.

2. Mount the Block(s).

3. Connect the Input/Output Wires to the Block.

4. Connect the DeviceNet Cable.

5. Remove the terminal block.

6. Insert the terminal block.

7. Communicate with the 1791D Module.

These steps are explained in detail in the following
procedures.

Preventing Electrostatic Discharge

This equipment is sensitive to electrostatic
discharge, which can cause internal damage and
affect normal operation. Follow these guidelines
when you handle this equipment:

• Touch a grounded object to discharge potential static.

• Wear an approved grounding wriststrap.

• Do not touch connectors or pins on component boards.

• Do not touch circuit components inside the equipment.

• If available, use a static-safe workstation.

• When not in use, store the equipment in appropriate

static-safe packaging.

CompactBlock I/O for DeviceNet Modules Series D 5

Set the Node Address on the Base Module

Each 1791D base module comes with its internal program set for
node address 63. To reset the node address, adjust the switches
located behind the door on top of the module. The two switches are
most significant digit (MSD) and least significant digit (LSD).

The switches can be set between 00 and 63. Use the node adjusting
tool provided in the package, or a small bladed screwdriver to rotate
the switches.

The rotary switches are read at module power up only. Switch
settings between 64 and 99 cause the module to use the last valid
node address stored internally.

Connect the DeviceNet Cable

Refer to the following information when connecting the DeviceNet
wire to the 1791D block I/O.

If you connect or disconnect the
communications cable with power applied to
this module or any device on the network, an
electrical arc can occur. This could cause an
explosion in hazardous location installations.

Insert the Terminal Block

To insert the CompactBlock terminal block.

1. Insert the terminal block by aligning it and pushing it back

until it rests against the back of the module.

2. Tighten the screws on each side of the terminal block until the

terminal block is firmly in place.

Communicate With the 1791D Module

Determine the Baud Rate for Your DeviceNet Connection

All 1791D CompactBlock I/O for DeviceNet modules contain the
autobaud feature. Autobaud lets the modules automatically detect the
baud rate for the network upon connection to the live network.

The 1791D base modules’ I/O is exchanged with the master through
a polled, cyclic or change of state connection.

Polled - master initiates communication by sending its polled I/O
message to the 1791D module. The module consumes the message,
updates any outputs, and produces a response. If inputs are present,
the response contains the input data.

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.

Change of state - production occurs when an input changes. If no
input change occurs within the expected packet time, a heartbeat
production occurs. This heartbeat production tells the scanner
module that the 1791D 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 block.

Publication

1791D-IN003A-EN-P - June 2003

16 CompactBlock I/O for DeviceNet Modules Series D

The module produces 1 byte for every 8 inputs. Similarly, the module
consumes 1 byte for every 8 outputs. When an expansion module is
connected, an additional byte will be returned indicating the health of

the expansion module.

IMPORTANT

When installing an expansion module, refer to the
table below to see how many bytes are produced
and consumed by the modules.

Remember, though, when configuring your CompactBlock I/O
application, these values are entered as bytes received (R

transmitted (T

) by the scanner.

x

) and bytes

For example, a Base input module produces 2 bytes and consumes 0
bytes. In such a case, the scanner connected to the Base Input
module will receive (R
