Environment and Enclosure
16 Input/16 Output Digital Embedded I/O Boards 3
ATTENTION
This equipment is intended for use in overvoltage Category II applications (as defined in
IEC publication 60664-1), at altitudes up to 2000 meters (6562 feet) 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 open-type equipment. It must be mounted within an
enclosure that is suitably designed for those specific environmental conditions that will be
present and appropriately designed to prevent personal injury resulting from accessibility
to live parts.The enclosure must have suitable flame-retardant properties to prevent or
minimize the spread of flame, complying with a flame spread rating of 5VA, V2, V1, V0 (or
equivalent) if non-metallic. The interior of the enclosure must be accessible only by the use
of a tool. Subsequent sections of this publication may contain additional information
regarding specific enclosure type ratings that are required to comply with certain product
safety certifications.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, for additional installation
requirements, Allen-Bradley publication 1770-4.1
• NEMA Standards publication 250 and IEC publication 60529, as applicable, for
explanations of the degrees of protection provided by different types of enclosure.
.
ATTENTION
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.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in use.

About the Board
The board is a 32-point I/O board that communicates via a DeviceNet network.
This board has 16 inputs and 16 outputs. Inputs are 24V dc sourcing or sinking.
Outputs are self-protected 24V dc sourcing (1799-D16U16B, 1799-D16U16BL) or
sinking (1799-D16U16V, 1799-D16U16VL).

Your package contains:

All mating connectors and mounting hardware must be ordered separately. This
table identifies the different connector and hardware options.

• mount the board (brackets, mounting plate, plastic cover).
• connect the board (DeviceNet network, I/O).
• communicate with your board.
• configure the parameters.
More detailed information about each of these steps is in the following procedures.
Set the Node Address
Valid node addresses are 00...63.
Set the node address by using the rotary switches or a DeviceNet configuration tool
such as RSNetWorx for DeviceNet software. Setting the switches between 64 and 99
allows the software to have address control.
Each board is shipped with the node address set to 63 in the board’s memory. The
rotary switches are set for position 99 at shipment. The switches are located near
the center of the board. The two switches are:
• MSD (most significant digit).
• LSD (least significant digit).
To reset the node address, use a screwdriver to rotate the switches. Line up the
small arrow on the switch with the number setting you wish to use.
The rotary switches are read only when you apply power to the board. Settings
between 64 and 99 cause the board to use the last valid node address stored in the
board’s memory.
Publication 1799-IN004F-EN-P - September 2008
6 16 Input/16 Output Digital Embedded I/O Boards
For example, the last setting in memory is 40. If a change is made to 68, and then
you apply power to the board, the address will default to 40.

The LSD (S2)
and MSD (S1)

The board is equipped with AutoBaud detect. AutoBaud allows the board to detect
the communication rate on your DeviceNet network and automatically adjusts to
that rate.
The board is shipped with AutoBaud enabled.

Mount the Board and Optional Cover
You can mount the board to a DIN rail by using DIN-rail brackets (catalog number
1799-BRKD) or to a mounting plate (catalog number 1799-MP32). For clear plastic
covers (catalog number 1799-COV32), reference the following instructions.
1. Place the four stand-offs onto the mounting screws and tighten.
2. Align the holes on the cover with the stand-offs.
3. Place the screws through the cover into the stand-offs and tighten.

Turn off the system power before conducting maintenance or inspection on an open board,
or in an area where an open board is installed.
If powering down the system is not feasible, ensure that any open boards are covered
during maintenance or inspection to prevent any direct exposure of a directed light source
to open boards.

Connect the Field Output Device to the I/O Connector (P1)
The 1799-D16U16B and 1799-D16U16BL boards have outputs that supply current to
your field output device (sourcing outputs).
The outputs on these boards are isolated in two groups of eight, with each group
requiring 24V dc power and 24V dc ground. Outputs 0...7 are powered from +24V
GRP 0 and return power via GRP 0 Return. Outputs 8...15 are powered from +24V
GRP 1 and return power via GRP 1 Return.
Use these wiring diagrams to connect both groups of outputs on these boards.

Connect the Field Input Device to the I/O Connector (P1)
The inputs on these boards are isolated in two groups of eight, with each group
providing a separate common signal. Inputs 0 to 7 share the Common In GRP 0
signal. Inputs 8 to 15 share the Common In GRP 1 signal.
The 1799-D16U16B, 1799-D16U16BL, 1799-D16U16V, and 1799-D16U16VL boards
have universal inputs that allow operation with either sourcing or sinking input
devices. The universal feature lets you configure the inputs as either sinking or
sourcing. Use these wiring diagrams to connect each group of inputs on the boards.
IMPORTANT
All field input devices in each group of eight must be of the same type, either sinking or
sourcing. The board will not operate if the types are mixed.

Communicate With Your Board
This board exchanges I/O with the master on the DeviceNet network through a
cyclic, polled, or change-of-state connection.
The 1799-D16U16B and 1799-D16U16BL boards consume and produce I/O data as
follows.
Cyclic — the board produces and consumes its I/O cyclically at the rate configured
by the master on the DeviceNet network.
Polled — the master initiates communication by sending its polled I/O message to
the board. The board consumes the message, updates any outputs, and produces a
response containing the input data.
Change-of-state — a production occurs when an input changes. A heartbeat
production occurs if no input condition change occurs within the expected packet
rate. This heartbeat production tells the master that the board is ready to
communicate. Consumption occurs when data changes and the master produces
new output data to the board.

1799-D16U16BL boards.

The 1799 I/O boards have eight parameters that are configurable through a
DeviceNet configuration tool such as RSNetWorx for DeviceNet software. The
DeviceNet configuration tools require an electronic data sheet (EDS) for the 1799
