1.0 Introduction
The DeviceNet Interface returns weight and status information from a 520, 720i, 820i, or 920i indicator to a master
controller and provides limited control of indicator functions to the programmer. Indicator configuration and
calibration cannot be performed through the DeviceNet Interface.
The DeviceNet Interface functions as a
network. It acts as a group-two-only server on the network. At this time only one polled I/O connection is
supported, though DeviceNet also supports explicit, bit-strobed, and change-of-state/cyclic connections. These
connections may be included at a later date.
The master controller sends commands to the indicator
in the output command format. The DeviceNet Interface returns the weight and status data in the input command
format. These actions are referred to as polled I/O. See Section 3.0 for descriptions of the polled I/O comma

2.0 Installation
CAUTION
WARNING
The DeviceNet Interface hardware consists of a
dual-board option card. DeviceNet-specific functions
are provided by a DeviceNet module, which is
factory-installed onto a bus adapter card. The bus
adapter card plugs into an open option card slot on the
520, 820i, or 920i CPU board (or expansion board) and
provides power and access from the indicator bus to the
DeviceNet module.
This section describes the procedures used to install the
DeviceNet Interface
indicators, connect communications cables, and set the
baud rate and node address DIP switch on the
DeviceNet module.
2.1 Installing the DeviceNet Interface
Use the following procedure to install the DeviceNet
Interface into 520, 820i, and 920i indicators.
into the 520, 820i, and 920i
Figure 2-1. Option Installed on 820i CPU Board
2.1.1 Installing DeviceNet Option in the 720i, 820i or 920i
Use the following procedure to install the DeviceNet
Interface in the 720i, 820i or 920i indicator:
1. Disconnect indicator from power source.
Disconnect power before removing
indicator backplate.
The
820i and 920i have no on/off switch.
Before opening the unit, ensure the power
cord is disconnected from the power
outlet.
2. Open indicator enclosure. For indicator models
with backplates, place indicator face-down on
an antistatic work mat. Remove screws that hold
the backplate to the enclosure body.
Use a wrist strap to ground yourself and
protect components from electrostatic
disc
harge (ESD) when working inside the
indicator enclosure.
3. Carefully align the large connector (J1) on the
bus adapter card with connector J6 on the 820i,
J12 on the 720i, or J5 or J6 on the 920i CPU
board. Press
down to seat the bus adapter card in
the CPU board connector.
4. Use the screws and lockwashers provided in
the
option kit to secure the other end of the
option card to the threaded standoffs on the
CPU board (see Figures 2-1 and 2-2).
5. Wire the card to the network as described in
Section 2.2 on page 4.
6. Set DIP switch as described in Section 2.3 on
page 4.
7. Use cable ties to secure loose
cables inside the
enclosure.
Figure 2-2. Option Installed on 920i CPU Board
8. For indicator models that include a backplate,
position the backplate over the enclosure and
reinstall the backplate screws. For the 820i or
920i desktop and universal models, use the
torque pattern shown in Figure 2-3 to prevent
distorting the backplate gasket. Torque screws

3. Carefully align the large option card connector
with connector J2 on the CPU board (see
Figure 2-5). Press
down to seat the option card
in the CPU board connector.

4. Use screws provided in the option kit to secure
the other end of the option card to the threaded
standoffs on the CPU board.
5. Install terminal block end of cable assembly to
DeviceNet o
ption card.
6. Remove existing cover plate.
7. Re-use kep nuts to secure DeviceNet cover
plate
to standoffs located on inside of
enclosure backplate (see Figure 2-6).
8. Once cabling is complete, position the cover
over the enclos
ure and reinstall the screws.
9. Reconnect power to the indicator.

2.1.2 Installing DeviceNet Option in the 520
Use the following procedure to install the DeviceNet
Interface in the 520 indicator:
1. Disconnect indicator from power source.
Disconnect power before removing
indicator enclosure cover.
The
520 has no on/off switch. Before
opening the unit, ensure the power cord is
disconnected from the power outlet.
2. Place indicator on an antistatic work mat.
Remove screws that hold the enclosure cover
to the enclosure body.
Use a wrist strap to ground yourself and
protect components from electrostatic
disc
harge (ESD) when working inside the
indicator enclosure.

10. The indicator automatically recognizes all
installed option cards when the unit is powered
on. No hardware-specific configuration is
required to identify the newly-installed
DeviceNet interface to the system.

2.2 DeviceNet Network Connections
Note
Note
Feed DeviceNet network cable through cord grip.
Allow enough cable for routing along inside of
enclosure to connector on the DeviceNet module.
Connect network cables to connector on the DeviceNet
module (see Figure 2-4), then use cable ties to secure
network cables to the cable tie mounts.
Table 2-1shows the wiring color codes used for
DeviceNet connections.
Verify the color-coding or wiring scheme for
your network equipment before wiring to the
eNet Interface.

3.0 Commands
Note
Commands are used by the DeviceNet master device to
send and receive data from the DeviceNet Interface as
integer or floating-point data. The master sends eight
bytes in the output format (used to write commands to
the indicator) and reads eight bytes in the input format
(used to read data from the indicator).
Decimal Point Handling
Integer commands return no decimal point information
to the master. For example, a value of 750.1 displayed
on the indicator is returned to the master as 7501.
Floating point commands support decimal point
information with no special handling.
3.1 Output Command Format
To perform a command, the master uses the output
command format to send four 16-bit words to the
DeviceNet Interface. These four words contain the
command and any parameters necessary to execute it.
The output command format is shown in Table 3-1.
Word Description
Word 1 Command number
Word 2 Parameter

The contents of each output command format word are
described below:
Command number
The number representing the indicator command is
sent in the first word. Table 3-2 lists the commands that
can be specified for 52
indicators.
A lockout feature that looks for any change in
the output format data is incorporated into the
indi
inundation by the same command. Repeated commands
must be separated by any other valid
command/parameter/value combination.

Table 3-2. 520/720i/820i/920i Remote Commands
Parameter value
To allow communication with a multi-scale indicator,
the scale number is sent in the second word of the
output command format. Zero (0) represents the
current scale. Certain commands require a parameter
other than a scale number, such as a slot number,
setpoint number, or other selection parameter. See the
command descriptions in Section 3.3 for specific
command requirements.
Value
The third and fourth words of the output format are
used to pass value data on certain commands. Values
entered in these words are treated as unsigned long
integers or floating-point values, depending on the
command.
3.2 Input Command Format
In response to a command, the DeviceNet Interface
returns data and status information to the master as four
16-bit words. This information is returned in the input
command format shown in Table 3-3.
The value type can be set for those commands that do
not specify in
command 0x000 to specify integer data or command
0x100 for floating-point data. The value type is
returned in the status word (bit 14) of the input format.

The first word echoes the command number. If the
command fails or is not recognized, the negative of the
command number is returned to signal the error.
