1.0Introduction
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

Introduction1
2.0Installation
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.
2.1Installing the DeviceNet Interface
Use the following procedure to install the DeviceNet
Interface into 520, 820i, and 920i indicators.

Figure 2-1. Option Installed on 820i CPU Board
2.1.1Installing 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.

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

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.

2.1.2Installing 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.
