1.0 Introduction
The DeviceNet interface can be used to read and write data to the indicator using a PLC or
another primary controller. This manual provides information for installation and use of this
product.
The DeviceNet interface is installed inside the indicator enclosure and installation in NEMA
Type 4X stainless steel enclosures permits use in washdown environments.
See the indicator installation manual for additional installation information and detailed
descriptions of indicator functions.
Some procedures described in this manual require work inside the indicator
enclosure. These procedures are to be performed by qualified service
personnel only.
Manuals and additional resources are available on the Rice Lake Weighing Systems
website at www.ricelake.com
Warranty information can be found on the website at www.ricelake.com/warranties
1.1 Overview
The DeviceNet Interface returns weight and status information from an indicator to a primary
controller and provides limited control of indicator functions to the programmer. Indicator
configuration and calibration cannot be performed through the DeviceNet Interface.
The Installation functions as a Communications Adapter Device (ODVA profile 12) on a
DeviceNet 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 primary controller sends commands to the indicator through the DeviceNet Interface by
writing the commands in the output command format. The Installation returns the weight and
status data in the input command format. These actions are referred to as polled I/O.
See Section 3.0 on page 8 for descriptions of the polled I/O commands.

2.0 Installation
DeviceNet Interface specific functions are provided by a DeviceNet module.
The module plugs into an open option card slot on the CPU board and provides power and
access from the indicator bus to the DeviceNet module.
See the indicator Technical Manual for installation instructions.
The interface option cards of the 1280 Enterprise Series and 880 universal and panel mount
indicators share the same carrier board (PN 164756). The carrier board plugs into an open slot
on the CPU board and provides power and access from the indicator bus to the module.
The assembly steps of the carrier board and modules vary between the 1280, 880 universal
mount, and 880 panel mount.
• 1280 interface option card kits are shipped with the module and the carrier board already
assembled
• 880 interface option card kits are shipped with the module and carrier board separated
― 880 universal mount module can be assembled to the carrier board before
installing
― 880 panel mount carrier board must be installed before assembling the module to
the carrier board
Figure 2-1. Interface Option Card Kit
The indicator automatically recognizes all installed option cards when the unit is powered on.
No hardware-specific configuration is required to identify an installed card to the system.
Always disconnect the power before opening an enclosure.
Interface option cards are not hot swappable.
A grounding wrist strap must be worn to protect components from
electrostatic discharge (ESD) when working inside an enclosure or controller
assembly.

1280 Installation Instructions
1. Disconnect power to the indicator.
2. See the 1280 technical manual (PN 167659) to gain access to the Controller Assembly
box for the specific model.
3. Remove the screw securing the intended slot cover plate of the Controller Assembly box,
set the slot cover plate aside and save the screw.
4. Mount the faceplate on module and slide module board assembly into place within the
slot.
5. Secure the faceplate and module board assembly into place with the previously removed
screw.
Interface cable is routed through a cord grip in Universal and Wall mount
enclosures.
Alternately, a chassis mounted connect can be installed in the enclosure.
6. See 1280 technical manual to reinstall the Controller Assembly box.

880 Universal Installation Instructions
1. Disconnect power to the indicator.
2. Remove the backplate of the universal enclosure to access the CPU board.
3. Carefully slide the module into the J1 connector on the carrier board, ensuring that the
pins of J1 are not bent.
4. Ensure that the module is fully seated in the carrier board with the board hooks on the
bottom of the module aligned with the carrier board.
5. Tighten module screws on the front of the module to lock the board clamps of the module
to the carrier board.
Figure 2-4. Bottom of Carrier Card with Module Installed
Screws are tightened with a T9 Torx bit.
If the module is not fully seated on the carrier board, the clamps will push the
module away from the board rather than securing the board to the module.
This can potentially cause damage to the connector.
6. Carefully align the J5 connector on the bottom of the carrier board with the J8 option card
slot on the CPU board.
7. Press down on the carrier board with module until it is seated on the CPU board
connector.
8. Use the screws provided in the option kit to secure the carrier board to the threaded
standoffs on the CPU board (faceplate not needed).
9. Connect and properly run necessary cable.
10. Reinstall the enclosure backplate.

880 Panel Mount Installation Instructions
1. Disconnect power to the indicator and then disconnect the display cable.
2. Remove the backplate of the panel mount enclosure to access the CPU board.
3. Carefully align the J5 connector on the bottom of the carrier board (module currently not
attached) with J8 option card slot on the CPU board.
4. Press down on the carrier board until it is seated on the CPU board connector.
5. Use the screws provided in the option kit to secure the carrier board and faceplate to the
threaded standoffs on the CPU board.
6. Carefully slide the module through the faceplate to the J1 connector on the carrier board,
ensuring that the pins of J1 are not bent.
7. Ensure that the module is fully seated in the carrier board with the board hooks on the
bottom of the module aligned with the carrier board.
8. Tighten T9 Torx screws on the front of the module to lock the board clamps of the module
to the carrier board.
Screws are tightened with a T9 Torx bit.
If the module is not fully seated on the carrier board, the clamps will push the
module away from the board rather than securing the board to the module.
