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.

3.0 Commands
Commands are used by the primary device to send and receive data from the interface as
integer or floating-point data. The primary sends eight bytes in the output format to write
commands to the indicator and reads eight bytes in the input format to read data from the
indicator.
Decimal Point Handling
Integer commands return no decimal point information to the primary.
For example, a value of 750.1 displayed on the indicator is returned to the primary as 7501.
Floating point commands support decimal point information with no special handling.
3.1 Output Data Format
To perform a command, the primary uses the output command format to send four
16-bit words to the interface. These four words contain the command and any parameters
necessary to execute it. The output command format is shown in Table 3-1.
See Section 3.1.1 on page 11 for BYTE swapping parameters.
A lockout feature, incorporated into the indicator receive mechanism, looks for
change in the output format data to prevent inundation by the same command.
See affected commands noted in Table 3-3 on page 9 with an (*).
Repeated commands must be separated by any other valid command/parameter/
value combination.

Parameter Value
In 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 on page 15 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.
Command Number
The number representing the indicator command is sent in the first word.
Table 3-3 lists the commands that can be specified for indicators.
Some commands may not be available on all indicators.

3.1.1 BYTE Swapping
See the Ports Menu in the indicator manual.
The indicator sends and receives data in integer format.
The standard format is as follows for all input and output values:
High BYTE – Low BYTE
If the indicator FLDBUS/SWAP parameter is set to YES, then the BYTE order changes to:
Low BYTE – High BYTE
Example: If the weight on the scale reads 10 lbs and a value of 2560 is
displayed in the PLC, either swap the BYTES in the PLC or change the SWAP
parameter to YES
3.2 Input Data Format
The interface returns data and status information to the primary as four 16-bit words in
response to a command. The input command format is shown in Table 3-4.
The value type can be set for commands not specifying integer or floating point data by
sending the command 0x000 to specify integer data, or sending command 0x100 to specify
floating-point data. The value type is returned in the status word (bit 14) of the input format.
See Section 3.1.1 for BYTE swapping parameters.

3.2.3 Value
Weight data is returned to the primary in the third and fourth words of the input command
format, depending on the command and the value type. The weight data returned is the
displayed weight after the command is executed, unless the command specifies otherwise.
A negative value is returned in the two’s compliment format.
3.2.4 Setting a Float Value
Setting a float value in a setpoint requires the value to be sent in two separate integer values.
Most PLCs have a mechanism to take a float value and separate it into to integer values.
Example: The following must be sent in the output words to set the value of
Setpoint #1 to 10000.
Command word = 304
Parameter word = 1
MSW = 17948
LSW = 16384
3.2.5 Reading a Float Value
When a float value is read it will be returned in two integers representing the float value.
The PLC must combine MSW and LSW integer values back into a float value.
Example: The following is returned in the input words if the weight on the scale
is 800.5.
Command Word = 288
Status word = Scale status
MSW= 17480
LSW = 8192
