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.

• WARNING: 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

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 12 for descriptions of the polled I/O commands.

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.
• 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.

Byte 1
Byte 2| Parameter
Byte 3
Byte 4| Value (MSW)
Byte 5
Byte 6| Value (LSW)
Byte 7

Table 3-1. 1280 Output Data Format
NOTE: See Section 3.1.1 on page 15 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 3-2 on page 13 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 19 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 3-2 lists the commands that can be specified for indicators. Some commands may not be available on all indicators.

BYTE Swapping
NOTE: 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

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 3-3.
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.

Byte 1
Byte 2| Status
Byte 3
Byte 4| Value (MSW)
Byte 5
Byte 6| Value (LSW)
Byte 7

Table 3-3. 1280 Input Data Format
NOTE: See Section 3.1.1 for BYTE swapping parameters.

Command number
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.
Status Data
Indicator status data is returned in the second word (Table 3-4).
Batch commands return batch status in place of the low byte (Table 3-5 on page 17).

Setpoint commands return batch status in the low byte of the status word and the setpoint number in the high byte.

Table 3-5. Batch Function Status Data Format

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.
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

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
