About This Manual

WARNING

This manual provides information needed to install and use the Rice Lake Weighing

Systems EtherNet/IP

™

Interface. The EtherNet/IP Interface allows the indicator to

communicate with an EtherNet/IP network.
See the indicator installation manual for additional installation information and

detailed descriptions of indicator functions.
The EtherNet/IP Interface is installed inside the indicator enclosure. Installation in

NEMA 4X stainless steel enclosures permits use in washdown environments.

Some procedures described in this manual require work inside the
indicator enclosure. These procedures are to be performed by
qualified service personnel only.

The Ethernet card should NOT be used to communicate between buildings. The
Ethernet port is not suitable for connection to circuits used outside the building
and is subject to lightning or power faults.

1.0 Introduction

EtherNet/IP (“Ethernet Industrial Protocol”) is an open industrial networking
standard that allows control applications to make use of widely-available Ethernet
communications components and physical media. EtherNet/IP is based on the IEEE

802.3 Ethernet standard, the TCP/IP protocol suite, and CIP
Protocol), the real-time I/O and information protocol used by both DeviceNet

networks.

The EtherNet/IP Interface returns weight and status inform ation from an indicator to
the network and provides limited control of indicator functions to the programmer.
Indicator configuration and calibration cannot be performed through the EtherNet/IP
Interface.

EtherNet/IP-specific functions are provided by an EtherNet/IP 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 EtherNet/IP Interface module.

This section describes the procedures used to install the EtherNet/IP Interface into the
indicator.

2.1 Installing the EtherNet/IP Interface

12 EtherNet/IP Installation and Programming Manual

4.0 Commands

Note

Note

Commands are used by the master device to send and receive data from the interface
as integer or floating-point data. The master sends eight bytes in the outpu t 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.

4.1 Output Data Format

To perform a command, the master uses the output command format to send four 16­bit 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 4-1.

Word Description

Word 1 Command number

Word 2 Parameter

Word 3 Value (MSW)

Word 4 Value (LSW)

Table 4-1. Output Data Format

See Section 4.1.1 for BYTE swapping parameters.

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 4-2
lists the commands that can be specified for indicators. Some commands may not be
available on all indicators.

A lockout feature that looks for any change in the output format data is
incorporated into the indicator receive mechanism to prevent inundation
by the same command (affected commands noted in Table 4-1).
Repeated commands must be separated by any other valid command/
parameter/value combination.

Parameter value

Note

Note

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 4.3 on page 18 for specific command requiremen ts.

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.

4.1.1 BYTE Swapping

See the Ports Menu in the 880 Technical/Service manual (PN 158387)

The 880 indicator sends out and receives data in integer format.
The standard format would be as follows for all input and output values:

High BYTE – Low BYTE

If the Parameter in the 880 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 your PLC,

either swap the BYTES in your PLC or change the SWAP parameter to YES.

4.2 Input Data Format

In response to a command, the 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 4-3.

The value type can be set for those commands that do not specify integer or floating
point data by sending a command 0x000 to specify integer dat a or command 0x100
for floating-point data. The value type is returned in the status word (bit 14) of the
input format.

Word Description

Word 1 Command number

Word 2 Status

Word 3 Value (MSW)

Word 4 Value (LSW)

Table 4-3. Input Data Format

See Section 4.1.1 for BYTE swapping parameters.

4.2.1 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.

Commands 15

4.2.2 Status Data

Note

Indicator status data is returned in the second word (see Table 4-4). Batch com mands
return batch status in place of the low byte (see Table 4-5). Setpoint commands return
batch status in the low byte of the status word and the setpoint number in the high
byte.

4.2.3 Value

Weight data is returned to the master in the third and fourth words of the input
command format, depending on the command and the value type. The weight da ta
returned is the displayed weight after the command is executed, unless the command
specifies otherwise.

4.2.4 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.

The following is what is needed in the output words to set the value of Setpoint #1 to

10000.

Command word = 304

Parameter word = 1

MSW = 17948

LSW = 16384

4.2.5 Reading a Float Value:

When a float value is read it will be retuned in two integers that will represent the
float value.

The PLC will need to combine MSW and LSW integer values back into a float value.
The following is what is will be 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
