Preface

About This User Manual

Introduction

This manual applies to both the 1784-PCIDS and 1784-CPCIDS

communication interface cards. These cards provide DeviceNet

configuration and I/O scan capabilities and are functionally

equivalent. In the screen shots and examples in this manual, we

reference the 1784-PCIDS scanner, but understand that the

1784-CPCIDS scanner can be used in the same way.

This manual provides an example network that demonstrates how to

configure a DeviceNet network using the 1784-PCIDS card and

RSNetWorx for DeviceNet™software.

This manual describes how:

•to install and configure your 1784-PCIDS card

•to configure the DeviceNet network and map I/O data using

RSNetWorx for DeviceNet software

•to test and verify your DeviceNet network

This manual is designed to provide you enough information to get the

example network up and running. Use this manual if you are

knowledgeable about DeviceNet networks, but may not have

experience interfacing them to PCI- or CPCI-bus computers. The

information provided is a base; modify or expand the examples to suit

your particular needs.

Audience

This manual is intended for control engineers and technicians who are

installing, programming, and maintaining a control system that

includes communicating with a DeviceNet network using a PCI-bus

computer through a 1784-PCIDS card or using a compact PCI-bus

computer through a 1784-CPCIDS card.

We assume that you:

•are developing a DeviceNet network using a personal computer

in conjunction with a 1784-PCIDS, -CPCIDS card

•know each of your device’s I/O parameters and requirements

•are experienced with the Microsoft®Windows™environment

•are familiar with RSNetWorx for DeviceNet software

P-2 About This User Manual

The Example Network

This manual describes how to set up an example network. The

manual provides examples of each step of the setup, with references

to other manuals for more details.

System Components

We used the following devices and software for the example network

in this manual. For your own application, substitute your own devices

to fit your needs. The recommended configurations in this user

manual will help you set up the test system and get it working. Your

eventual configuration will depend on your application.

Note: If you use different software versions of these products some of

your screens may appear different from those shown in the examples.

Common Techniques

Used in This Manual

The following conventions are used throughout this manual:

•Bulleted lists provide information, not procedural steps.

•Numbered lists provide sequential steps.

•Information in bold contained within text identifies menu

windows, or screen options, screen names and areas of the

screen, such as dialog boxes, status bars, radio buttons and

parameters.

TIP This symbol identifies helpful tips.

A definition box defines terms that may be

unfamiliar to you.

Screen captures are pictures of the software’s

actual screens. The names of screen buttons and

fields are often in bold in the text of a procedure.

Pictures of keys represent the actual keys you

press.

This is a definition

box. When a word is

bold within the text

of a paragraph, a

definition box will

appear in the left

margin to further

define the text.

About This User Manual P-5

Terminology

This term Means

Change of State A type of I/O data communication. The scanner module can send and

receive data with slave devices that have the change of state feature.

Data is sent either whenever a data change occurs, or at the rate of the

heartbeat if no data has changed.

Cyclic A type of I/O data communication. The scanner can send and receive data

with slave devices that have the cyclic feature. Data is only sent at a

user-configurable rate.

Dual Mode The scanner is in dual mode when it serves as a master to one or more

slaves and as a slave to another master simultaneously.

EDS Electronic Data Sheet. A vendor-supplied template that specifies how

information is displayed as well as what is an appropriate entry (value).

EPR Expected Packet Rate. One quarter of the time in milliseconds that the

scanner must wait to hear from a device before deciding the connection

has failed.

Explicit

Messaging

Messaging protocol that states the meaning of the message. This

protocol commands the performance of a particular task and returns the

results of the task performance to the requestor. Used for lower priority

tasks, such as configuration and data monitoring.

Heartbeat Rate This only applies to change of state messaging.

Devices that are configured for change of state data also send a

“heartbeat” signal to indicate the device is still operating on the network

even if no data has changed.

Host Platform The computer in which the 1784-family scanner is installed.

I/O An abbreviation for “input and output.”

Implicit

Messaging

The type of messaging used for high priority I/O control data; e.g., change

of state, cyclic, polled, or strobed.

Input Data Data produced by a DeviceNet device and collected by the scanner for a

host platform to read.

MAC ID The network address of a DeviceNet node.

Network The DeviceNet network or the RSNetWorx for DeviceNet software

representation of the network.

Node Hardware that is assigned a single address on the network (also referred

to as device).

Offline When the RSNetWorx is not communicating on the network.

Online When RSNetWorx is configured and enabled to communicate on the

network.

Output Data Data that is produced by a host application and written to the scanner’s

memory. This data is sent by the scanner to DeviceNet devices.

PC Abbreviation for an IBM®compatible personal-computer.

Polled A type of input/output-data communication. A polled message solicits a

response from a single, specified device on the network (a point-to-point

transfer of data).

Record The node address and channel-specific memory assigned in the scanner’s

non-volatile storage for a node in the scanlist.

Rx An abbreviation for “receive”.

Scanlist The list of devices (nodes) with which the scanner is configured to

exchange I/O data.

Scanner The function of the 1784-family scanner to support the exchange of I/O

with slave modules.

Slave Mode The scanner is in slave mode when it is placed in another module’s

scanlist as a slave device. This is used to share data between scanners.

Strobed A type of I/O data communication. A strobed message solicits a response

from each strobed device (a multicast transfer). It is a 64-bit message that

contains one bit for each device on the network.

Tx An abbreviation for “transmit”.
