A-B 1747-SDN SLC 500 DeviceNet Scanner Module System Components

The Example Application

This manual describes how to set up an example application. 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

application. 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.

The 1747-SDN module communicates with DeviceNet devices over

the network to:

• read inputs from a device.

• write outputs to a device.

• download configuration data.

• monitor a device’s operational status.

The 1747-SDN module communicates with the processor in the form

of M1/M0 File Transfers and/or Discrete I/O. Information exchanged

includes the following:

• Device I/O data

• Status information

• Configuration data

A processor to I/O DeviceNet configuration is shown in the following

figure. See the referenced chapters for more information.

A-B 1747-DCM Direct Communication Module DIP Switch 1 Settings

DIP Switch 1 Settings

Chassis Address (SW1-1 through SW1-6)

The chassis address refers to the logical chassis number from the scanner image

that contains a particular 1747-DCM’s image.

The table on the following page shows the settings that define possible chassis

address choices for all scanners. To use this table, first determine which of the

following categories applies to your scanner.

• PLC-2, mini-PLCs, PLC-2/30 with 1770-SD, SD2 remote scanner

• PLC-3 and PLC-5/250 processors (This category includes those with built-in

scanners, as well as the following, without built-in scanners: 1775-54A, -54B,

-S5, SR, -SR5, and 5250-RS.)

• SLC-5/02 (or above) with 1747-SN scanner

After determining which category applies to your 1747-DCM application:

1. Find the column for the scanner used in your application.

2. Go down the column to the chassis address that you assigned to the

1747-DCM.

3. Use the switch settings in the right-most columns of the table that

correspond to your chassis address.

A-B 1747-DCM Direct Communication Module Hardware Features DIP Switches

DIP Switches

DIP switches enable the 1747-DCM to properly interpret the RIO system addressing.

The 1747-DCM has two banks of DIP switches mounted on its circuit board. Each

bank contains eight switches. The default settings are shown below.

A-B 1747-AENTR SLC 500 EtherNet/IP Adapter Industrial Protocol

Use of the Common

Industrial Protocol (CIP)

The adapter uses the Common Industrial Protocol (CIP), the application layer

protocol specified for EtherNet/IP, the Ethernet Industrial Protocol. It is a

message-based protocol that implements a relative path to send a message

from the producing device in a system to the consuming devices.

The producing device contains the path information that steers the message

along the proper route to reach its consumers. Since the producing device

holds this information, other devices along the path simply pass this

information; they do not store it.

This has the following significant benefits:

• You do not need to configure routing tables in the bridging modules,

which greatly simplifies maintenance and module replacement.

• You maintain full control over the route taken by each message, which

enables you to select alternative paths for the same end device.

A-B 1747-AENTR SLC 500 EtherNet/IP Adapter in a Logix System

The 1747-AENTR in a Logix System

In this example, the I/O modules communicate with the controller through the

1747-AENTR adapter. The controller can produce and consume tags to the I/O.

Configuration of devices and the network is done through the personal

computer running the controller and configuration software.

Diagnostic Indicators The module has the following diagnostic indicators:

• Link 1 and Link 2 status indicator

• Module indicator

• 4-character status display

What the Adapter Does The 1747-AENTR EtherNet/IP adapter performs the following primary tasks:

• Control of real-time I/O data (also known as implicit messaging) – the

adapter serves as a bridge between I/O modules and the network

• Support of messaging data for configuration and programming

IC697ALG230 Base Converter Module Expansion Bus sampling technique

This sampling technique continues until all available

expander channels (16 x number of Expander mod

ules) have been scanned, at which time the sequence

starts over.  The number of analog scans required to

include sampling of all expander channels is equal to

the total number of Expander modules x 16 (16 chan

nels per Expander module) in the system.

With no Expander modules present, each base con

verter channel is updated once every 2.4 milliseconds.

With one or more Expander modules present, this

update time increases to 2.8 milliseconds.

Each expander channel is updated every 2.8 x N ms

(where N = total number of Expander channels pres

ent).  Note that the scan sequence is free running and

it cannot be synchronized with any external event.

Also note that all inputs of an Expander module will be

scanned even if they are not being used.

IC697ALG230 Base Converter Module Input Sampling Techniques

Input Sampling Techniques

The objective of the input sampling technique for the

analog subsystem is to provide 8 input channels on

the base module that have a fast (approximately 3 ms)

update rate and additional expander channels that are

updated less frequently, but have a lower cost per

channel.

Operation is such that the base module initially up

dates all eight channels plus one expander channel.

On each successive scan all eight channels of the base

converter are again updated – plus the next expander

channel in sequence.  After 16 analog input scans all 16

channels of the first expander have been sampled; on

the next scan, all eight base converter channels plus

the first channel of the next Expander module are

scanned.

IC697ALG230 Base Converter Module Expansion Bus

Expansion Bus

The bottom six terminals (35 through 40) on the ter

minal board on the Base Converter and Expander

modules make up an expansion bus for connecting

input Expander modules to the Base Converter mod

ule.  An analog multiplexer on the Expander module

acts as a switching circuit to connect analog inputs,

one at a time, to the A/D (Analog to Digital) converter

on the Base Converter module.

Each expander channel is updated every 2.8 x N ms

(where N = total number of Expander channels pres

ent).  Note that the scan sequence is free running and

it cannot be synchronized with any external event.

Also note that all inputs of an Expander module will be

scanned even if they are not being used.
