Allen-Bradley’s 4100-234-R compact motion controller is a microprocessor-based motion controller

with 4-axis and remote I/O options, but no axle-link option.

It uses an Intel i960 microprocessor with a 16MHz processor speed and an efficient multitasking

operating system (up to 10 tasks at a time) that allows up to 2.000 user-valued processes to be

stored as 16-bit floating-point numbers in write-protected battery-supported volatile memory.

It has 10 years of battery life and data retention. The 4100-234-R uses an I/O input power supply

in the input voltage range of 90 to 132 volts AC (47 to 63 Hz), 3 amps of current, 

and 5 to 40 volts DC (nominal 24 volts), with a maximum current of 3 amps and coupling of 3 amps.

1/4 x 11/4 ratio slow fuse. Its remote I/O option allows smooth and easy communication

with the device via a remote I/O adapter.

The 4100-234-R also allows direct connection to a programmable logic controller (PLC) using

modules and discrete transmissions. It has four isolated configurable analog outputs with

a control resolution of 6 bits, 305 µV, an output range of ±10 V DC or ±150 mA,

and a maximum offset voltage output of ±80 mV at 220Ω voltage resistance.

The 4100-234-R, when combined with the flex I/O module, provides wider discrete I/O input and output capabilities.

The 4100-234-R can connect up to eight flex I/O modules, providing a total of 128 discrete I/O points.

These discrete modules provide up to 20 dedicated optical isolated discrete inputs and

8 optical isolated open relay discrete outputs for the 4100-234-R.

The 4100-234-R uses GML for programming and RS-232C for file transfer.

ControlLogix® digital I/O modules are input and output modules that provide

On/Off detection and actuation. By using the producer/consumer network

model, digital I/O modules can produce information when needed while

providing additional system functions.

I/O modules in a ControlLogix system can be owned by a Logix5000™

controller. An owner-controller fulfills these functions:

• Stores configuration data for every module that it owns

• Sends I/O modules configuration data to define module behavior and

begin module operation with the control system

• Resides in a local or remote chassis in regard to the I/O module position

Each ControlLogix I/O module must continuously maintain communication

with its owner-controller to operate normally.

Typically, each module in the system has only one owner-controller.

Input modules can have more than one owner-controller.

Output modules, however,are limited to a single owner-controller.

The ControlLogix controller is part of the Logix 5000™ family of controllers.

• ControlLogix controllers can monitor and control I/O across the ControlLogix backplane, and over I/O links.

ControlLogix controllers can communicate over EtherNet/IP, ControlNet, DeviceNet, DH+™,

Remote I/O, and RS-232-C (DF1/DH-485 protocol) networks and many third-party process and device networks.

• The controller can be placed into any slot of a ControlLogix chassis and

multiple controllers can be installed in the same chassis.

Multiple controllers in the same chassis communicate with each other over

the backplane (just as controllers can communicate over networks) but operate independently.

• To provide communication for a ControlLogix 5570 controller,

install the appropriate communication interface module into the chassis.

ControlLogix 5580 controllers have a built-in EtherNet/IP port.

ControlLogix System Overview

The ControlLogix system provides discrete, drives, motion, process,

and safety control together with communication and state-of-the-art I/O in a small, cost-competitive package. 

The system is modular, so you can design, build, and modify it efficiently with significant

savings in training and engineering. A simple ControlLogix system consists

of a standalone controller and I/O modules in one chassis.

For a more comprehensive system, use the following:

• Multiple controllers in one chassis

• Multiple controllers joined across networks

• I/O in multiple platforms that are distributed in many locations and connected over multiple I/O links

• Select ControlLogix products are available with a conformal coating that adds a layer

of protection when exposed to harsh, corrosive environments.

Products with a conformal coating have a ‘K’ suffix at the end of the catalog number. 

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.

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.

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.
