IMPORTANT If you set the value of the adapter switch to 888 and then power cycle

the module, the following occurs:

• The DHCP Enabled function is enabled (set to True).

• The Ethernet link is negotiated automatically. The Auto Negotiate

function is set to True.

• The web server is enabled. The Disabled Web Server function is

disabled.

• The Ethernet ports are disabled. Both ports are re-enabled once the

switches are returned to their previous value and power is cycled.

Enable or Disable the Web Server

Enable Web Server in Static IP mode

1. Set the switches to 000 and cycle power to the adapter.

The module LED flashes red and the four-character status display scrolls

the message “Web Server Enabled”.

2. Set the switches to the desired IP address and cycle power to the adapter.

3. In your web browser, enter the IP address of the adapter.

The web server home page displays.

Disable Web Server in Static IP mode

1. Set the switches to 901 and cycle power to the adapter.

The module LED flashes red and the four-character status display scrolls

the message “Web Server Disabled”.

2. Set the switches to the desired IP address and cycle power to the adapter.

3. In your web browser, enter the IP address of the adapter.

The web server home page does not display.

The network address switches are set to 999 and DHCP enabled, by default.

You can set the network Internet Protocol (IP) address in the following ways:

• Use the network address switches on the module.

• Use a Dynamic Host Configuration Protocol (DHCP) server, such as

Rockwell Automation BootP/DHCP.

• Retrieve the IP address from nonvolatile memory.

The adapter reads the network address switches first to determine if the

switches are set to a valid number. You set the node address by using the

network address switches. Valid settings range from 001…254.

When the switches are set to a valid number, the adapter’s IP address is

192.168.1.xxx (where xxx represents the number set on the switches).

The adapter’s subnet mask is 255.255.255.0 and the gateway address is set to

0.0.0.0. The adapter does not have a host name assigned, or use any Domain

Name System when using the network address switch settings.

If the switches are set to an invalid number (for example, 000 or a value greater

than 254 excluding 888), the adapter checks to see if DHCP is enabled. Setting

the switches to 888 restores default factory settings.

Module Description

The 1747-AENTR Adapter enables CompactLogix™ and ControlLogix®

processors to control SLC™ I/O modules. It is primarily designed to enable

migration of existing SLC controlled systems to Logix-based systems.

The adapter mainly acts as a gateway between the SLC backplane and

EtherNet/IP and typically replaces an SLC controller in the 1746 rack. On

remote SLC racks, it replaces the 1747-ASB module or the ControlNet® adapters

1747-ACN15 and 1747-ACNR15.

Control of the backplane I/O is accomplished with a CompactLogix or

ControlLogix controller communicating through an EtherNet/IP router in the

Logix backplane, across EtherNet/IP, and into the 1747-AENTR gateway.

As a gateway between the SLC backplane and EtherNet/IP, the 1747-AENTR

module is a CIP™ server (for both Explicit Messaging and I/O) on the Ethernet

port, and an SLC host on the 1746 backplane.

You have a choice of three configurations to match your hydraulics:

• proportional amplifier with ramp and proportional valve

• servo amplifier with ramp and variable-volume pump

• Allen-Bradley 1305 Drive and hydraulic pump

You may use either of the following output voltage ranges:

• 0-10V dc for the Allen-Bradley 1305 Drive or variable-volume pump

• –10 to +10V dc for the proportional amplifier and proportional valve

Minimizing Interference

from Radiated Electrical

Noise

Important: Signals in this type of control system are very susceptible

to radiated electrical noise. The module is designed to set the loss-ofsensor

bit I:e.0/8 and the LDT-error bit I:e.0/0 when it detects position

values that are lost or corrupted by electrical noise.

Connect module output terminals to output devices with correct bonding:

• connect power supply output commons together

• electrically isolate power supply output commons from earth ground

• use bond wires that are equal in size to signal wires

Minimize interference from radiated electrical noise with correct

shielding and grounding:

• connect all of the following to earth ground:

– LDT flange, frame, and machine

– I/O chassis

– protective ground

– AC ground

– cable shields at one end only, preferably with 3/8” braid wire

(for analog output, ±15V dc PS, 24V dc PS, and LDT)

– terminal 4 of the input terminal block

• run shielded cables only in low-voltage conduit

• place the SLC-500 processor, power supply, and I/O chassis

assembly in a suitable enclosure

Connect the LDT to Module Inputs

We assume that you will use one of the following types of LDT:

• Temposonics II: RPM TTSRxxxxxxR, or

DPM TTSRxxxxxxDExxx

• Balluff: BTL-2-L2, or BTL-2-M2

• Santest: GYRP, or GYRG

• Gemco Quick-Stick II: 951VP, or 951 RS

Connect Module Outputs to Output Devices

Module outputs connect to a separate 2-conductor output terminal

block located beneath the input terminal block.

Note: Follow manufacturer recommendations for shielding the output

cables of the proportional amplifier. Typically, pulse-width modulated

outputs radiate electrical noise originating from the +24V dc power

supply, so isolate the shields of the amplifier output cable to a 0V dc

connection inside the proportional amplifier.

Why Use This System?

Because you can change the speed of the hydraulic ram with extend

and retract profiles and store additional profiles (recipes) in data

table iNteger (N) files, this control system has these benefits:

• reduced cycle time – you can increase ram speed for faster operation

• reduced or eliminated pressure spikes and water-hammering for

smoother operation and less wear and tear on the machine –

you can profile accelerations and decelerations of the hydraulic ram

• energy savings – you can match the speed of the hydraulic pump

to the force that you need

• faster new-part change-over – you can store your setups and

minimize mechanical re-adjustments between parts

How Does It Work?

The 1746-QV module executes the extend and retract profiles that you

load to control the motion of the hydraulic ram. You can program up

to seven different voltages over the length of travel in both the extend

and retract directions to control how the ram accelerates or decelerates.

Each position setpoint triggers a corresponding voltage output in the

range of –10V to +10V dc that translates into speed. The LDT

provides high-speed position updates to the module for consistent and

repeatable motion.

What Are Typical Applications?

Use the 1746-QV module in an SLC-based system for low-cost

control of:

• hydraulic machinery

• simple (non-CNC) hydraulic presses

• diecasting machinery

• welder placement

• pneumatic actuators for clamping or placement

In addition, the module is designed to support standard proportional

amplifiers and retrofit into most existing hydraulic systems.

What Is the 1746-QV Module?

The 1746-QV module is part of an SLC-based open-loop control

system for controlling the speed and placement of an hydraulic ram.

The module accepts an input from a linear displacement transducer

(LDT) and motion profiles that you program into the SLC processor,

and varies its output in the range of 10V dc. The SLC processor

sends to the module a pair of extend and retract profiles that define

when to accelerate or decelerate hydraulic motion.

What Is an SLC-500 System?

The Allen-Bradley Small Logic Controller (SLC) system is a

programmable control system with an SLC processor, I/O chassis

containing analog, digital, and/or special-purpose modules, and a

power supply. The 1746-QV module interfaces your hydraulic ram

and position-monitoring device (LDT) to the ladder sequence in your

SLC processor.
