Prepare for Module Installation

Before you install your module, you need the following items:

Before you install the module, you must know how to:

•program and operate an Allen-Bradley SLC 500 programmable

controller

•install and configure the devices on your ControlNet network

Make Sure That Your Processor and Scanner Are Compatible

The 1747-SCNR Scanner module fits in any slot of the chassis except

for the left-most slot of the first chassis, which is reserved for the

SLC 500 processor.

Select the ControlNet Node Address

Select the ControlNet node address of the 1747-SCNR by setting the

two 10-digit rotary switches on the top of the scanner. Valid switch

settings range from 01 through 99. Zero (00) is not a valid node

address.

Important: Since 00 is the default value from manufacturing, you

must change the default value when using the

scanner for the first time.

Insert the 1747-SCNR Scanner Into the Chassis

To insert the 1747-SCNR Scanner into the SLC chassis:

1. Turn off the SLC chassis power supply.

Important: If you disconnect the ac power, you lose the chassis

ground. Electrostatic damage (ESD) protection is lost.

ATTENTION

Do not install the 1747-SCNR Scanner module with the

chassis power supply on. Installing the module with the

chassis power supply on may damage the module.

2. Select a slot for the module in the chassis. Choose any slot

except the left-most slot of the first chassis, which is reserved

for the SLC 500 processor.

3. Insert the module into the slot you have selected. We

recommend that you insert the 1747-SCNR Scanner as close to

the chassis power supply as possible.

4. Apply firm, even pressure to seat the module in the I/O

chassis backplane connectors.

5. Restore power to the SLC chassis.

Connect to a ControlNet Network

Connect the 1747-SCNR Scanner module to a ControlNet network

via a tap with a 1m (39.4 in.) drop cable.

Four Allen-Bradley ControlNet taps are available from Rockwell

Automation as shown below.

We recommend that you use a tap with a straight connector—

1786-TPS or 1786-TPYS—when you attach a ControlNet 1747-SCNR

Scanner to a ControlNet network.

Important: Allen-Bradley ControlNet taps contain passive

electronics and must be purchased from Rockwell

Automation for the network to function properly.

After terminating your network segments, connect your node to the

network.
