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.

steady - indicator is on continuously in the defined state.
alternating - the two indicators alternate between the two defined states at the same time (applies to
both indicators
viewed together ); the two indicators are always in opposite states, out of phase.
flashing - the indicator alternates between the two defined states (applies to each indicator
viewed
independent
of the other); if both indicators are flashing, they flash together, in phase.
2. SMAX is the highest node address on a ControlNet network that can transmit scheduled data.

Location Approval, when operating in hazardous locations:
Products marked “CL I, DIV 2, GP A, B, C, D” are suitable for use in Class I Division
2 Groups A, B, C, D, Hazardous Locations and nonhazardous locations only. Each
product is supplied with markings on the rating nameplate indicating the hazardous
location temperature code. When combining products within a system, the most
adverse temperature code (lowest “T” number) may be used to help determine the
overall temperature code of the system. Combinations of equipment in your system
are subject to investigation by the local Authority Having Jurisdiction at the time of
installation.
WARNING
!
EXPLOSION HAZARD -
•Do not disconnect equipment unless power has been
removed or the area is known to be nonhazardous.
•Do not disconnect connections to this equipment unless
power has been removed or the area is known to be
