Remote I/O Adapter Module 3
1747-ASB Module Overview
The 1747-ASB module is an SLC 500 single-slot, RIO communication link module. It
occupies the first slot (slot 0) of a 1746 remote chassis, where the SLC processor
normally resides.
The 1747-ASB module is an adapter, or slave, on the RIO link, and the master of the
remote chassis and remote expansion chassis in which it is installed. Remote
expansion chassis are optional. The module acts as a gateway between the scanner
and the I/O modules residing in the remote chassis and remote expansion chassis.
It maps the image of the I/O modules in its remote chassis and remote expansion
chassis directly to the SLC or PLC processor image.
Output data is sent from the scanner of either the SLC or PLC local chassis to the
1747-ASB module across the RIO link. This data is automatically transferred to the
output modules across the chassis backplane by the 1747-ASB module. Inputs from
the input modules are collected via the backplane by the 1747-ASB module and
sent back to the scanner across the RIO link. No user programming of the 1747-ASB
module is necessary.

Required Tools and Equipment
Have the following tools and equipment ready:
• medium blade screwdriver
• (2) 1/2 watt terminating resistors (See page 18 for correct size.)
• an adequate length of RIO communication cable (Belden™ 9463) for your
specific application. (See page 18 for maximum cable distances.)
IMPORTANT :
Determining System Power Requirements
Review the power requirements of your system to ensure that the chassis supports
placement of the 1747-ASB module. The adapter consumes 600 mA at 5V dc. For a
detailed list of device load currents, refer to the SLC 500 Fixed Hardware Style
Installation and Operation Manual, publication number 1747-6.21; the SLC 500
Modular Hardware Style User Manual, publication number 1747-UM011, or the
appropriate Technical Data sheet.

Remote I/O Adapter Module 5
Slot Addressing
Slot Numbering
The 1747-ASB module is capable of controlling 30 slots. When expansion chassis
are used, the 1747-ASB module treats all of the I/O modules as if they are installed
in a single chassis.
The remote chassis and remote expansion chassis slots are numbered from 0 to 30.
The 1747-ASB module must reside in slot 0. Slots numbered 31 and above cannot
be used.
IMPORTANT
Installing modules in slot 31 or above results in a module error.
Addressing I/O Modules
SLC and PLC processors address the I/O modules residing in the chassis by logical
rack and logical group. Slot addressing refers to how each chassis slot is assigned a
specific amount of the 1747-ASB module image. The amount depends on which
type of slot addressing you choose; 2-slot, 1-slot, and 1/2-slot addressing is
available, as shown below.
IMPORTANT
Due to SLC and PLC addressing differences, when the 1747-ASB
module is used with an SLC processor, the image bit numbers are
0 to 7, 8 to 15 decimal. When the 1747-ASB module is used with
a PLC processor, the image bit numbers are 0 to 7, 10 to 17 octal.
