SLC 500 System Overview
The Allen-Bradley SLC 500 is a small chassis-based family of programmable
controllers, discrete, analog, and specialty I/O, and peripheral devices. The SLC 500
family delivers power and flexibility with a wide range of communication
configurations, features, and memory options. The RSLogix 500 ladder logic
programming package provides flexible editors, point-and-click I/O configuration,
and a powerful database editor, as well as diagnostic and troubleshooting tools to
help you save project development time and maximize productivity.
Typical Systems With up to 64 K of configurable data/program memory available and over 60 types of
I/O modules, as well as a choice of networking options, the SLC system provides a
powerful solution for stand-alone or distributed industrial control.

Local Systems
At minimum, a modular hardware SLC 500 control system consists of a processor
module and I/O modules in a single 1746 chassis with a power supply.
Power Supply
Processor
I/O Modules
You can configure a system with one, two, or three local chassis, for a maximum total
of 30 local I/O or communication modules. You connect multiple local chassis
together with chassis interconnect cables to extend the backplane signal lines from
one chassis to another.

Choose the processor module with the on-board communication ports you need. You
optionally add modules to provide additional communication ports for the processor.
For I/O in locations remote from the processor, you can choose between a ControlNet,
DeviceNet, or Univeral I/O link. A communication interface module is required in
both the local and remote chassis.
Depending upon the communication ports available on your particular SLC control
system, you can select operator interfaces that are compatible.

Laying Out the System
Lay out the system by determining the amount of I/O necessary, the network
configurations, and the placement of components in each location. Decide at this time
whether each chassis will have it’s own controller or a networked solution.
SLC 500 processors are available with a large range of memory sizes (1 K through 64
K) and can control up to 4096 input and 4096 output signals. All modular processors
except the SLC 5/01 processor are capable of controlling remotely located I/O. By
adding an I/O scanner module, you can use these processors to control/monitor these
remotely located I/O across ControlNet, DeviceNet, and Universal Remote I/O links.
SLC 500 processors are single-slot modules that you place into the left-most slot of a
1746 I/O chassis. For I/O in a location remote from the processor, the I/O adapter is
a single-slot module that you place in the left-most slot of the I/O chassis. SLC 500
modular systems provide separate power supplies which must be mounted directly on
the left end of the 1746 I/O chassis.
The 1746 I/O chassis are designed for back-panel mounting and available in sizes of
4, 7, 10, or 13 module slots. The 1746 I/O modules are available in densities up to a
maximum of 32 channels per module.

Communications
Evaluate what communications need to occur. Knowing your communications
requirements will help you determine which processor and which communications
devices your application might require.
An SLC processor communicates across the 1746 backplane to 1746 I/O modules in
the same chassis in which the processor resides. Various models of SLC processors
have various on-board ports for communication with other processors or computers.
Also, separate modules are available to provide additional communication ports for
communication with other processors, computers, and remotely located I/O.
Each processor has one or two built-in ports for either EtherNet/IP, DH+, DH-485, or
RS-232 (DF1, ASCII, or DH-485 protocol) communication.
In addition to the on-board ports available with SLC processors, you have the option
of providing another communication port for an SLC processor by adding a
communication module.
Adapter modules for 1746 I/O are available for ControlNet and Universal Remote I/O
links. An I/O adapter module in a chassis with I/O modules interfaces the I/O modules
with the I/O link for communication with a scanner port for a processor at another
location.

Selecting SLC 500
I/O Modules
Step 1 - Select:
I/O modules - available in a variety
of densities and voltage options.
Some modules have diagnostic
features, individually isolated
inputs/outputs or electronic
protection.
interface modules (IFMs) or pre-
wired cables (optional)
Digital I/O modules, analog I/O modules, and specialty temperature, counting,
process control, and BASIC language modules are available to help you create a
custom solution for your application.
1746 Digital I/O
Modules
Digital I/O modules are available with 4, 8, 16, or 32 channels and in a wide variety of
I/O voltages (including AC, DC, and TTL). Combination modules with 2 inputs/2
outputs, 4 inputs/4 outputs, and 6 inputs/6 outputs are also available.
Terminals on the 4, 8, 12, and 16-channel modules have self-lifting pressure plates
that accept two 14 AWG (2 mm2) wires. LED indicators on the front of each module
display the status of each I/O point.
32-channel I/O modules are equipped with a 40-pin, MIL-C-83503 type header and a
removable wiring connector (1746-N3). The connector can be assembled with the
wire type and length of your choice.
Output modules are available with solid-state AC, solid-state DC, and relay contact type
outputs. High current solid-state output modules, catalog numbers 1746-OBP16, -
OVP16, and -OAP12, have fused commons with a blown fuse LED indication. The
1746-OB16E, -OB6EI, and -OB32E modules provide electronic protection from short
circuit and overload conditions.
Wiring of 16 and 32-channel modules can also be accomplished with a bulletin 1492
interface module and pre-wired cable. All 16-channel I/O modules and catalog
numbers 1746-OX8, -OBP8, -OAP12, 1746-IO12 are equipped with color-coded
