Allen Bradley : SLC system
System Components:
A modular-hardware SLC / 1746 control system at minimum consists of a processor module and I/O modules in a single 1746 chassis with a power supply. The 1746 power supply connects to the left end of each 1746 chassis. You can configure a system with one, two, or three local chassis, for a total of 30 local I/O or communication modules maximum. 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 must add an I/O scanner module for ControlNet, DeviceNet, or Universal Remote I/O port.
Depending on the communication ports available on your particular SLC control system, you can select operator interfaces that are compatible with those particular ports.

Product Design : CPU
SLC 500 processors are available in a large range of forcible I/O (4096 inputs plus 4096 outputs maximum) and maximum user memory (1K instructions through 64K words). Several modular processors are capable of controlling remotely located I/O. By adding an I/O scanner module, you can use these processors to monitor/control these remotely located I/O across ControlNet, DeviceNet, and Universal Remote I/O links.
The 1746/1747 platform provides a modular-hardware system for maximum flexibility. SLC 500 processors are single-slot modules that you place into the left-most slot of a 1746 I/O chassis. For 1746 I/O in a location remote from the processor, the I/O adapter is a single-slot module that you place into the left-most slot of a 1746 I/O chassis.
The 1746 I/O chassis are built for back-panel mounting. The 1746 I/O chassis is available in sizes of 4, 7, 10, or 13 module slots. The 1746 I/O modules are available in densities of a maximum of 32 I/O per module.
You can configure a system with one, two, or three local chassis, for a total of 30 local I/O or communication modules maximum. You connect multiple local chassis together with chassis interconnect cables to extend the backplane signal lines from one chassis to another. This same 30-I/O-module limit applies to a chassis remote from the processor with an I/O adapter module in the first slot. Modules slide easily into chassis slots; no tools are required for module installation.
For many modules, because you wire to a removable terminal block that unplugs from the module, you do not need to disconnect wiring to replace an I/O module.
