ControlLogix System and Controllers
ControlLogix System
The ControlLogix system is chassis-based and provides the option to configure a
control system that uses sequential, process, motion, drive control, and
communication and I/O capabilities.
Configuration Options
This section describes some of the many system configuration options that are
available with ControlLogix controllers.
Standalone Controller and I/O
One of the simplest ControlLogix configurations is a standalone controller with
I/O assembled in one chassis.

Multiple Controllers in One Chassis
For some applications, multiple controllers can be used in one ControlLogix
chassis. For example, for better performance, multiple controllers can be used in
motion applications.
