Introduction to Controllogix

The ControlLogix System

The ControlLogix system is chassis-based and provides the option to configure a

control system that uses sequential, process, motion, and drive control in addition

to communication and I/O capabilities.

Configuration Options

There are 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 may be used in one ControlLogix

chassis. For example, for better performance, multiple controllers can be used in

motion applications.

Multiple Devices Connected via Multiple Networks

For some applications, a variety of devices may be connected to the ControlLogix

chassis via multiple communication networks. For example, a system might be

connected to the following:

• Distributed I/O via an Ethernet network

• A PowerFlex drive connected via a DeviceNet network

• Flowmeters connected via HART connection
