Chapter 1 1769 CompactLogix Controllers Overview
For a more flexible system, use:
• multiple controllers in a single chassis.
• multiple controllers joined across networks.
• I/O in multiple platforms that is distributed in many locations and
connected over multiple I/O links.
Figure 2 - CompactLogix System Overview
The CompactLogix controller, part of the Logix family of controllers, provides a
small, powerful, cost-effective system consisting of the following:
• RSLogix™ 5000 programming software
• Built-in communication ports for EtherNet/IP (1769-L32E and 1769-
L35E only) and ControlNet (1769-L32C and 1769-L35CR
only) networks
• A 1769-SDN communication interface module providing I/O control and
remote device configuration over DeviceNet
• A built-in serial port on every CompactLogix controller
• Compact I/O modules providing a compact, DIN-rail or panel-mounted
I/O system
