Physical Description
The MicroLogix 1100 is a compact, rectangular controller with an integrated terminal strip for I/O connections. The front panel includes status LEDs for power, fault, communication, and I/O states. An embedded LCD screen provides basic system information, IP address display, and simple configuration or troubleshooting functions. Ethernet and serial ports are accessible on the front or bottom edge depending on the model.
History
The MicroLogix 1100 was introduced as part of Rockwell Automation’s MicroLogix family to bridge the gap between the smaller MicroLogix 1000 and the more capable MicroLogix 1200/1400 controllers. It was one of the first controllers in its class to include built-in Ethernet, making it popular for networked machine control without requiring additional communication modules.
The platform gained widespread use in OEM equipment and small industrial systems due to its balance of cost, functionality, and ease of programming. It has since been gradually phased out in favor of newer platforms such as the Micro800 series, though it remains in service in many legacy installations.
