CompactLogix System

Controller

CompactLogix controllers integrate easily with other members of the Logix family of controllers and are programmed using RSLogix 5000, just like other members of the Logix controller family. So, if you are also running ControlLogix, you can easily duplicate and scale existing programs to run on CompactLogix.

CompactLogix networked controllers integrate an EtherNet/IP or ControlNet connection and are designed to meet the challenged of demanding applications. The CompactLogix EtherNet/IP family of controllers includes the 1769-L23E, 1769-L35E and the 1769-L32E. The CompactLogix ControlNet family of controllers includes the 1769-L35CR and the 1769-L32C.

Standalone Controllers

CompactLogix is also ideal for systems that require standalone control. For cost-effective sequential and process machine control applications, consider the 1769-L23 family of packaged controllers or 1769-L31 controllers. For low-axis count motion control applications, consider the 1768-L43 (up to 4 axes) or the 1768-L45 (up to 8 axes).
