CompactLogix is designed to provide a Logix solution for medium applications. Typically these applications are machine-level control applications with I/O requirements, network connectivity, and motion control requirements. A simple system can consist of a standalone controller with a single bank of I/O modules and DeviceNet communication. In a more complex system, add other networks and motion control. Multiple controllers can communicate across networks and share data.

    Using CompactLogix controllers on EtherNet/IP or ControlNet networks, you have the means to cost-effectively integrate a simple machine or application into a plant-wide control system. For example, you can use a CompactLogix 1769-L35E controller to connect a suite of scalable products, such as the Allen-Bradley PanelView Plus operator interface, POINT I/O, and the PowerFlex 70 drive, for a full-scale integrated solution.
Both ends of the architecture provide a direct link from real-time production information to manufacturing quality or execution systems (and back again), providing a more accurate view of plant operations and more control options than ever before to achieve this integration.

     CompactLogix PLC to provide for low-to medium-sized applications, Logix solution. Typical applications include device-level control applications (only require a limited amount of input and output as well as limited communication requirements). Compactlogix 1769-L31 provides two serial communication interface. 1769-L32C and 1769-L35CR controller provides an integrated ControlNet communication port. 1769-L32E and 1769-L35E to provide an integrated Ethernet interface.  CompactLogix PLC system support: from the center CompactLogix controller via EtherNet / IP, control network equipment network to remotely control the input-output and field equipment, distributed control to achieve in different locations.
