The Allen Bradley 1756-L72 is the standard controller in the ControlLogix family. Designed to be reliable and versatile, it can manage up to 32 independent tasks and support simultaneous execution. Each task can run up to 100 independent programs, providing exceptional flexibility for complex applications.
It supports 500 connections and offers a wide range of interfaces for various devices. Extensive communication options support Ethernet/IP, ControlNet, DeviceNet, and Data Highway Plus, as well as remote I/O and SynchLink communication. This broad compatibility enhances integration with existing systems. Furthermore, a USB port simplifies setup and data transfer, improving efficiency.
The 1756-L72 Allen Bradley ControlLogix 4 MB CPU controller module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 1756-L72 also emphasizes system reliability by providing complete redundancy support, ensuring continued operation in the event of a failure. This feature is especially important in environments where uptime is critical. In summary, the 1756-L72 controller stands out with its superior performance and extensive connectivity, meeting the needs of complex automation tasks.
The 1756-L72 chassis does not integrate Ethernet or serial ports. It bridges high-speed networks on the backplane by working with peripheral communication bridging modules, such as the 1756-EN2TR for EtherNet/IP, the 1756-CN2R for ControlNet, or the 1756-DNB for DeviceNet. This architecture, by combining two L72 CPUs with redundant 1756-RM2 modules located in different racks, enables millisecond-level seamless failover in critical factory environments.
