Product Description
The Allen-Bradley 1756-L55M22 ControlLogix Controller, part of the Logix5000 family, features dual CPUs (Logix and backplane) and ample memory (750 KB data/logic, 208 KB I/O, and integrated nonvolatile backup). The Logix CPU handles application code and messaging, while the backplane CPU manages backplane communication and I/O. It connects to workstations via a serial port using the 1756-CP3 cable and communicates with other devices through networks like Ethernet/IP, ControlNet, and DeviceNet, supporting system-shared tags. Its multitasking capabilities allow for efficient allocation of processing time, and it supports various Logix5000 programming languages both online and offline. Diagnostic features include an I/O LED for communication failure indication and a fault handler. The controller requires regular maintenance of its 1756-BA1 or 1756-BATM battery.
