Product Features
Allen Bradley 1756-L55M12 is designed with a 1756-M12 memory module for data and logic storage and can be expanded with a nonvolatile memory module to store programs, configurations, historical data, and more.
Allen Bradley 1756-L55M12 provides additional non-volatile storage expansion using CompactFlash cards (1784-CF64 / 128).
Allen Bradley 1756-L55M12 supports three operating modes like Program, Run, and Remote, which can be switched using a key switch or RSLogix 5000 software.
Allen Bradley 1756-L55M12 supports RIUP, allowing modules to be installed or removed while the rack is powered.
Allen Bradley 1756-L55M12 has multiple status indicator lights (RUN, I/O, FORCE, RS232, BAT, OK) providing insight into the controller's operating status.
Allen Bradley 1756-L55M12 supports fault diagnosis and clearance, capable of handling “major faults” (such as firmware incompatibility) and “unrecoverable faults” (such as hardware errors), and provides clear troubleshooting steps.
Product Working Principle
Allen Bradley 1756-L55M12 must first install the ControlLogix rack and power supply, then insert the controller into the rack rails and lock it in place.
It must connect the battery (1756-BA1) to maintain memory data (in case of power failure). Battery installation must distinguish between Series A/B models.
The memory board (1756-M12) must be installed after disconnecting the battery. Use a #2 Phillips screwdriver to remove the side cover and insert the board.
Control programs are written using RSLogix 5000 software, downloaded to the controller, and executed in Run mode to drive I/O devices.
Non-volatile memory (memory board or CF card) is used to store programs and configurations to prevent data loss during power outages. Status indicator lights provide real-time feedback on operational status (green indicates normal operation, red indicates a fault).
