Product Description
The 1747-M2 is a 4KB non-volatile memory module for Allen-Bradley SLC 500 PLCs (both fixed and modular styles, including specific models like 1747-L30A/C, 1747-L40A/C, 1711-L511, 1747-L514, and 1747-L524). It protects the PLC program from data loss due to power outages, as the PLC's standard RAM memory is volatile and relies on a battery for retention. Handle the module carefully by its edges in a clean, oil-free environment to avoid electrostatic discharge damage. Ensure the PLC is powered off during installation/removal and follow the correct J1 jumper settings. CE marking indicates compliance with applicable directives.
Is Your Device Showing These Signs?
The Allen Bradley 1747-M2 memory module commonly experiences issues such as memory corruption leading to PLC faults and program loss. Resolve this by performing a memory clear and reloading the application program. Battery failures are frequent, causing data retention problems; replace the battery with a new, compatible unit. Intermittent communication errors arise from corroded or damaged pins on the module connector; clean or replace the connector to ensure proper communication with the PLC backplane. Firmware incompatibility can cause operational errors; update the firmware to the latest revision compatible with the PLC system.
