Purchase now: Allen Bradley 1747-M13 64K Memory Module
Purchase now: Atlantechdrives provides you the 1747-M13, the highest-capacity memory backup module engineered by Allen Bradley specifically for the advanced SLC 500 processor lineup. In large-scale industrial manufacturing, losing a complex PLC program due to a simple power outage and a dead lithium battery can result in days of catastrophic downtime. The 1747-M13 mitigates this massive risk by providing 64 Kilobytes (64K) of non-volatile Flash EPROM storage. Designed to plug directly into the motherboard socket of the SLC 5/03, 5/04, and 5/05 CPUs, this module allows automation engineers to «burn» a permanent, battery-less backup of their finalized ladder logic, data tables, and communication configurations directly onto the silicon chip.
Technical Specifications of the 1747-M13
The 1747-M13 utilizes Flash technology, allowing it to be erased and rewritten multiple times via software without needing a UV light eraser. It provides enough capacity to back up the largest programs the SLC platform can handle.

- Compatible Processors: SLC 5/03 (L53x), 5/04 (L54x), 5/05 (L55x)
- Storage Capacity: 64K Words (Instructions and Data)
- Memory Technology: Flash EPROM (Non-volatile, battery-less)
- Primary Function: Permanent program retention and auto-recovery
Expert Tips: The Auto-Load Configuration
Simply inserting the 1747-M13 into your processor does not automatically protect your factory; it requires specific software configuration. Expert Tip: After burning your final program to the module using RSLogix 500, you must configure the processor’s internal Status File (S:1) to dictate its boot behavior. The most critical setting for plant maintenance is changing the S:1/10 bit to 1 (Load Memory Module on Memory Error). With this bit activated, if the machine is powered off and the internal RAM battery dies, the processor will detect the RAM fault on the next boot, automatically pull the pristine 64K program from the 1747-M13 back into RAM, and silently enter RUN mode. This auto-recovery feature instantly restores production without requiring a technician to connect a laptop.
Installation Advice: Static Protection
The 1747-M13 is a highly sensitive microelectronic component. You must completely power down the SLC chassis and remove the CPU module before installation. Use a grounded anti-static wrist strap to prevent electrostatic discharge (ESD) from frying the chip. Align the physical notch on the memory module with the corresponding printed notch on the processor’s socket to ensure proper orientation before pressing it firmly into place.
Frequently Asked Questions (FAQs)
Q: Will the 1747-M13 work in an older SLC 5/01 or 5/02 processor?
A: No. The physical socket and memory architecture of the 5/01 and 5/02 are completely different. For those legacy processors, you must use the smaller 1747-M1, M2, or M3 modules.
Q: Can I use this 64K module in a 16K or 32K processor?
A: Yes! The 1747-M13 is fully backward compatible with lower-memory processors in the 5/03, 5/04, and 5/05 families. It will simply utilize a portion of its available capacity to store the smaller program.
