Product Overview

The Allen-Bradley 1747-M13 functions as a high-reliability, non-volatile Flash EEPROM memory module for the SLC 500 controller platform. This module provides 64 KB (64,000 words) of secure storage to safeguard user programs and data tables against unexpected data loss. It serves as a permanent firmware backup solution that executes automatically during power cycles or battery failures, eliminating costly system downtime and reprogramming requirements in industrial operations. We supply this product as 100% brand new, original factory hardware to guarantee maximum operational lifespan and total system compatibility.

Technical Specifications

The following table outlines the mechanical and electrical specifications for the 1747-M13 memory module:

Engineering Advantages

• Elimination of Battery-Dependent Downtime: Standard PLC memory relies on lithium batteries to maintain user programs during power outages. When these batteries fail, processors lose their logic files instantly. The 1747-M13 burning process permanently writes the ladder logic into non-volatile memory, allowing the processor to restore operation immediately upon power restoration without human intervention.

• Streamlined Maintenance and Hot-Swapping: By configuring the SLC processor to load from memory on power-up (using S:1/10 and S:1/11 status bits), maintenance teams can replace damaged CPU hardware without connecting a laptop or using RSLogix 500 software. The new processor simply pulls the master application directly from the 1747-M13 module.

• High Thermal Tolerance for Harsh Panels: The module supports stable operation up to 60 degrees C, preventing data corruption caused by localized heat buildup inside sealed electrical enclosures and control cabinets.

• Firmware and Data Protection: The physical EEPROM installation structure guards critical automation code against accidental overwrites, unauthorized remote program modifications, and electromagnetic interference (EMI) that occasionally corrupts standard volatile RAM.

FAQs

• Do I need any additional hardware to install the 1747-M13 module onto my SLC processor?

  Yes. The 1747-M13 requires a 1747-M15 Series B adapter socket to plug into the dedicated memory port on SLC 5/03, 5/04, and 5/05 modular processors. The module cannot seat directly into the processor board without this specific adapter.

• Will the 1747-M13 work with an SLC 5/01 or SLC 5/02 controller?

  No. The 1747-M13 module exclusively supports the memory architecture of the modular SLC 5/03, 5/04, and 5/05 processors. Fixed controllers and lower-tier modular processors utilize alternative memory architectures or different part numbers like the UVPROM modules.

• How does the controller handle data tables when loading the program from the Flash EEPROM?

  You can configure the system behavior through your RSLogix 500 programming software. The processor can load either the entire program along with the saved data table values, or it can update only the instruction logic while preserving existing recipe values and register states currently stored in the processor RAM.
