Allen-Bradley 1747-M11 SLC 500 Flash Memory Module
The Allen-Bradley 1747-M11 serves as the primary 1747-M11 Flash Memory Module utilized to execute permanent program storage and firmware backup across SLC 500 platforms. It provides non-volatile, solid-state memory backup for user programs and processor configurations, safeguarding ladder logic routines against total battery drain or electrical discharge events.
Hardware Specifications

Backplane Bus Velocity & Deterministic Network Execution
The 1747-M11 socket-mounted flash card integrates directly into the execution engine of SLC 500 processors without impacting backplane bus communication velocity. During power-up sequences, the module can automatically transfer stored ladder logic programs, system parameters, and network configurations directly to RAM, allowing processor nodes to join deterministic networks immediately upon restoration of line power. Non-volatile flash technology ensures that critical automation routines remain intact through extended power outages or field maintenance cycles.
Frequently Asked Questions
Q: Can the 1747-M11 memory module be installed or removed while the SLC 500 processor is powered?
A: No, primary power to the SLC 500 processor must be turned off before inserting or removing the memory module from the CPU socket to prevent damage to internal IC components.
Q: How is the program saved from the processor RAM into the 1747-M11 flash module?
A: Program transfer to the flash memory module is executed using Rockwell Software (RSLogix 500) by selecting the "EPROM/Flash Transfer" utility while connected online to the processor.
Field Installation Guidelines
- Anti-Static Handling: Handle the memory module in an ESD-safe workspace. Wear a grounded wrist strap before removing the 1747-M11 from its protective packaging or inserting it into the processor.
- Socket Insertion: Turn off main power to the SLC 500 chassis. Locate the memory socket on the CPU board, align the keyed pins of the 1747-M11 module, and press down evenly until seated firmly in the socket header.
- Boot Configuration: Set the CPU firmware parameters via RSLogix 500 to configure "Load Memory Module on Power-Up" or "Load on Error" based on system backup strategy requirements.
