Information About 1747-M11

The 1747-M11 is part of the Allen-Bradley SLC 500 family, designed as a removable EEPROM module to support program retention and portability across processors. It offers 32 KB of user memory backup and is supported by SLC 5/03, 5/04, and 5/05 processors, including models such as the 1747-L532, 1747-L541, 1747-L542, and 1747-L543. The module allows users to safeguard programs against power loss and provides a convenient method for transferring logic between processors. Compatibility depends on module series: Series A units install on SLC 5/03 Series A or B processors, while Series B units are used with SLC 5/03 OS302, SLC 5/04 OS401, and SLC 5/05 processors. The 1747-M15 memory module adapter is required for programming the EEPROM via a PROM programmer. With EEPROM technology, the 1747-M11 provides durable, non-volatile memory storage suitable for industrial automation systems.

Key Features:

  • Memory type: EEPROM-based module for non-volatile storage of controller programs.
  • Capacity: 32 KB memory, providing reliable program backup and transfer.
  • Compatibility: Works with SLC 5/03, 5/04, and 5/05 controllers; supports models including 1747-L532, L541, L542, and L543.
  • Series support: Series A for SLC 5/03 (Series A/B), Series B for SLC 5/03 OS302, 5/04 OS401, and 5/05 controllers.
  • Program retention: Maintains stored programs even during extended power loss.
  • Installation: Requires 1747-M15 adapter when using a PROM programmer for EEPROM programming.
  • Exclusions: Not compatible with 1746-BAS and 1746-BAST modules.
  • Application: Provides backup, portability, and secure storage of PLC programs in industrial automation.

The 1747-M11 delivers the reliability and precision required for program storage, transfer, and backup in Allen-Bradley SLC 500 controllers.

Frequently Asked Questions about 1747-M11
Question: What is the primary function of the 1747-M11 module?
Date Update:23/05/2025
Answer:

The Allen-Bradley 1747-M11 is a flash EEPROM memory module designed to store and retain user programs in SLC 500 processors. It ensures data backup even when power is removed, making it ideal for use in applications where consistent program retention is critical. This module allows for program upload/download between a processor and an external PROM programmer. It enhances the resilience and reliability of control systems.

Question: Can the module be installed while the system is powered on?
Date Update:23/05/2025
Answer:

No, the 1747-M11 must only be installed or removed while the controller is powered down. Inserting it under power may corrupt memory or damage the processor’s internal components. Always follow ESD safety practices when handling the memory module. Proper handling ensures long-term reliability of both the module and the CPU.

Question: Are there any modules that the 1747-M11 is not compatible with?
Date Update:23/05/2025
Answer:

Yes, the 1747-M11 is not compatible with the 1746-BAS and 1746-BAST modules. Attempting to use it with unsupported devices may lead to operational faults or communication failures. It is essential to check Rockwell documentation for exact compatibility to avoid misconfiguration. Incompatible installation may damage the module or processor.

Question: What is the memory capacity of the 1747-M11?
Date Update:23/05/2025
Answer:

The module offers 32KB of EEPROM memory and supports up to 64,000 words of user program data. It is capable of storing large logic programs including approximately 1,000 ladder instructions. This capacity is suitable for mid-sized to complex automation applications. The EEPROM architecture ensures data is preserved without battery support.

Question: Is the 1747-M11 still being manufactured?
Date Update:23/05/2025
Answer:

No, the 1747-M11 is classified as an obsolete product by Rockwell Automation. While it is no longer in active production, it may still be available through secondary markets or surplus distributors. For new projects, it is recommended to consider newer CompactLogix or ControlLogix platforms. Ensure lifecycle compatibility for spare parts planning.
