The Allen Bradley 1747-DU501 SLC 5/05 Firmware Upgrade Kit is a dedicated firmware maintenance accessory for the SLC 5/05 programmable logic controller family. It provides the materials and instructions required to perform a firmware/operating-system upgrade using Rockwell Automation's ControlFLASH procedure.
Unlike the SLC 5/03 and SLC 5/04 platforms, which use separate firmware upgrade hardware, the SLC 5/05 uses flash memory for its operating system. The 1747-DU501 kit is designed to support this upgrade process for compatible SLC 5/05 processors, including the 1747-L551, 1747-L552, and 1747-L553 models.
The kit is particularly relevant to facilities maintaining legacy SLC 500 automation systems. Updating controller firmware may provide access to supported functional enhancements and help maintain compatibility with the requirements of an existing control system.
Before performing an upgrade, technicians should verify processor compatibility, record the installed firmware revision, and create a complete backup of the user program and controller configuration. Firmware servicing should follow the manufacturer's installation instructions to avoid data loss or interruption to the control system.

Applications
The Allen Bradley 1747-DU501 SLC 5/05 Firmware Upgrade Kit is intended for firmware-related maintenance of compatible Allen Bradley SLC 5/05 programmable controllers. Firmware is the embedded software that manages the controller's internal operation, communication functions, and interaction with the control system.
This type of upgrade kit is relevant to industrial maintenance and system support activities where a controller's firmware must be updated or restored using an approved procedure.
Typical applications include:
PLC maintenance: Support firmware servicing on compatible SLC 5/05 controllers.
Control system upgrades: Assist with planned firmware maintenance during automation system updates.
Equipment refurbishment: Support controller servicing as part of industrial equipment refurbishment.
Spare-parts management: Provide a dedicated maintenance accessory for facilities operating SLC 5/05 hardware.
System troubleshooting: Support firmware-related maintenance when the controller's documented service procedure calls for an approved upgrade kit.
Before use, confirm that the kit is intended for the exact SLC 5/05 catalog number and firmware revision involved.
Advantages
Dedicated Firmware Maintenance Accessory
The 1747-DU501 is designed for firmware upgrade-related work rather than general PLC programming. Using the correct accessory helps keep maintenance procedures aligned with the controller manufacturer's requirements.
Support for SLC 5/05 Controller Servicing
It is associated with the SLC 5/05 controller platform, helping maintenance teams manage firmware-related service tasks on compatible equipment.
Useful for Legacy Automation Systems
Many industrial facilities continue to operate SLC 500 control systems. Having the correct maintenance accessories can support planned servicing and reduce avoidable delays during controller maintenance.
Compact Service Component
Its small form factor makes it convenient to store with PLC maintenance tools and spare parts.
Supports Controlled Maintenance Procedures
Firmware work should be performed using the correct documentation, compatible hardware, and approved firmware files. This helps reduce the risk of interrupted upgrades or controller incompatibility.
Technical FAQs
Q1: What is the Allen Bradley 1747-DU501 used for?
The 1747-DU501 is identified as an SLC 5/05 firmware upgrade kit. It is intended for firmware-related servicing of compatible SLC 5/05 programmable controllers.
Q2: Is the 1747-DU501 a PLC processor?
No. It is an upgrade accessory, not an SLC 5/05 CPU or processor module. The controller itself performs the PLC logic execution and system control functions.
Q3: Can this kit be used with every SLC 500 processor?
Compatibility should not be assumed across the entire SLC 500 family. Confirm the supported controller catalog numbers and firmware revisions before using the kit.
Q4: Does a firmware upgrade change the PLC application program?
Firmware and the user application program are different. Firmware updates the controller's embedded operating software, while the application program contains the logic and configuration created for the machine or process. Back up the application before carrying out firmware-related work.
Q5: Should the existing PLC program be backed up before an upgrade?
Yes. A verified backup of the user program and relevant controller configuration should be made before maintenance. Also record the existing firmware revision and communication settings.
Q6: Can the controller remain powered during firmware servicing?
Follow the specific upgrade procedure supplied for the kit and controller. Do not disconnect power or interrupt the process unless the documented procedure explicitly requires it.
Q7: How can the current SLC 5/05 firmware revision be identified?
The revision can generally be checked through supported programming software or controller diagnostic information. The exact method depends on the controller hardware and software version.
Q8: What problems can occur if an incompatible firmware file is used?
An incompatible firmware file may prevent the upgrade from completing or leave the controller unable to operate correctly. Verify the processor catalog number, hardware series, and supported firmware revision before starting.
Q9: Is the 1747-DU501 used for routine PLC program downloads?
It should not be treated as a general programming cable or routine program-download tool. Its stated purpose is firmware upgrade-related maintenance; use the appropriate programming interface for normal PLC programming.
Q10: What should be checked before ordering this upgrade kit?
Verify the exact kit catalog number, the SLC 5/05 processor model, the current firmware revision, and the intended upgrade procedure. Confirm that the kit is complete and suitable for the specific maintenance requirement.
