Allen-Bradley 1747-OS302 Firmware Upgrade Kit

The Allen-Bradley 1747-OS302 Firmware Upgrade Kit is a field-installable upgrade package for SLC 5/03 processors in the SLC 500 family, designed to update the controller to the OS302 firmware revision (FRN-10) and to provide a supported path for bringing older installations up to the OS302 software stack. The kit targets SLC 5/03 controllers and, according to catalog literature, includes five upgrade labels plus the firmware media necessary to perform the OS302 upgrade in the field, along with documentation that guides technicians through the step-by-step upgrade process. It is intended for in-situ updates on active SLC 5/03 installations, allowing technicians and automation engineers to upgrade the processor’s operating system without altering existing I/O wiring or PLC logic, thereby preserving program structure while enabling compatibility with newer OS302 features. Cataloged as 1747-OS302 with FRN-10, this firmware upgrade kit is distributed through Rockwell Automation’s authorized channels and is commonly sourced from approved distributors, service partners, and legacy catalog resellers worldwide.
