Version 20.12 is not just a minor bump. Rockwell addressed several significant issues that plagued earlier v20 revisions. If you are running any version lower than 20.12, you are exposing your system to known anomalies.
Any version 20.xx software on your PC can successfully communicate, upload, and download to a PLC running firmware 20.12. Critical Software Compatibility Guide
While v20 was a broad release, the .12 minor revision focused heavily on security and synchronization. Key highlights include:
When creating a new project:

⚠️ Firmware 20.12 is not compatible with Studio 5000. You must use RSLogix 5000 v20.01.00 (or later CPR 9 SR 5) .
The RSLogix 5000 firmware 20.12 represents a significant advancement in the capabilities and performance of Rockwell Automation's Logix5000 controllers. With its enhanced security features, improved performance, and advanced diagnostic capabilities, this firmware version offers substantial benefits for industrial automation applications. However, successful implementation requires careful planning, testing, and consideration of compatibility and system requirements. By understanding the features and benefits of firmware 20.12, users can make informed decisions about upgrading their control systems and taking full advantage of the latest technologies in industrial automation. rslogix 5000 firmware 20.12
[RSLogix 5000 v20.12] ---> The Bridge Release ---> [Studio 5000 v21+]
RSLogix 5000 firmware version 20.12 is a stable minor revision for the Logix 5000 platform, rooted in the feature-rich major version 20. While specific detailed release notes for this exact minor revision are not publicly available, understanding the major version's capabilities and the unique behavior of the 20.03 minor revision is critical. Always ensure that the of your programming software matches that of your controller firmware.
Rockwell identified a security vulnerability and a need for a more robust bootloader. Consequently, if you have a controller running older firmware (like v20.01 or earlier), you often cannot flash it directly to v20.12 using ControlFLASH. Version 20
If you are tasked with maintaining or recovering a system running Firmware 20.12, there are specific technical hurdles you will face today.
Rockwell Automation typically releases firmware versions to introduce new features or support new hardware. However, version 20.12 was primarily engineered as a stability, security, and hardware compatibility patch.
Open ControlFLASH or ControlFLASH Plus. Select the targeted controller over RSLinx via a stable USB or direct Ethernet connection. Avoid flashing over wireless networks or busy industrial routing infrastructure. Any version 20
Before upgrading to firmware 20.12, verify your hardware. Not all controllers support all firmware revisions.
