Rslogix 5000 Firmware 20.12

Save a complete backup of the existing PLC program ( .ACD file). Step 1: Put the Controller in Program Mode

Go to Controller Properties in RSLogix 5000. Change the software revision to match v20.12. after flashing.

Version 20.12 sits at a crossroads. It supports many older modules (like the 1756-L61/L62 controllers) that newer firmware versions (v32+) have started to deprecate or limit. It serves as the last "modern" stop for aging hardware infrastructure.

Firmware v20.12 specifically addresses stability, security, and hardware compatibility. It ensures that older ControlLogix (L6) and early-generation L7 controllers can operate reliably in production environments without requiring expensive hardware upgrades.

Install the firmware kit on your PC. This adds the 20.12 files to your ControlFLASH directory.

For maintenance engineers, understanding v20.12 is not about learning new features—it is about respecting the stability of legacy systems and knowing how to navigate the quirks of older software in a modern IT environment. If your plant is running v20.12, rest assured: you are running one of the most robust iterations of the ControlLogix platform ever released—just make sure you keep that Windows 7 VM handy for troubleshooting.

While v20.012 is a firmware revision, it was primarily released to be used with RSLogix 5000 v20.01 . However, using v20.00 software with v20.012 firmware strongly discouraged

To upgrade a controller to v20.12, you must use the tool.

Download the installer from the Rockwell Automation Product Compatibility and Download Center (PCDC). Run the executable as an Administrator. Select version 20.12 from the available versions list. Follow the prompts and restart your computer when finished. Step 2: Prepare the Controller Flash after flashing

Rockwell Automation transitioned from RSLogix 5000 to Studio 5000 after version 20. Therefore, version 20 is the bridge between legacy and modern control platforms.

: Firmware 20.12 includes features and functions specifically designed to support safety applications, such as integrated safety controllers and safety communication protocols. This allows for the implementation of safety control strategies that are fully integrated with the control system.
