Flashing firmware is a delicate operation. A failure can brick the controller. Follow this protocol precisely.
First, let's clarify the terminology. In Rockwell Automation’s world, "firmware" refers to the embedded operating system that runs on the controller hardware (ControlLogix, CompactLogix, DriveLogix, and SoftLogix). is the specific revision of that operating system.
RSLogix 5000 v20.12: The "Ghost" Version and What You Need to Know rslogix 5000 firmware 20.12
Turn the physical keyswitch to mode. Avoid using Wi-Fi; use a direct USB or Ethernet connection. Firmware Mismatch Error when downloading project.
While upgrading to firmware 20.12 offers several advantages, there are also considerations to keep in mind: Flashing firmware is a delicate operation
Ensure you have RSLogix 5000 version 20.01 or later installed to communicate with the 20.12 controller.
In a ControlLogix Redundancy chassis, the secondary controller stays in "Syncing" or "Disqualified" after flashing to 20.12. Solution: Redundancy modules (1756-RM2) also require specific firmware that matches the Logix firmware. Ensure your RM2 firmware is at least Revision 12. Also, remember that the secondary controller must be flashed before inserting it into the redundant pair. First, let's clarify the terminology
For users still working with RSLogix 5000 v20, it's important to recognize that this version operates on a different paradigm than both its predecessors and successors. The special behavior of v20.03, which locks projects to that specific minor revision, was a unique departure from the standard compatibility model and served as a transitional approach toward the more integrated Studio 5000 environment.
