This version addresses a vulnerability that could allow attackers to cause a Denial of Service (DoS)
RSLogix 5000 firmware 20.12 (listed as 20.012 in the PCDC) is a maintenance release for ControlLogix and CompactLogix controllers that resolves specific hardware anomalies and ensures compatibility with version 20 software. The firmware supports various legacy hardware, including CompactLogix L3x/L2x and 1756-L6x controllers, and requires a two-step upgrade process for older revisions. For detailed release notes on specific hardware, visit Rockwell Automation Literature .
Early v20 versions (specifically v20.03 ) were notoriously incompatible with other v20 files. Firmware 20.12, when used with software v20.04 or v20.05 , restores the ability to open, upload, and go online with multiple minor revisions without forced conversions. rslogix 5000 firmware 20.12
: This version is widely used with 1756-L6x and early 1756-L7x ControlLogix controllers, as well as several 1769 CompactLogix models.

Firmware 20.12 supports a wide range of Logix controllers, including various ControlLogix and CompactLogix models. It notably added support for the GuardLogix 5572S and 5573S safety controllers, extending the performance of the ControlLogix 5570 family into safety applications. Furthermore, a strict rule exists: controllers with firmware v20 require RSLogix 5000 v20. For newer controllers (e.g., Series B CompactLogix 5370 L3), a minimum of firmware v20 is mandatory.
