Rockwell Automation no longer supports RSLogix 5000 versions 10 through 20. You cannot get technical support from Rockwell for these versions. However, the industrial base is so large that forums, integrators, and internal knowledge keep them alive.
Also, FactoryTalk Activation for v20 and older requires a legacy activation server. Newer Rockwell software may not coexist well with v20 on the same PC. Use a dedicated virtual machine for each major version.
Verdict: Best for stability and legacy maintenance.
Why is v20 so beloved? It is the peak of the classic architecture. It supports the L6x and L7x processors. It has no "fisheye" UI bugs. It compiles logic instantly.
Pick Version 19 or 20. Why? Emulate v20 is free-ish and easy to crack (ethically, use the Rockwell VM trial). V32 Emulate requires a paid license and a beast of a computer.
Best Choice: Version 32 (Studio 5000)
Best Choice: Version 20.05 (RSLogix 5000)
To understand the improvements, one must look at the three distinct eras of the software:
Best Choice: Version 35 or 36 (Studio 5000)
“Newer is not always better, but V32–V35 is genuinely better than V20 for any new build – faster, fewer crashes, and built-in tools that save hours per project.”
If you need cross-version coexistence, install V20.06 + V32 (or V35) side-by-side – they coexist perfectly on Windows 10/11. rslogix 5000 version better
The question of which RSLogix 5000 Studio 5000 Logix Designer)
version is "better" depends entirely on your specific controller hardware, stability requirements, and needed features. Because the software version must match the controller firmware
, there is no single "best" version for every scenario; instead, industry consensus points to specific versions for different goals. The Gold Standard for Stability: Version 20.04 For legacy systems and older hardware, Version 20.04
is widely considered the most stable "rock solid" release in the software's history. Legacy Peak : It was the final version before the rebranding to Studio 5000 Reliability : Expert users on
frequently cite it as a "go-to" for its lack of major bugs compared to early Studio 5000 Constraint Rockwell Automation no longer supports RSLogix 5000 versions
: It does not support modern hardware like the 5580 series ControlLogix or newer CompactLogix controllers. The Modern Choice for Features: Version 33 & 36
If you are working with modern, high-performance controllers, newer versions offer significant functional upgrades. Version 33
: Noted for being significantly more stable than its predecessor, Version 32, which suffered from occasional "program dump" bugs during hardware changes. Version 36 : The current cutting-edge choice, introducing native
client and server functionality within L8x controllers. This allows direct communication with third-party SCADA systems without extra middleware. Comparison: RSLogix 5000 vs. Studio 5000 RsLogix 5000 vs Studio 5000. When to Use Which One.
