Install v35 side-by-side with v32 or v33 using Rockwell’s version manager. Do not uninstall older versions if you have legacy machines.
4/5 – A solid, professional release with meaningful improvements, but the forced L7 obsolescence and memory overhead mean it’s not a universal drop-in upgrade.
| Your Situation | Verdict | |----------------|---------| | | ✅ Yes. Use v35 for future-proofing and better instructions. | | Maintaining existing L7-based plant | ❌ No. Stay on v32 or v33 for those lines. | | Process plant needing totalization/PIDE | ✅ Yes. TOT and improved PIDE are valuable. | | Heavy compliance/security requirements | ✅ Yes. Controller-based security is now mature. | | Small standalone machine with L306/330ERM | ⚠️ Maybe – test memory usage first. |
