Note: Windows 7 and Windows Server 2016 are not supported in V35.
Some complex AOIs created in V32 using embedded structured text may require re-validation. Rockwell has tightened the compiler to prevent ambiguous pointer references. Test all critical AOIs in a simulated environment before deploying to production.
| Issue | Likely Fix |
|-------|-------------|
| V35 won’t install | Uninstall older FT Services; run as admin; disable antivirus |
| Online edit fails | Check controller firmware = 35.011+; download if needed |
| Serial ASCII not working | Confirm controller firmware >=35.011; port mode = ASCII |
| Git integration grayed out | Install Git for Windows (2.30+) first |
| Safety signature mismatch | Go to Safety → Unsign → then resign after edits |
Upgrade if:
Stay on Version 33/34 if:
Final verdict: Studio 5000 Version 35 is a forward-looking release that modernizes the Rockwell ecosystem for the cloud, security, and agile development. While it introduces a learning curve around Optix and CIP security, the long-term productivity gains are substantial.
