Studio 5000 Version 35 -
The release of Studio 5000 Version 35 by Rockwell Automation marks a significant step forward in industrial automation, focusing heavily on simulation, process efficiency, and expanded hardware support.
Originally released in late 2022, Version 35 introduces several powerful features that streamline the bridge between virtual design and physical commissioning. Top 5 Features of Studio 5000 V35 Studio 5000 – V35: What's New - The Automation Blog studio 5000 version 35

For Cybersecurity Teams
Upgrade to V35 immediately if your plant is exposed to corporate IT networks or remote access. The CIP security features (especially device-level ACLs) are non-negotiable for meeting IEC 62443-3-3 requirements. The Improvement: The new PLS instruction allows you
1. Programmable Limit Switch (PLS) Instructions
This is the standout feature of v35. Previously, implementing PLS functionality required creating complex arrays and ladder logic to track position and turn outputs on/off based on cam profiles.
- The Improvement: The new PLS instruction allows you to configure output switching based on a position input (encoder or resolver) directly within the instruction.
- The Benefit: It drastically reduces the code complexity for rotary tables, cam boxes, and packaging machines. It supports up to 64 discrete outputs and allows for on-the-fly switching adjustments via the HMI. If you build rotary machinery, v35 is worth the upgrade for this alone.
Known Issues and Limitations (Honest Assessment)
No software is perfect. Users on Rockwell’s Knowledgebase (Answer ID: QA55632) and Reddit/PLCr have reported:
- Slow first-time opening of large L5X files (over 100 MB) – up to 5 minutes.
- Optix tag sync errors when using UDT arrays with custom properties.
- Version 35 simulation (Emulate 35) does not support all 5069 Compact I/O modules. Use real hardware for testing advanced analog modules.
