Downloading version 3.9 from third-party "warez" sites or unverified public forums is strongly discouraged. Industrial control software that has been tampered with can pose severe security risks to Operational Technology (OT) networks. It is highly recommended to download the software only from the official (requiring a login) or to request a copy from the OEM if you hold a valid support contract.

The 3500 Rack Configuration Software v3.9 is a critical tool for maintaining legacy Bently Nevada / Allen-Bradley asset monitoring systems. While functional, users must manage the software lifecycle carefully, ensuring that downloads are sourced securely and that the operating system environment supports the legacy application to prevent downtime in critical monitoring operations.

However, if you are maintaining a legacy system where the configuration files were originally built in v3.9, it is often best to continue using that version to ensure backward compatibility with existing .rak or .dh configuration files.

For version 3.9 specifically, it is often found under the file name or cconfig.exe . 3500 System - Instrumart

A few important points:

Rockwell Automation software is proprietary and requires a valid software license key (often a physical dongle or a software activation file) to run in "Configuration Mode." While demo versions may be available for educational purposes, full functionality requires purchasing a license from Rockwell Automation or an authorized distributor.

Version 3.9 represents a legacy iteration of this software package. It allows users to define "Rack Configurations," which determine how the hardware modules within the 3500 rack operate, process sensor data, and trigger alarms.
