However, if you have ever searched for an "RSLogix 500 license," you know the journey can be confusing. Rockwell Automation has revised its licensing models multiple times, shifted to subscription‑based options, and introduced newer software like Studio 5000. This guide cuts through the noise.

Before diving into the mechanics of licensing, it is crucial to understand what a license for RSLogix 500 actually covers. RSLogix 500 is not a monolithic piece of software; it is sold in various "editions," each corresponding to the hardware you intend to program.
The oldest licenses used a red parallel‑port or USB hardware dongle (often called a "Crimson" or "master disk" dongle). Without the physical dongle, the software would not launch. These are no longer sold or supported but can sometimes be found on the secondary market (which we advise against—see legal notes below).
Since Rockwell has discontinued new perpetual licenses, your purchasing paths are limited but clear.

RSLogix 500 is the Integrated Development Environment (IDE) used to program, configure, and troubleshoot the following Rockwell Automation PLCs:
You cannot open an SLC 500 program in Studio 5000. If your plant has a mix of old SLC and new ControlLogix systems, you must maintain both licenses.
