Mastering RSLogix 500: Understanding Version 8.10.00 (CPR 9) and Master Disk Licensing
The Master Disk (usually a 3.5" floppy disk, later a specialized CD/USB) contained the "activation key." To license the software on a PC, you had to "move" the activation from the disk to the hard drive.
3.5-inch floppy disks demagnetise and degrade over time, leading to bad sectors and lost activations.
This version is fully compatible with RSLinx for communication with PLCs over Ethernet, Serial (DF1), or Data Highway Plus (DH+).
Upon launching RSLogix 500 (specifically older versions like Rev 4, 5, or 6) or attempting to go online with an SLC processor, the software halts with . The dialog box typically prompts the user to insert a "CPR9 Master Disk" or simply a "Master Disk" to authorize the software.
Rockwell Automation’s RSLogix 500 remains a cornerstone software package for industrial automation professionals worldwide. Even with the rise of modern platforms like Studio 5000, thousands of manufacturing plants, water treatment facilities, and processing lines still rely heavily on legacy Allen-Bradley controllers. Specifically, the MicroLogix and SLC 500 families continue to run critical infrastructure.
