Improved cross-referencing and data table monitoring compared to older v5 or v6 releases. Understanding the "Master Disk" Activation
RSLogix 500 version 8.10.00 CPR 9 represents a mature, stable release of the standard programming software for the Allen-Bradley MicroLogix and SLC 500 controller families. As part of the CPR 9 release cycle, this version focused heavily on stability enhancements, security updates, and compatibility with modern Windows operating systems of the time (specifically Windows 7 and Windows 10). The "w/ Master Disk" designation indicates the inclusion of the required activation dongle or master license diskette necessary to authorize the software on legacy industrial workstations.

The master disk is a physical 3.5-inch floppy disk containing a hidden activation file ( EVRSI.SYS ) required to run the software. Modern Shift : Modern Rockwell software has moved
: Early versions of RSLogix required a physical floppy disk or CD (the master disk) to move "activation keys" onto a hard drive. Modern Shift : Modern Rockwell software has moved to FactoryTalk Activation
To illustrate the value, consider a real scenario:
