Hardware requirements are modest by today's standards: a multi-core processor, 2 GB of RAM, and about 2.5 GB of free hard drive space are more than sufficient.
: This refers to the physical 3.5-inch floppy disk (the "Master Disk") used to move the EVRSI activation key
In the early 2000s and 2010s, Rockwell software was often delivered on 3.5-inch floppy disks or CDs. The refers to the original, factory-pressed installation media that contains the core executable and, crucially, the evmove or master disk activation system. Unlike modern subscription licenses, a master disk allowed you to install the software without an internet connection, using a physical disk as a dongle or key-disk.
| Term | Meaning | Significance | | :--- | :--- | :--- | | | The software itself. The programming environment for SLC 500 and MicroLogix PLCs. | The core tool for creating, editing, and troubleshooting programs for these controllers. | | 8.10.00 | The software's specific version number. | This is a "point release" that provides a snapshot of the software's features and hardware support at a given time. | | CPR 9 | Stands for "Coordinated Product Release 9". | A major Rockwell initiative to synchronize the release of its entire software suite (including RSLogix, FactoryTalk, RSLinx) for seamless interoperability. | | "w Master Disk Verified" | A licensing and activation phrase. | Indicates the software uses a physical "Master Disk" (typically a 3.5-inch floppy) containing a critical activation file. "Verified" likely means the disk is original and functional, not a copy. | rslogix 500 81000 cpr9 w master disk verified
Even when a disk is verified, industrial automation engineers frequently encounter hurdles due to modern operating system restrictions. Windows 10/11 Compatibility Issues
Directly programs SLC 505, SLC 5/04, SLC 5/03, and all legacy MicroLogix units (1000, 1100, 1200, 1400, 1500). The Role of the Master Disk
If you are currently troubleshooting an activation issue or trying to get this specific software version running, tell me: Hardware requirements are modest by today's standards: a
Modern 64-bit systems do not support 16-bit legacy activation drivers. Running this software on modern IT infrastructure requires a 32-bit Virtual Machine (VM) running Windows XP or Windows 7 32-bit. Communications Layer
The key is written to a hidden, system-protected directory on the target drive (usually C:\ or C:\Reset ).
This number is frequently misunderstood. It is a version number in the traditional semantic sense (like 8.10.00). Instead, in Rockwell’s legacy catalog and part numbering system, "81000" often points to a specific distribution kit or product code . Historically, this correlates to RSLogix 500 Standard Edition or a specific licensed toolkit. For many automation engineers, "81000" is shorthand for the professional package that includes all necessary drivers and utilities, distinguishing it from "9324-RL0300ENE" (Starter Edition) or "9355-WABOENE" (Professional Edition). Unlike modern subscription licenses, a master disk allowed
Using a "verified" master disk version ensures you are using a legitimate license, which is crucial for:
Tighter integration with FactoryTalk Security for multi-user environments. The "Master Disk Verified" Requirement
Open File Explorer, navigate to Folder Options, and check .
Many manufacturing plants run air-gapped industrial PCs (IPC) that still use Windows XP Embedded or Windows 7 32-bit. CPR9 is lightweight (less than 500MB installed) and does not require the heavy .NET frameworks or SQL instances demanded by modern FactoryTalk Suite. It boots quickly and responds instantly—critical when a line is down.
