Many industrial plants run on Windows 7 or Windows Server 2012 R2. Newer CM2 SCR versions (v9+ and cloud-native) require Windows 10/11, .NET 6.0+, or SQL Server 2019.

In a typical late-90s embedded system, CM2 would be a memory-mapped peripheral or a co-processor managing system configuration at reset. The SCR inside CM2 was a volatile 8‑ or 16‑bit register with bits controlling: Newer CM2 SCR versions (v9+ and cloud-native) require
