The "Master Disk" Activation Advantage

Modern Rockwell licenses require FactoryTalk Activation Manager (FTAM) which must phone home or use a hosted license server. If your plant is air-gapped for security (e.g., defense or critical infrastructure), FTAM becomes a nightmare. The Master Disk activation is offline, permanent, and does not expire.
