HMI User Privilege Management: Role-Based Access Control & Auto-Logout Security

Prevent unauthorized machine parameter tampering: configuring multi-tier user groups (Operator, Maintenance, Supervisor, Engineer), RFID badge logins, and idle auto-logout timers.

  • Critical machine parameters (PID gains, safety bypasses, stroke limits) must be locked behind Engineer/Supervisor privileges.
  • RFID badge readers allow operators to log in instantly without typing greasy fingerprints onto virtual on-screen keyboards.
  • Automatic logout timers (typically 5 to 10 minutes of screen inactivity) prevent operators from leaving supervisory rights unattended.
