Capabilities of Internet Thin Clients

Tools and features vary by choice of thin client. Capabilities of each client are listed here, starting with the most restrictive connection option:

The Mobile Internet Client (MIC) provides the following features:

  • For any application page, operators may choose between an minimal display optimized to reduce bandwidth, or a full display including all widgets and graphics.
  • Operators can view I/O tag values on a page by page basis.
  • Operators can set output tag values.
  • View and acknowledge current alarms.
  • View the alarm history.
  • View a trend graph (HDV display) for any I/O tag.
    Graphs are images, updated only when recreated using a refresh. Data cannot be exported
  • View a slippy map.
  • If the mobile device supports the "pinch" user interface, operators may scale the HDV display.
  • No access to the following system pages: Reports page, Operator Notes, the full HDV page, Thin Client Monitor.
  • No access to the VAM as an application.

The mobile client is intended for use with a personal mobile device. It does not include a "sign out" option. The sign-out will occur automatically several minutes after closing the application. If sharing a device, you should use one of the following clients for increased security.
