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.
The Fast Scan Immediately option of the Fast Scan Widget does not work with a Mobile Internet Thin Client (MIC)
The VTScada Anywhere Client adds the following features. Operators may:
- View and use all pages, subject to each operator's security privileges.
- Perform limited configuration operations to a standard application, including:
- Copy existing tags

- Delete a tag
- Add new tags
- Modify Alarm Notification System options and pronunciation.

Only one instance of a script application may run at a time - if it is running on a workstation, it may not also run on an Internet connection. - Managers may work with security accounts.
- Administrators may configure security.
- Run and download reports, generated as text files. (See following note.)
- Create and download ChangeSets.
- Export and download data from the HDV.
- Unique to the Anywhere client: sign in using OpenID Connect Authentication.
- Run the VAM as an application with the following exceptions:
- Cannot use Get From ChangeSet
- Cannot use Clone From ChangeSet

Edge and Chrome block PDFs shown in the Web Browser widget when using the Anywhere Client. This is related to the sandbox attribute set on the iframe.
If generating a file using the VTScada Anywhere Client, it will be transferred to your browser automatically. Check your browser's download history. (Will vary by browser.)
Only text files can be generated by a thin client, not spreadsheet or database files.
Similarly, Excel templates cannot be used when reporting via a thin client.
This applies to report generation, HDV exports, note exports, ChangeSet creation, and tag exports.
You cannot view a generated file (such as a report) within the Anywhere Client. The client shows only the VTScada user interface.
