The properties described in this topic apply both to User Forms and User Pattern Forms. (User Patterns only apply to systems on which Geo SCADA Expert can create new User accounts automatically as part of an External Authentication process. For more information, see Create User Accounts from a User Pattern.)
Geo SCADA Expert clients can regularly report location information to the Geo SCADA Expert server. This can be useful if you want to track users and determine their proximity to database items (such as outstations). Alarms can then be redirected appropriately. To use this functionality, set the location Source to Dynamic on the user's Location tab (see Use the Location Tab to Specify an Item's Geographic Coordinates in the Geo SCADA Expert Guide to Geographical Location Support):
The following types of client can report location information to the server:
- ViewX—A standard ViewX client.
-
- Mobile—The Geo SCADA Mobile App for the Android® and iOS® operating systems.
A client can report the following information to the server:
- WGS84 position co-ordinates (latitude and longitude in degrees)
- Altitude
- Position and altitude accuracy
- Date and time
- Heading
- Speed.
ViewX and Virtual ViewX clients update their location information to the server when the user logs in. Mobile clients update the server as a result of a change in location. All clients will update the server no more than once a minute. Geo SCADA Expert does not direct alarms to clients that are not logged in.
To specify which clients you want to update the server with location information:
-
Either:
- Display the relevant User Form (to define the settings that apply to an individual User account).
- Display the relevant User Pattern Form (if applicable to your system, to define the settings that Geo SCADA Expert is to apply to new User accounts that it might be triggered to create automatically at logon.)
- Select the General tab and scroll down to the User Location Sources check boxes.
- Define the User Location Sources settings for the user account.
- Select the check boxes for the clients that you want to update the server with location information.
- Clear the check boxes for the clients that you don't want to update the server with location information.
You select the Virtual ViewX check box in the User Location Sources section if you want to record the current geographic location of the Virtual ViewX client. As part of the Virtual ViewX logon process, the web browser prompts you to allow the Virtual ViewX web server to know the client's current location. If you allow this, the location is updated after you login to Virtual ViewX. You can view the location from the Position status attribute. This location is based on the browser's settings.
