Differences Between the Original WebX client and ViewX
ATTENTION: This topic relates to the deprecated Original WebX client that is supported by this and previous versions of Geo SCADA Expert. For information about the Virtual ViewX client that is supported by Geo SCADA Expert 2019 onwards, for which the web server is hosted using IIS, click here.
Many of the functions and displays that are available from a ViewX client are also available from a WebX client—see the other sections of this guide for more detail:
- ViewX Client
- Object Menu
- Alarms
- Events
- Mimics
- Lists
- Trends
- Reports
- Status Displays
- Operator Document Stores.
The differences in how you use a WebX client compared with ViewX mostly relate to how you access items and functions.
The main differences between a WebX client and ViewX are:
- A WebX client provides operator, rather than configuration, access to the system. (Engineers have to use a ViewX client to make any configuration changes.)
- A WebX client can only display one window at a time (it cannot display inset windows as pop-ups as in ViewX). Any inset windows are displayed using the entire main display area and you use the Back navigation button to return to the previous screen.
- A WebX client can only connect to one server at a time.
On Geo SCADA Expert systems that have:
- Multiple Databases (see Multiple Databases in the Geo SCADA Expert Guide to Client Administration).
and:
- Contain Mimics that include hyperlinks to displays on other Geo SCADA Expert databases
WebX can navigate between the servers that run those databases and therefore display the other display(s) successfully. However, WebX cannot access multiple servers simultaneously. As such, in order for all of the ‘live’ data on a Mimic to update correctly in WebX, all of that data has to be sourced from the same Geo SCADA Expert database as that on which the Mimic itself is located. This includes embedded Mimics. WebX can only view 'live' data on embedded Mimics if those embedded Mimics, and the data shown on them, are sourced from the same Geo SCADA Expert database as the Mimic on which they are embedded.
Cross-database hyperlink support is possible providing that:
- The WebX client can obtain a network connection to each server (connecting to one server at a time)
and:
- The relevant Cross-Database Hyperlinks settings have been configured on each of those servers (see Define the Cross-Database Hyperlinks Settings in the Geo SCADA Expert Guide to Server Administration).
- Alarms are displayed using a dedicated screen on a WebX client.
- Audible alarms are not supported on a WebX client.
- Events are displayed using a dedicated screen on a WebX client.
- Lists are displayed using a dedicated screen on a WebX client.
- A WebX client can display the latest generated version of a report, providing that specific criteria are met. This includes the report being made available for display in WebX. For more information, see View the Most Recently Generated Version of a Report on a WebX Client in this guide, and see the Geo SCADA Expert Guide to the Crystal Reports Driver.
- A WebX client does not have the ViewX ribbon. For displays such as Trends and Mimics the WebX client provides access to options such as Zoom and Pan via a context-sensitive menu. Access the menu by right-clicking on the main display area.
- A WebX client cannot display the Explorer Bars. Equivalent Database Bar functionality is provided via the Database button. Equivalent Queries Bar functionality is provided via the Lists button.
- A WebX client can only display single windows that have been saved as Favorites. (Any Favorites that comprise multiple windows, or multiple windows and inset windows, are excluded from the Favorites list in WebX.)
- You cannot access the Geo SCADA Expert context-sensitive help feature from a WebX client. In the ViewX client, the context-sensitive help feature allows you to display help for the Geo SCADA Expert display that you are currently using. See Context Sensitive Help.
To display context-sensitive help in the ViewX client (and in many other Windows® applications) you press the F1 key. If you press F1 in the WebX client, then context-sensitive help for Microsoft Internet Explorer appears, rather than context-sensitive help for the Geo SCADA Expert application.
However, you can display the Geo SCADA Expert online help system by selecting the Help button on the WebX navigation bar. See Geo SCADA Expert Help. and See Understand the WebX Interface.
