Web Applications
Web Applications is the main interface for accessing Power Operation power system information. Use Web Applications to view real-time data, alarms, historical trends, key performance indicators, reports, and other information about the power system you are monitoring. Web Applications also provides a number of configuration settings and tools to configure and customize your Power Operation system.
The following is a list of applications for accessing power system information through Web Applications:
| Application | Function |
|---|---|
| Alarms | View and analyze Incidents, Alarms, and Events; Acknowledge alarms. |
| Diagrams | View low level, historical and real-time data in one-line and graphics diagrams. |
| Trends | View trends for real-time and historical data. |
For a list of configuration tools and settings, see Web Applications settings.
When you open Web Applications, you are prompted to log in with your username and password. The access level assigned to your username determines which applications and which functions are available to you. See Managing user accounts, role names, and mapping for details.
Opening Web Applications
Open Web Applications from Power Operation folder on your desktop, the Schneider Electric folder on the Start Screen, or by entering the Power Operation server URL into your browser Address bar. For example: https://srv1.MyCompany.com/WebHmi
RECOMMENDATION: To reduce the risk of cybersecurity attacks, access Web Applications only from client computers and not from the Power Operation server.
Specifying which application to open first
When you connect to Web Applications through a client computer, the application whose link is on the left of the series of application links opens in the browser. To specify a different application to open first, add one of the following application query parameters into the Web address.
| /#Diagrams | /#Alarms |
| /#Settings | /#Trends |
For example: http://srv1.MyCompany.com/WebHmi/#Alarms opens the Alarms application in the browser.
Opening Web Applications without a banner
You can open any of the Web Applications by itself without showing the Web Applications banner and navigation bar.
To open a Web Applications without a banner:
In the browser address bar, enter the PO server URL with /<application name>.
For example: http://srv1.MyCompany.com/Trends opens the Trends application in the browser without the Web Applications UI elements.
Web Applications User Interface
The top right of the banner contains:
- Your user name: The user name you used to log in.
- Logout link: Logs you out of Web Applications and returns you to the log in page.
- Help link: Opens the browser-based online help for the Web Applications component and the integrated applications.
Alarm Annunciator
The Alarm Annunciator shows information on the number of active and unacknowledged About Alarms. It is displayed in the banner area of the Web Applications and is visible from any of the Power Operation Web Applications. The Annunciator alerts you to any new alarms that are occurring in the system. You can configure it to play a sound when certain alarm conditions are met.
The Annunciator looks like this:
In this example, the Annunciator shows:
- 1 low priority, active and unacknowledged Alarm (blue)
- 8 medium priority, active and unacknowledged Alarms (yellow)
- 10 high priority, active and unacknowledged Alarms (red)
The presence of the speaker icon indicates that it is configured to play a sound when new active and unacknowledged alarms occur. Click the speaker icon to mute or unmute the alarm sound.
You must have controller, operator, or supervisor-level access to see the Annunciator. If you have observer or user-level access, it is not displayed.
Library Pane
The library pane contains items and configuration options for the selected application. To show or hide the library pane, click the bar on the right or left side of the display area.
Display Pane
The display pane loads the data visualization selected in the configuration pane.
Time Display in Web Applications
Most of the information displayed in the Web Applications is time based, such as timestamped real-time data and historical data. In a Power Operation system the server converts timestamps to the local server time zone.
Power Operation supports multi-site configurations where the devices/sources, the server, and the client are located in different time zones. For example, a user in time zone A accesses the Power Operation server which is located in time zone B.
