Web Applications
TIP: Open Web Applications from the http://srv1.MyCompany.com/Web
RECOMMENDATION: To reduce the risk of cybersecurity attacks, access Web Applications only from client computers and not from the PME server.
Overview
Web Applications is the main interface for accessing PME 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 several configuration settings and tools to configure and customize your PME 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. |
Dashboards | View high level, historical and real-time data in dashboards and gadgets. |
Diagrams | View low level, historical and real-time data in one-line and graphics diagrams. |
Reports | Run reports on demand or scheduled. |
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 Default User Access Level Privileges and Customizing Access Level Privileges for details.
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.
/#Dashboards | /#Alarms |
/#Diagrams | /#Reports |
/#Trends |
For example, http://srv1.MyCompany.com/Web/#Trends
opens the Trends application in the browser.
Opening Web Applications Without Banner
You can open any of the Web applications by itself without showing the Web Applications banner and navigation bar. To open a Web application in this way, enter the PME server URL with /<application name>
in a browser address bar. 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 Alarms. It is displayed in the banner area of the Web Applications and is visible from any of the PME Web apps. 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.
When you select on one of the priority colored areas in the Annunciator, from anywhere in Web Applications, it opens the Alarm Viewer and automatically filters the view to show all alarms with that priority. You can customize the behavior of the Annunciator, including the alarm sound, on the Web Applications settings page.
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. select the speaker icon to mute or unmute the alarm sound.
NOTE: 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, select 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 PME system there are 3 reference points for time zones: the monitoring devices/sources, the PME server, the Web client (browser).
PME supports configurations where the devices/sources, the server, and the client are in different time zones. For example, a user in time zone A accesses the PME server which is in time zone B. The monitoring devices that are providing the data are located in time zone C.
The following table shows how the different Web Applications display time with regards to time zone:
Web Application | Time Zone Used for Display |
---|---|
Dashboards | Device/source time zone as configured in Management Console or Device Manager. |
Diagrams | Device/source time zone as configured in Management Console or Device Manager. |
Trends | Device/source time zone or Web client (browser) time zone. Device/source time zone as configured in Management Console or Device Manager. Web client (browser) time zone as configured in Trends application. |
Alarms | Device/source time zone as configured in Management Console or Device Manager. * |
Reports | Time zone can be manually selected. Default is Web client (browser) time zone. |
* Alarms has tooltips that show the time in both the device/source time zone, and the Web client (browser) time zone.
NOTE: Web Applications uses Management Console or Device Manager time zone settings for the device / source time zone. The time zone settings in Management Console or Device Manager are set per device and must be configured correctly, for Web Applications to show the correct time. The time zone settings in Management Console or Device Manager are independent of time zone settings on the devices themselves. Web Applications does not use the time zone settings on the devices themselves.
Disabling the time zone option Adjust for daylight saving time automatically in the Windows Date & Time settings on the PME application server affects the PME Windows applications, not the web clients. To disable daylight savings time for all the PME applications, perform the following:
-
On the PME application server, in the Windows Date & Time settings select an alternate time zone without Adjust for daylight saving time automatically option.
For example: If your existing Windows time zone is (UTC-08:00) Pacific Time (US & Canada), which has the Adjust for daylight saving time automatically option then select (UTC-8:00) Coordinated Universal Time-08, which does not have the Adjust for daylight saving time automatically option.
- On the Management Console for existing devices, set the Time Zone as the selected Windows time zone.
NOTE: For new devices, the Management Console Time Zone is set to the Windows time zone automatically.
