The CygNet Thin Web Client supports its own context menu visible in the web view.

Perform the following actions from the TWC context menu:

• Right-click on a control to view the context menu for a selected point. When the context menu is active the main part of the page is dimmed. The context menu is divided into four sections:
1. Acknowledge Alarm — If the point is in alarm, the Acknowledge Alarm icon will indicate this state. Click to acknowledge it and the Acknowledge Alarm will disappear.
2. Current Value — View read-only Current Value attributes for the selected point.
3. Alarm Summary — Click the toggle switch to view Alarm Summary values.

   From here you can edit alarm threshold values or the alarm priority in the context menu, which will be written back to the point on the CygNet host server. A warning will show if you do not have the appropriate security access level to edit points.

   1. Click (Edit) then click on the Value or Priority you want to edit.
   2. Enter a new value or use the spin control to increase or decrease the value.
   3. Click (Save) to write the new value back to the point configuration on the CygNet host server.
   4. Or click (Cancel) to abort and return to the read-only mode.
4. Chart — Click the toggle switch to view a quick Chart for a selected point. The series shows the last eight hours of value history and will update with each new point value received. Hover over any point in the series to reveal a small popup showing the UDC, point value, and timestamp. From here you can add the currently viewed point to a new or existing ad hoc chart which will display in a new browser tab. Note that an ad hoc chart is not a template. Any saved chart is hard-coded with specific point tags.
   1. Click Add to new chart to add the selected point to a new ad hoc chart. A new chart titled NewChart<n> will open in a new browser tab, where you can rename, duplicate, or delete the chart. You can also view the chart data in a grid and export data to an Excel file.
   2. Click Existing chart(s) to open a drop-down list of previously saved ad hoc charts.
   3. Click the + <chart name> to add the selected point to that chart. The selected chart will open in a new browser tab.  Note: If you add a point to an existing chart that is already opened in another tab, then the point is added to that open chart but TWC does not shift focus to that tab. You will remain on the current tab.
   4. Click Existing chart(s) again to close the drop-down list of existing charts.

   Once saved an ad hoc chart can be viewed from the main CygNet TWC web view via the (Saved Charts ) button. See Viewing Data in a TWC Ad Hoc Chart for more information about working with ad hoc charts.

• Click (Close) to close the context menu and return to the TWC page that launched the menu.
