Set up global connections - Display tab
To set up global Display connections
- In the Explorer window, double-click the Global Connections icon to open the editor.
- In the Global Connections editor, click the Display tab.
- If a maximum update rate has not been selected, in the Maximum update rate (seconds) box, select the maximum rate at which the data source will supply data to the global connections.
- The first two connections are write connections for sending values from the application to the data source. Assign a tag to these connections:
- Replace Display Number
- Display Print Active
- The second two connections are read connections for sending values from the data source to the application. Assign a tag or expression to these connections:
- Remote Display Number
- Remote Display Print
- The next two connections are read connections for closing On Top displays. Assign a tag or an expression to these connections:
- Close an On Top Display
- Close All On Top Displays
- The parameter connections are optional read connections to be used for displays that use parameters when they open. Assign a tag or expression to these connections:
- Parameter file
- Use Parameter List
- Parameter Tag #1 to 10
Tip: |
To unassign a control, select the control in the Tag or Expression column and do one of the following:
- Press Backspace on your keyboard repeatedly to remove the assignment one character at a time.
- Double-click twice to highlight the text, and then press Delete or Backspace to remove the entire assignment at once.
Do not assign an expression consisting of a constant to the Remote Display Number. If you do, the display whose number matches the constant opens and can never be closed or changed.
If a remote display print is in progress, the application ignores subsequent print requests from the data source until the display print has been processed.
