Once the numeric input cursor point object has been selected, that is, has input focus, the user can activate the object by:
When the operator activates the numeric input cursor point, the numeric pop-up keypad or scratchpad opens. The operator types a numeric value in the pop-up and presses Enter. The value appears in the cursor point and is sent to the Value connection at the data source.
If a write expression is assigned, the application evaluates the expression and sends the expression value to the Value connection.
If the cursor point has input focus, you can press a Move Up Key button object or a cursor up key on an external keyboard or keypad to increase the Value connection by the ramp value, or press a Move Down Key button object or a cursor down key to decrease the Value connection by the ramp value.
If the Optional Expression is assigned (on the Connections tab), the numeric input cursor point will not support ramping.
The ramping behavior at run time also depends on whether you set up auto repeat. Move Up/Down keys have their own auto-repeat properties. Auto-repeat for cursor keys is controlled through the Keyboard settings in the Control Panel on the run-time PanelView Plus 7, PanelView Plus 6, PanelView Plus, or PanelView Plus CE terminal.
Tip: |
The cursor point object does not need to have input focus to call a pop-up. It does have to have input focus to perform the ramping function. Check the Key Navigation box (General tab) if you want the operator to be able to navigate to the cursor point with the keyboard and give it input focus. |
The numeric input cursor point shows the value of the Indicator connection at the data source. The application clears the display before showing a new value. If the Indicator connection is unassigned, the object displays the last value written out.
When an operator opens a display at run time, the application reads the values of all assigned controls and updates the display based on these values.
