Calling a popup window
If a function key object is created to call a popup window, the window that is displayed is generally overlaid over all
other windows that are on display. Think of calling a popup window as opening another active window for display.
 To call a popup window using a function key object:
1. From the Objects menu, select Function Key. The New Function Key Object dialog box appears.
2. In the General Tab, check the Display popup window option button. Note that the Close this popup window
when parent window is closed checkbox will cause the popup to close automatically whenever the base
window changes.
3. In the same section, enter the Window No. you want to call.
4. Select the Shape tab, click the Use shape or Use picture checkbox, and then click the Shape Library button
or Picture Library button. Select the shape or bitmap you wish to use to represent the function key and click
OK.
5. Select the Label tab and check Use label and create a label for the function key.
6. Click OK to return to the main screen of EasyBuilder.
7. Place the function key object where you want it on the window you are editing. You must select a window
that is less than full size when using the Popup Window function.
To display a full screen or popup window, press the touchscreen where the function key object is located. The
window displays in the location on the HMI display as determined by the X and Y position in the Window Settings box
for that window.
Using the PLC
Three objects are used by the PLC to call or display a base window. The PLC Control Object is used by the PLC to
display full screen windows. The Direct and Indirect Window Objects are used by the PLC to display popup windows.
The PLC Control Object
The PLC can display a full screen window by using the PLC Control Object. This object allows the HMI to continuously
scan a PLC register to display a full screen window, which corresponds to the number in the PLC register.
Once the HMI displays a full screen that is requested by the PLC Control Object, the HMI will automatically write the
number of the requested screen to the next consecutive register. For example, if you assign internal data register
LW10 to a PLC Control Object/Change Window and the number 3 is placed into this register, then the HMI will display
Screen #3. Finally, it will put the number 3 into LW11. This allows the PLC to confirm that the Screen has been
properly displayed by the HMI.
You can create as many PLC Control Objects as you need -- each object is universal and is not dependent upon which
HMI screen is currently on display.
