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. Therefore, think of calling a popup window as opening another active window
for display. Note that the maximum number of popup windows displayed at any one time is six.

You must select a window that is less than full size when using the Popup Window function.

window displays in the location on the OIT display as determined by the X and Y position in the Window Settings
box for that window.

Using the PLC to dis play a base win dow
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 OIT to
continuously scan a PLC register to display a full screen window, which corresponds to the number in the PLC
register.
Once the OIT displays a full screen that is requested by the PLC Control Object, the OIT 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 OIT 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 OIT.
You can create as many PLC Control Objects as you need- each object is universal and is not dependent upon which
OIT screen is currently on display.
