Thewindow displays in the location on the HMI display as determined by the X and Y position in the Window Settings boxfor that window.Using the PLCThree objects are used by the PLC to call or display a base window. The PLC Control Object is used by the PLC todisplay full screen windows. The Direct and Indirect Window Objects are used by the PLC to display popup windows.The PLC Control ObjectThe PLC can display a full screen window by using the PLC Control Object. This object allows the HMI to continuouslyscan 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 thenumber of the requested screen to the next consecutive register. For example, if you assign internal data registerLW10 to a PLC Control Object/Change Window and the number 3 is placed into this register, then the HMI will displayScreen #3. Finally, it will put the number 3 into LW11. This allows the PLC to confirm that the Screen has beenproperly displayed by the HMI.You can create as many PLC Control Objects as you need -- each object is universal and is not dependent upon whichHMI screen is currently on display.To call a full screen window using the PLC Control object:1. From the Objects menu, select PLC Control. The PLC Control Object dialog box appears.0600-0069-0000 Rev. B
