12.8.2 Restrictions for Displaying Windows

• You can draw multiple window parts on the base screen, but the maximum number of local windows you can display simultaneously on a single screen is as follows. When global windows are set up, the number of local windows you can display simultaneously on a screen decreases by 1.
  For details, refer to 12.9 Displaying Multiple Windows on a Single Screen.

• When you enable the [Continuous Read] setting in a Window part, even if the window is not visible it is counted as one of the displayed windows.
  As a result, the number of windows the system can display is equal to the maximum number of windows that can be displayed minus the number of window parts with [Continuous Read] enabled.

• Only one Global Window is allowed in each project.

• When the Window Number is not set, the Window cannot be displayed.

• When a Window has been positioned to stick out past its Base screen, the Window is adjusted to fit inside the Base screen.

• When using the GP3000 Series, LT3000 Series, or ST3000 Series, set both the X-coordinate of the window position and the width of the window in 4-pixel increments. If not set properly to 4-pixel increments, the values will be automatically adjusted to 4-pixel increments.
  

• If multiple devices/PLCs are connected, only the device/PLC specified in the GP System Data Area can display Global Windows.

• A Global Window cannot be displayed when the device monitor is on.

• When using the Window Display Switch (Special Switch) to display a window, if there are multiple window parts with the same [Window Number] on the same screen, the first registered window will display. All other registered windows do not function.

• Parts on screens that are completely hidden by an active Window cannot be activated by touch. However, if only a portion of a part is hidden by a Window, the viewable portion can be activated by touching it.

• The maximum number of window parts with [Continuous Read] enabled that you can draw on one screen is the maximum number of windows that can be displayed. When this number is reached, you cannot use any other windows.

• Up to 4 (up to 3 when using Global Window)
  SP5000 Series
  GP4000 Series (excluding GP-410*)
  LT4000 Series
  IPC Series
  ST6000 Series
  STM6000 Series
  STC6000 Series
  ET6000 Series
  

• Up to 3 (up to 2 when using the Global Window)
  Models other than those above

• When using [Continuous Read], any scripts set on a Window will run if the script condition is satisfied, even if the Window is not displayed.
  If you do want to run the script, confirm the [Continuous Read] check box is cleared.

• When using the [Disable touch outside windows] option, touch is enabled only on the window displayed on top. When a window set up with the [Disable touch outside windows] option is displayed, and another window is opened without the [Disable touch outside windows] option, touch is enabled only on the newly opened window.
  

• For information on [Disable touch outside windows] in combination with other interlock features, please see the following.
