You can create a hierarchical structure for the screen changes.
Using a [Hierarchical Screen Change] switch, you can move up or down a level in the screen hierarchy.
Using a Previous Screen switch moves you up a level in the screen hierarchy. Using a Screen Change switch moves you through screens on the same level.
If the [Hierarchical Screen Change] check box is cleared, screen changes will be on the same hierarchical level.
A maximum of 32 levels can be set.
You cannot force a Hierarchical Screen Change from the device/PLC. You can only change screens within the same hierarchy level.
