The values of the inputs are stored in the data interface (DB46).
The PLC program evaluates the current inputs and updates the data in the interface for output.
The C7 OP reads all the values independently from the interface and updates its display.

Link the screens and enable navigation via softkeys

To enable the second screen to be called up on the C7, you must use ProTool/Lite to configure the
screen change from start screen Start_QM to plant screen Plant_QM and back. Navigation from the
first screen entry to the second and back must also be configured for the plant screen.
To do this, assign a softkey to the Select Screen function in both of the screens. You will use these
softkeys to activate the screen change. In the plant screen, assign the Jump within Screen function in
both screen entries.
Open the screen Start_QM and select the Softkey F5 . The dialog boxes Softkey-F5 and Select
Object appear.
In the dialog box Select Objekt choose the function Select Screen from the Screens. A short
description of the function is displayed.
