When the control is on, the screen displays the selected
operating modes in the header: The machine operating mode
at left and the programming mode at right. The currently
active mode is displayed in the larger field of the header,

above the soft-key row indicate the number of soft-key rows

Setting screen layout

The screen layout is user-selectable. In the Programming mode,
for example, you can have the control show program blocks in the
left window while the right window displays programming graphics.
You could also display the program structure in the right window
instead, or display only program blocks in one large window. The
available screen windows depend on the selected operating mode.
Set up screen layout:
Press the screen layout key: The soft-key row
shows the available layout options
