5.5.4 Safe and non-safe elements in the hardware configuration
Safe and non-safe elements are shown in the hardware configuration using different
colors:
 Safe elements are marked yellow.
 Non-safe elements are marked gray.
The majority of elements are only marked as safe or non-safe when they are dragged
to a corresponding input or output:
 Safe elements that are dragged to a safe input or output are marked yellow.
 If an element marked gray is dragged to a safe input or output, it remains marked
gray but can be marked yellow by editing.
How to mark an element as a safety element:
 Double-click a gray or red marked element or click it using the right mouse button
and select Edit... on the context menu. The Element settings window opens.
 Activate the Safety element checkbox.
 Click on OK to close the Element settings window. The element is now marked
yellow.
5.5.5 Expanding elements
Some elements consist of a group of two or more sub-elements, such as an interlock
that consists of a safety switch as input element and an interlock with locking as output
element. Normally these elements must be connected to one module (e.g. WS0-XTIO),
but some of these elements can be expanded so that the individual sub-elements can
be connected to different modules.
How to expand an element:
 Place the element (e.g. an interlock) in the Parking area.
 Right click the element to open the context menu.
 Select the Expand command. The element in the Parking area is replaced by its
sub-elements which can be treated like individual elements.
