• Write a value (byte) to a PLC or system variable when you release
the button

5.10.3 Representation of Buttons
Attributes for displaying a button are:
– Foreground and background color for the pressed and released
states
– Position and dimension of the button
– Frame for the pressed and released states
Note:
• When you program an input variable in the same way as for a key-
board-operated operating device, a button is automatically generat-
ed around the variable.
• Buttons can only overlap with background images.
• Buttons in tables that contain a variable have no frame and have one
line.
• Buttons in input and output masks are not allowed to contain any in-
put variables.
• When you program a button with an input variable of the type Selec-
tion Text or Selection Image, the Enter button is automatically cre-
ated (on request). In other words, no input or output mask is linked
for both of these types. The user presses the button to navigate in
the corresponding list. If the selection text variable only has one line,
the variable value is decremented when you press the left half of the
button, and incremented when you select the right half. For multi-line
selection text variables and for selection image variables in general,
the variable value is decremented when you press the top half of the
button, and incremented when you press the bottom half.
The following image depicts a button that has a horizontal layout.
This type is activated for selection text that only has one line.
