FUNCTION_BLOCK IMG_BOOL
| An
instance of this function block type provides a human/machine
interface (HMI) element for the entry of an IEC 61131-3 BOOL
element in a similar fashion as the IN_BOOL
function block type, with the additional feature that the user can use
the IMG0 and IMG1 inputs to specify the icons to be
displayed when the Boolean output stands at FALSE or TRUE,
respectively.
See the PNP_MVCL
configuration for an example of the use of an instance of this type.

FBDK. A "starter" collection of images is also provided in the
following locations of the
