An instance of this function block type utilizes an instance of
the OUT_BOOL type to present a
colored circle with an associated label.
- When an event occurs at the REQ input, the circle
changes to the color specified by the FLASH input for a
period determined by the DT input, and then reverts to the
default FALSE-state color (white) for the OUT_BOOL
type.
- At the end of the period an event occurs at the CNF
output.
- The behavior of this component upon the occurrence of a sequence
of events at the REQ input is determined by the behavior of
the E_DELAY function block
instance.
