to pop up its description (if any).
An instance of this Composite Function Block type encapsulates an
instance of the DO_PI FB type,
along with an instance of the SUBL_1
type, which facilitates the use of Raspberry
Pi GPIO inputs with the Local Multicast and
Tagged Data design
patterns.
-
If no value is given for the
IDinput parameter of an instance of this FB type, its instance name is taken as the ID of the associated Local Multicast channel.
See the GPIO_TEST5L
and GPIO_TEST6
System configurations for examples of the use of this FB type.
