An instance of this function block type extends the local multicast functionality of the LOADL function block type by adding a QI input. Local publication of the workpiece loading data and event upon an occurrence of a REQ event is enabled when the QI input is true and disabled when it is false.

The default value for the ID input (when no parameter value is explicitly connected) is the function block instance name.

See the TESTBED_MVL.MODEL.CHAIN_MDL device configuration for an example of the use of an instance of this function block type.
