Transparent message transmission
This function offers a transparent service to an FL-net higher layer.
This service notifies an FL-net higher layer of a received message. Upon receipt of such
a notification, the FL-net higher layer sends the same notification to the user interface
level. When the notification is sent to the user interface level, it is necessary to create
and return an associated response. For use instructions, see "5.3 Using the FL.NET
Module."
