This module processes all transmission tasks, initiated by the user program
(transmission impulse via START). Thereby a new transmission task is accepted
only then when no other task is active (BUSY must be 0). In the context of a
transmission task, it is possible to send a user data block with specification of
starting index and the length to the remote station.
While BUSY is set parameters of the module must not bee edited.
Remark:
This module is to be called from the user program once per cycle.
