8.4 Program module WDC_SEND_FLEX_Px

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.
