Ok, now it is 2 years ago........
I have used J1939 function blocks - so far, so good.
But now I have to send this messages to another controller,
means: reading PGN and send the 8byte-array to another controller.
I will use for each PGN another ID and so on.
But now I can't use the danfoss function library, because it is closed and I can't get the array of 8 bytes.
So I have to write my own modules and delete the danfoss modules.
I wish, the would open their modules for reading and perhaps for modifying. They could make a automatic notice, so everybody could see, that this module is changed by the software-engineer.
