Here the next example for better understanding.

Server sends 15 bits to the client (VW20) and receive 15 bits from client (VW30).

 Nice thank you a lot !

Last question. You use adress 20 and 30.

How many adress can i use ?

I don't need this for now but Im curious. Its possible to send (master 1 --> master 2) 15 bits on adress 20, 15 bits on adress 30, 15 bits adress 40, etc... ?

Like Obama: Yes you can.

You can use the two UDFs in the program as many times as the program allows for the number of free blocks.
The addressing is freely selectable, but it always a word (2 bytes). Therefore, you can also address in a distance of 2:
0, 2, 4, 6, 8 and so on .......
