Hi Fritz, thanks for all your explanation, it really is helping.

I have one simple question that bugging me, how can we defined which address we are going to give to the DP DP Coupler.

In this case I would like to send data from Address as follows :

I 0.0 - I 0.8

O 0.4 - O 2.8

DB1 - DB4

Would you please elaborate? Thanks in advance.

And I really appreciate for your help.
