If you look in the Help file (in U90 ladder) you will find all you need.  In the main index Content\Communications.  And in Examples\Modbus\Modbus Master for an example.

Believe it or not, Help files are an excellent primary source of information, and where we all got the knowledge from in the first place.  If you have further questions once you've built your own program based around the examples then we are glad to help.

cheers, Aus
