I'm having some difficulties in the module configuration. Well I tried several ways to do this setup but got no results. I'm using a library available for download and manual setting available in the same site. The LED module Modbus / USS do not light the tx and rx with it I do not know where the problem is, I'm new to this type of application and am encountering many difficulties in the creation of DBs that will obtain the data.

If they have, I need an example application for this type of communication, I'm testing with equipment that communicated in other Modbus PLCs and it worked perfectly.
