Dear Vicente ,
First of all I will guide you to refer to the manual of ADAM 5510KW , where you can find some mapping table between
the KW Tags and Modbus Tags
You only need to map the Internal register of KW ( chapter 5 of the Manual ) to the realted %MX(D)(MD)3.X register
Attach I have add a small DOC file with some screenshots form KW how it can be done
If you still have further Qisetion you can contcat me via email below.
Mit freundlichen Grüßen / Best Regards / Cordialement
