I am starting to use Modbus scanner in conjunction with user defined structure (Modbus read to structure and Modbus write from structure). Works well by creating devices one by one (see attachment 2) but if I create a new device from profile I need to manually edit each device and enter the structure I want to use. In the help file on the topic (Modbus I/O scanner configuration - App Note) there is a description of exactly what I want to do but I am unable to select a structure name when creating a new device (see attachment 1). This leads to me having to manually enter the structures for each device (see attachment 3).
I also need to add the profile for every new device I create from the profile...
What am I missing? How to I get the structure to follow the profile (if that is what's missing)? And how to I get the profile to stay the same for each new device?

You need to individually write your registers (or pairs of registers) to each member of HLS1. After doing that, "Generate Profile from Config" and you should be able to use the UDT with a new device. You also may need to populate the "New Device Name" field prior to being able to enter a UDT.

To have the option of using a UDT, every local field must be associated with the UDT. The last entry in your config references V rather than HLS1. If every field is tied to the UDT, you will be given the option to add the UDT to profile.

Thank you guys, it works like a charm now!
