Should an HMI be able to read and write to a variable declared as a REFERENCE TO type. I have a variable declared as such, FVNR_REF: REFERENCE TO FVNR_DUT;
FVNR_DUT is a user defined type with a few bool and interger members. In the program I am referencing FVNR_REF to another variable of the same type. Program compiles and downloads fine. Problem is my HMI cant read or write to FVNR_REF members. All other tags not of the REFERENCE type read/write just fine.

Thanks in advance for any help.
