  1- make sure the I/O Channel (or CHARM) is set for HART
  2 - know which attributes are at which HART parameter (for example for coriolis mass flow meter the HART_PV could be set to mass flow, HART_SV could be set to Temperature and HART_TV set to Density)
  3 - when you make the DST, from the dropdown menu select the hart variable of your choice (HART_PV, HART_SV, HART_TV, HART_FV). Remember that HART parameters can update much more slowly based on a variety of factors.
  4 - the L-TYPE of your Analog In function block needs to be set to Direct.
