When HART variables or the multiHART area is used, the HART area is arranged directly ush
against the QI bits of the analog inputs.
The structure of the HART area is dependent on the conguration:
• In the conguration with 4 HART variables in the input area, the area has a length of 20 bytes
and always contains 4 HART variables, each with a 4-byte value and a 1-byte quality code
(QC).
