A.7 Address space
HART range
When HART variables or the multiHART area is used, the HART area is arranged directly flush
against the QI bits of the analog inputs.
The structure of the HART area is dependent on the configuration:
● In the configuration with 8 HART variables in the input area, the area has a length of 40
bytes and always contains 8 HART variables, each with a 4-byte value and a 1-byte quality
code (QC).
● In the configuration with 1 multiHART area in the input/output area, the area has a length
of 6 bytes:
Output range
In the configuration with a multiHART area, there is one byte in the output area.
QB x
Evaluating HART variables
If you have configured (mapped) HART variables for the I/O module, then 8 HART variables
with 5 bytes each are stored in the input address space.
Each HART variable consists of a 4-byte real value and a 1-byte quality code. The quality code
describes the validity of the value, see section HART variables (Page 32).
