Note
Memory area allocation
● HART variables set to 0 = "non"
If all four HART variables are set to 0 = "non", no memory area for HART variables is
reserved/allocated in the input address area.
● HART variable set as not equal to 0
If at least one HART variable is not set to 0, then the complete memory area of the four
HART variables in the input address space is always allocated.
All HART variables set to 0 = "non" are automatically preset to 15 = "CiR" (0 = "non" is
inadmissible).
