Parameters, diagnostics messages and address space
A.6 Address space
Address space
The following tables show the allocation of the address space of the I/O module.
The addresses for the HART variables or the addresses of the multiHART range are only available
if the HART variables or the multiHART range were configured/parameterized.
Output area
If the HART variables or the multiHART range are configured or parameterized, then HART
variables or the multiHART range begin directly after the value status, i.e. from IB x + 1.

The structure of the HART range is dependent on the configuration:
• With the configuration with 4 variables, the range is 20 bytes long and always contains 84
HART variables, each with 4 bytes value and a byte quality code.
