module.

multiHART range

Definition
You can access any of the configured HART variables in the I/O module via the multiHART range.
When HART mode is enabled, the I/O module cyclically reads the variables provided by the
connected field devices itself and makes them available in the configured input address space.
You can request and read one of these HART variables via the multiHART range.
