Cyclic HART Input Data
The HART input data holds the primary variables for the “live” HART device, and other
information gathered during the normal HART scan. Additional “documentary” data is
available through the pass through message interface in the device information tables. Pass
through messages are defined in detail in the User Manual.

The HART Input Data for a channel may be zeroes if HART communications
is disabled for that channel. For more information on disabling HART
communications, refer to the Disable HART communications and HART
CMD 3 Disable functions in the Configuration Map table.
