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.

IMPORTANT
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.
