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
Disable functions in the Configuration Map table.
