Functional Specifications - HART Analog

The HART Analog Protocol exists in 4 and 8 channel implementations. This driver can be
configured on an individual channel basis to operate as a HART Master Station and
supports all the available HART commands including Universal, Common Practice and
Device Specific Commands. Each HART channel is independently configured to interface
with the internal database in the module.
The auto-poll mode allows the module to automatically collect data from each HART
instrument on the channel and store the data in the module's database without the use of
user commands. The module automatically generates HART commands 0, 3, 13, 14 and
15.
