With the auto-poll feature enabled, the module automatically generates the
following HART commands and stores the data in the module's database at the
user-specified location:
CMD Description
0 Read Unique Identifier
3 Read Current and Four Dynamic Variables
13 Read Tag, Descriptor and Date
14 Read PV Sensor Information
15 Read Output Information
If the unit is set for point-to-point mode, the module will automatically gather the
information for the device with the polling address (short address) of zero and
place the data into the database. Each device requires a 50-word database area
with the format shown in the following table.
