2.3 Module Internal Database
Central to the functionality of the module is the internal database. This database
is shared between all the ports on the module and is used as a conduit to pass
information from one device on one network to one or more devices on another
network. This permits data from devices on one communication port to be viewed
and controlled by devices on another port. In addition to data from the slave and
master ports, status and error information generated by the module can also be
mapped into the internal database.
2.3.1 HART Channel Driver Access to Database
The following illustration describes the flow of data between the HART channel
drivers and the internal database.

The HART Master driver uses the database in two ways:
A read command issued to a slave device by the master driver will return the
slave data into the internal database
A write command issued to a slave device by the master driver use the data
in the internal database to write to the slave device
In addition to data from the master HART channels, detailed status and error
information generated by the module can also be mapped into the internal
database.
2.3.2 Auto-Polling
This feature is enabled by setting the AUTO-POLL CODE (in the configuration
file) to a value of P (point-to-point) or M (multi-drop). If the value N is entered for
the parameter, the auto-poll feature is disabled. When the feature is disabled, the
channel will only execute the commands enabled in the user command list.
When the auto-polling mode is enabled, the module will automatically acquire
data from the HART instruments attached to a channel without the use of user
commands. If user commands are present and enabled when the feature is
enabled, they will also be executed independent of auto-polling.
