This section defines the monitored single-point database. This information is
sourced from the database and is transferred to the remote Client unit. Each
point indicates one of two states, 1 = Bit On, 0 = Bit Off.
This section takes the following parameters:
 Point #
 DB Address
 Group(s)
 IV DB Bit
Each point is one bit and the DB address value corresponds to the bit offset in
the module memory database. For additional information on how to set these
parameters, see the Reference chapter of this manual.
