Global database applications include time synchronization, rapid
notification of alarm conditions, and multicasting of setpoint values
and constants to all devices in a common process. This allows uniform
and rapid transmission of global data without having to assemble and
transmit separate messages to the individual devices.
Access to a network’s global database is available only to the nodes on
that network, because the token is not passed through bridge devices to
other networks. The user’s application can determine which data items
are useful to nodes on a remote network, and forward them as
necessary.
