The gateway supports a single independent Client on the IP network using the
UDP protocol to interface with processors or devices using a user constructed
command list of up to 100 entries. The gateway's internal database is used as
the source for write commands to the remote units. Data collected from the
remote units using read commands is placed in the gateway's database.
2.1.1 Module Internal Database
The internal database is central to the functionality of the gateway. This database
is shared between all the drivers in the gateway 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 Client, status and error information generated by the
gateway can also be mapped into the internal database. Use this data to
determine the "health" of the gateway and to determine if commands are being
processed successfully.
