If the module is used as a DNP slave device, it responds to requests from a
remote DNP master device. All data in the module's database is available to the
remote master device for read and write requests.
The module provides a Configuration/Debug port for use with an external
computer executing a terminal emulation program. The terminal emulation
program provided with the module permits uploading and downloading of the
configuration information required by the module. Additionally, the
Configuration/Debug port provides a view into the virtual database,
communication statistics, and the configuration. Refer to Diagnostics and
Troubleshooting for a full discussion of this port's functionality.
5.4.1 Database Information
Central to the functionality of the module is the database. This database is used
as the interface between remote DNP devices and the Flex I/O bus. The content
and structure of the user data area of the database is completely user defined.
The following illustration shows the general format of the module’s database.
