1.1 Module Internal Database

The internal database is central to the functionality of the module. 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/network to

be viewed and controlled by devices on another port/network.

1.2 DNP Master Database Layout

Central to the functionality of the DNP driver is the database. This database is

used as the interface between remote DNP devices and the other protocol

implemented on a module. 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:

DATA AREA DATA SIZE

BINARY INPUTS 1 WORD PER 16 POINTS

ANALOG INPUTS 1 WORD PER POINT

COUNTER DATA 2 WORDS PER POINT

BINARY OUTPUTS 1 WORD PER 16 POINTS

DNP DATA

ANALOG OUTPUTS 1 WORD PER POINT

The first word of the module’s database contains the first 16 points of binary input

data (if defined). It is important to understand how the data is mapped to the

database so that it can be accessed by the other protocol. Each DNP data type

has a fixed size. This size is used in conjunction with the number of points

configured for the type to determine the size and location in the database. The

following is an example of a user database with a defined set of point counts:

DATA AREA REGISTERS CFG VALUES

BINARY INPUTS 0 TO 1 2

ANALOG INPUTS 2 TO 51 50

COUNTER DATA 52 TO 71 10

BINARY OUTPUTS 72 TO 73 2

DNP DATA

ANALOG OUTPUTS 74 TO 113 40
