Introduction
The following is a look at the basic configuration techniques for the DNP 3.0 protocol suite including
B023-0, B015, and B013 applications. For more detailed configuration techniques and functional
information, please refer to the configuration guides and functional specifications.
Assumptions
1. Your firmware has B023, B021, B015, and B013 loaded.
2. You have taken DNP 3.0 configuration training.
3. You understand the basic architecture of the GE product.
D2X Platform Architecture
To configure DNP 3.0, you must understand the relationship between a DPA, DCA, DTA, and system
point database.
Data Processing Application (DPA)
The data processing application (DPA) in general reports data from the system point database memory
registers to a master. It can sort and filter data going back to the master by configuring point mapping
tables. A few examples of the many DPAs available are DNP 3.0, MODBUS, or IEC protocols.
·
·
Filtering: Selecting points you want to return to the master and skip the others.
Sorting: Grouping the points to be reported.
Remember: DPAs cannot own points; they are merely mapped to a DCA or DTA-owned point.
Data Collection Application (DCA)
The data collection application (DCA) collects data from external devices and writes it to the system point
database memory registers. It can pass controls, time-synchronize devices, and poll as many devices as
connected for that protocol (you do not need a DCA per device). A few examples of the many DCAs
available are DNP 3.0, MODBUS, or IEC protocols.
Data Translation Application (DTA)
The data translation application (DTA) does not communicate to devices or respond to master requests. It
be mapped to read points in the system point database memory registers and write to other points in the
system point database memory registers. Some examples of DTAs are Calculator, Mailbox, and
LogicLinx™.
System Point Database (B008)
The system point database allows you to reserve the 16-bit memory registers in NVRAM on the D2X
platform and assign them to DCAs.

Configuring the System Point Database
As with any DCA, you start by setting up the system point database.
Opening the System Point Database
The system point database allows you to enter the number of points required by the device in the field, as
well as the points required by the B023-0 application (known as pseudo points).
Golden Rule #1
Each DNP 3.0 DCA (B023-0) version requires a different number of pseudo points. Please refer to your
version-specific configuration guide appendix on pseudo point configuration. If you enter an incorrect
number of pseudo points, you may encounter the following error in the wesmaint error log: “Insufficient
wesdac <x> points expected <n>”.

Page 5 of 23
Enter the number of global, real, and per device pseudo points. (Please refer to your configuration guide
for an explanation of these terms). In our case, for version 409 of B023, we must calculate the number of
points to enter.
37 digital input points:

·
Three global pseudo points (referring to the configuration guide)
Four real points (referring to figure 1 DNP 3.0 device number one)
13 per device pseudo points (referring to the configuration guide)
Four real points (referring to figure 1 DNP 3.0 device number two)
13 per device pseudo points (referring to the configuration guide)
12 analog input points:
·
·
·
·
One real point (referring to figure 1 DNP 3.0 device number one)
Five per device pseudo points (referring to the configuration guide)
One real point (referring to figure 1 DNP 3.0 device number two)
Five per device pseudo points (referring to the configuration guide)

Configuring the Data Link
Golden Rule #2
Always configure your data link (B013) application before you configure the DPA and DCA applications
(B023-0 and B021-0) and finally your Bridgeman (B015) application.
The data link (B013) application is used to configure your RS232 / 485 communications ports with specific
parameters, and give that configuration a data link channel number.
Opening the DNP 3.00 Data Link
The tables available to be configured in the data link are displayed below.

The Tables in the DNP 3.00 Data Link
We will focus on the basic configuration of the Port Configuration table.
For the example in figure 1, we configure the Port Configuration table to have three ports (COM 1, 2, and
5). This reflects the physical hardware ports we want to use in our system. The end configuration looks
similar to the following screen:

The Port Configuration Table
Golden Rule #3
The numbers in the Config column are used as the data link channels in the Bridgeman (B015)
application LAT and RAT tables. For example, config 0 in the B013 Port Configuration table is the same
as data link channel 0 in the B015 LAT and RAT tables.

Configuring the DNP 3.0 DCA
The DNP 3.0 DCA application allows you to mirror the DNP 3.0 device you intend to poll for data and
configure specific polling parameters. In this example, the configuration relates directly to the two devices
displayed in figure 1. Each device has a unique address and physically has four digital input terminals
and one analog input terminal.
Opening the DNP 3.0 DCA
The DNP 3.0 DCA (B023-0) has three tables that can be configured to mirror your device in the field and
set up the desired polling scheme. This example focuses on the device setup including points and
addresses.

Device Point Map Table
The first table to configure is the Device Point Map table. In the system point database memory registers,
we have set up four digital inputs and one analog input for both devices. Because both devices have
identical point counts and types, we only have to account for them once in the table. We map them twice
in the next step to allow for all points to be collected from both devices.
For information about the other fields in this table, please refer to your configuration guide and functional
specification.

Device Configuration Table
This example focuses on setting the address and linking the Device Point Map table. For information
about the other fields in this table, please refer to your configuration guide and functional specification.
The following example shows how to configure the DNP 3.0 DCA (B023-0) application for the desired
addresses of the two devices in figure 1.
The Device Configuration Table
After the addresses are set, we link the Device Point Map table to this Device Configuration table using
the device configuration map at the end of this table.

The Start field at the bottom of the window shows the start of your selection, and the # of Recs field
reflects the quantity of points you selected. In this case, it starts at point record 1 and has a total of two
records. Click OK.
Now that you have mapped the points for device 1, repeat the steps to map the points for device 2.

DCA Configuration Table
The last table in the DNP 3.0 DCA (B023-0) you need to configure is the DCA Configuration table. This
example focuses on the DNP 3.0 DCA addressing and linking the two logical devices (devices 1 and 2 in
figure 1) we created to that address.
To set the address to which the devices will report, in the case in figure 1, you enter address 10. This
gives the DNP 3.0 DCA an identifiable unique address.
The DCA Configuration Table
To link the two logical devices we configured, navigate to theFirst Device Entry cell at the end of the DCA
Configuration table.

Configuring Bridgeman
Bridgeman is the “network” layer of the DNP 3.0 suite and allows you to map communication ports set up
in the data link (B013) to the devices set up in DNP 3.0 DPA (B021-0) and DNP 3.0 DCA (B023-0).

The Tables in Bridgeman
Configuring Bridgeman for the example in figure 1 requires that you set up the Local Application table
(LAT) and the Remote Application table (RAT). Think of these tables as one-way streets for information.
