Confirm Successful DNP Master Configuration
With this configuration and a valid communication link between com1 of the DNP Master and com2
of the DNP outstation, you can use the DNP Master Status dialog to see communication activity
between the two devices.
Confirm that you have communication activity between the master and outstation as indicated in the
screen capture below.
If the All Stations tab indicates successful message transmission between the Master and Outstation,
congratulate yourself on completing the exercise.
For additional information on the aforementioned configuration parameters, referenced in the
previous two exercises, refer to Chapter 0 in this manual.
How to Configure SCADAPack Address Mapping
At this stage in your configuration, the DNP master is able to poll for all outstation points. After a
successful poll, you can verify the status of current value of outstation DNP points from the various
data point type tabs available across the DNP Status Window.
The figure below shows the status of DNP digital input points 0, 1 and 2 on outstation 10.
The Modbus Address column is blank as these remote DNP points have not been mapped to any
local Modbus registers.
While this data is available in the DNP Address space of the master, it is not available for use within
a local program. To render DNP data available to a local program, you would have to perform an
Address Map. To map DNP binary input data from outstation 10 to this master’s local DNP
database, do the following:
From the Controller menu, select DNP Configuration.
1. Click on the Address Map tree node.
2. From the Address Mapping configuration panel
a. Click on the Add button to launch the Add/Edit Address Mapping dialog.
b. Enter 10 for Station.
c. Select Binary Input for Object Type.
