How to Configure SCADAPack DNP Master
In this exercise, we will configure a SCADAPack DNP Master to poll a DNP outstation with address
10. The DNP master will be communicating to the outstation by requesting for Class event data and
acknowledging receipt of unsolicited responses through com1.
After this exercise, you should be able to:
 Configure a DNP Master to poll for Static (Class 0) and Class 1 event data.
 Configure a DNP Master to accept and respond to unsolicited messages
Tasks to Complete
1. Enable DNP communication on com1 of the SCADAPack controller.
2. Configure a DNP Master with station address of 200, for example.
3. Configure the DNP master to issue class polls to the outstation created in the previous
exercise.
4. Map outstation DNP points to local DNP points.
Configuration Steps
1. Use the same procedure of the previous exercise to enable the DNP protocol on com1.
2. From the Controller menu, launch the DNP Configuration panel.
3. From the Application Layer configuration panel,
a. Ensure that the Application Layer Confirmation is Disabled.
TIP: A master should not have to request for an Application Layer Confirmation, as
an Application Layer response is implied in all master requests.
b. Set the Application Timeout to 3000 seconds.
c. Set Time Synchronization to none.
TIP: Master time synchronization to an outstation is configured in the Add/Edit
Master Poll dialog.
d. All other parameters can be left at their default values. The completed Application Layer
Configuration panel should look like this:
