Confirm Successful Configuration
To confirm that the DNP driver has been properly configured,
1. From the Controller menu, select DNP Status. You will be presented with the following dialog.
2. Ensure that the DNP Status field within this dialog displays 07: enabled, configured, running.
3. You can also monitor the current state of the defined DNP binary input points from the Binary-In
tab.
4. Toggle the state of digital input 1 configured earlier in this exercise and observe the event buffer
for Binary Inputs increment on each change of state. After 5 seconds has elapsed, notice that
an unsolicited DNP message is triggered to master station 200. Given that DNP master station
200 is not yet configured and connected, a response to the unsolicited message will not be
received and the 5000ms Application layer timeout period will expire. The unsolicited message
transmission will subsequently retransmitted and will be aborted after 3 retry attempts have been
made. This confirms that your outstation is properly setup and unsolicited messages are being
generated and sent. At the time of this implementation, the events will be re-attempted only after
a new event occurs.
5. Also observe the Internal Indications show that Class 1 events are available as indicated in the
figure below.
