Configure DNP Outstation
1. From the Controller Menu in either TelePACE or ISaGRAF, select DNP Configuration to
launch the DNP Configuration dialog.
2. The Application Layer configuration panel is displayed by default.
1. Under the Communication group box, change the Retries parameter to 2.
2. Leave all other parameters under the Communication group box at default values.
TIP: It is not necessary to enable the Application Layer confirmation as unsolicited events,
by their nature, request for an Application Layer confirmation.
3. Set Time Synchronization to None.
TIP: It is recommended that a DNP3 master initiate time synchronization.
4. Enable Unsolicited Class 1 events.
5. For Class 1 Events, set a Hold Time of 5 seconds and a Hold Count of 100.
TIP: On systems with multiple outstations that could potentially transmit unsolicited
messages to a master at the same time, it is recommended to use a combination of the Hold
Time and Hold Count parameters to avoid multiple stations from transmitting at the same
time.
6. Enable Unsolicited Class 2 events.
7. For Class 2 Events, set a Hold Time of 3600 seconds and a Hold Count of 10.
TIP: Class 2 events are typically of less importance than Class 1 events and may not need

8. All other parameters can be left at their default values. The completed Application Layer
Configuration panel should look like this:
