Data Link and Application Layer
Use Local Station Number as This Station DNP Address: DNP address for the slave. This value can be set by the user or
automatically assigned by the Add‐On. If the check box Same As station Number is selected, then the DNP Address will
be equal to the Station Number.
Enter Station DNP Address (Required): Enter the address for this Station if not being automatically assigned.
Min Response Delay (ms) (Required): This is the time delay in milliseconds (from 0 to 65535 msec) before sending the
response from the slave.
Enable Self Address: The DNP V3.00 Slave Driver can be configured to send its own DNP Address when a DNP Master
asks for it. When this box is checked, if a message is sent with the Self Address (65532) in the destination address field,
the will respond with its unique individual address. This feature simplifies the commissioning, troubleshooting and
maintenance of devices with an unknown address. If this feature is not enabled, the station will ignore the messages
sent to the Self Address.
Enable Data Link Confirmation: The DNP V3.00 Slave Driver can be configured to retry unconfirmed data link primary
frames. The number of retries the driver sends and the retry timeout are configurable.
This service is disabled unless Data Link Confirmation option is set to Yes.
Data Link Retries: The number of Retries is configurable between 0 (Data Link Retries disabled) and 255.
Retry Timeout (ms): The Retry Timeout is configurable between 0 (Data Link Retries disabled) and 5000ms
Note: The Driver's Data Link Layer will attempt to retry (will resend) an unconfirmed data link primary frame when the
confirmation has not been received within the configured timeout. If the confirmation fails to arrive after the config‐
ured number of retries, the communications link is considered failed and a reset sequence is required before a new pri‐
mary frame could be sent.
