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 configured number of retries, the communications link is considered failed and a reset
sequence is required before a new primary frame could be sent.
Application Layer
Enable Application Layer Confirmation:
The DNP3 Slave Driver can be configured to retry unconfirmed
application link primary frames. The number of retries the driver sends and the retry timeout are configurable.
This service is disabled unless Application Link Confirmations check box is selected.
Application Layer Retries:
The number of Retries is configurable between 0 (Application Link Retries
disabled) and 255.
Application Layer Timeout (ms):
The Retry Timeout is configurable between 0 (Application Link Retries
disabled) and 5,000ms
Use different SEQ numbers for CONFIRM and RESPONSE:
Check to enable.
Click on the
Save
button to save your configuration. The
Apply
button will save your settings and apply them
immediately. To revert to the previous defaults, click on the

button.
Object
Mapping
Object Mapping:
When clicking on each link a dialog window appears. The dialog window is used to configure
and map every DNP3 point to a specific I/O.
Note:
Each type of I/O must have its corresponding Object
Mapping Window opened at least once, or else the I/O won’t be mapped.
