Application Layer Configuration
The Application Layer property page is selected for editing by clicking Application Layer in the tree
control section of the DNP Settings window. When selected the Application Link Layer property
page is active.
Application Layer parameters are set in this property page. Each parameter is described in the
following paragraphs.
The Communication section of the dialog contains the configurable application layer
communication parameters.
When the Application Confirmation feature is enabled, the SCADAPack controller requests a
confirmation from the master station for any data transmitted. When it is disabled, the controller does
not request a confirmation from the master station and assumes that the master receives the data it
sends successfully. However if the data includes event data (including unsolicited messages), the
controller requests a confirmation from the master regardless of whether this feature is enabled or
disabled. Valid selections for this parameter are:
 Enabled
 Disabled
