Authentication version 5. Default value is 2.
Enable Aggressive Mode in Secure Authentication
The valid selections are Enabled (Checked) and Disabled (Unchecked). Default
value is Disabled (Unchecked).
When the selection is Disabled (Unchecked), the controller disables DNP3

When the selection is Enabled (Checked), the controller enables DNP3
Aggressive Mode in Secure Authentication subsystem.
Critical Function Code in Secure Authentication
This critical function code in the DNP3 Slave configuration page is used to
define the list of the critical function codes in Secure Authentication. A critical
function code should be defined by clicking the number icon to change it
between Critical and Non-critical.
The following table shows the default state of the function codes that are
defined in Connected Components Workbench software.
