AuthenticationFlag
Summary Returns the network variable’s default authentication
setting , which is specified by the device developer. If this
property is set to True, the network variable uses
authentication by default.
You can override the default setting by writing to the
UseAuthenticationFlag of the ConnectDescTemplate object
used by the connections involving the network variable.
Note: If you set the UseAuthenticationFlag property to True,
then all devices participating in the authenticated connection
must also have authentication enabled. This means that the
AuthenticationEnabled property of each AppDevice involved
in the connection must be set to True.
