If the Use IP List parameter is set to YES, the module will only accept a
connection from one of the three IP addresses listed, as in the example above.
The following illustration shows that the Server will accept a connection from
Client A, whose address is on the list, but will reject a connection from Client B,
whose address is not on the list.
Common ASDU Address
At the application level, the module is identified by the Common ASDU
(Application Service Data Unit) Address. This address must match the CASDU
sent by the Client unit. An ASDU is a data unit that transfers information objects
between the Client and the server.
