Socket Interface Using CIP Generic Messaging 483
each Write does not require an application response or
acknowledgement. The application protocol determines the exact
sequence of application transactions.
Typical Sequence of Transactions For UDP With OpenConnection
The following diagram shows a typical sequence of socket interface
transactions for UDP communications when using the OpenConnection
service to specify the destination address.
The exact sequence of sending and receiving data depends on the
application protocol.
