Application Layer Protocols

PROFINET devices are capable of acting as a server, responding to requests sent via any of several different
protocols. They are also capable of acting as a client, sending requests to other servers using any of several
different protocols. The exact set of protocols that are enabled/used will depend on which modules are
installed, how they are configured, and the details of the application program that is running.
