According to the Ethernet/IP user manual W506 §8-5-2, you use the reset operation to make the port apply any address changes you've made (presumably via messages to the TCP/IP object for the port).

We had an issue where the port was locking up & could not work out why, so implemented a reset like this.

as it turned out, it was a configuration issue that was not obvious couple with our HMI comms method that caused the lockup.
