Logix 5000 - Enet comms synchronous?

Most of us are familiar with the concept that for Logix 5000 based processors, the I/O updates asynchronously with the logic scan. But what about ethernet comms? If set up in the I/O tree, using a MSG read instruction or when being written to from a panelview or another MSG based processor?

Also asynchronous or does it depend on the type of comms?

Thanks in advance!

The above thread will answer your question.
Communications updates from unscheduled sources are asynchronous to the program scan.
