Control and Field Device level.

$2.$ Setpoints, ladder programs, and general information are sent on a$($n$)$ level network.

$3.$ Real$-$time $\frac{\text{I}}{O}$ is transferred on $a(n)$ level network.

$4.$ The advantage of $a(n)$ level network is ease of installation and reduced $\frac{\text{I}}{O}$ wiring.

$5.$ A key characteristic of a network used for real$-$time $\frac{\text{I}}{O}$ is

$6.($protocol$)$ guarantees data is delivered complete and without errors on an Ethernet network while $($protocol$)$ decodes the source and destination address of the message.

$7.$ EtherNet$/$IP adds $($protocol$)$ to the Ethernet protocols to produce a network suitable for use on automation and control level.

$8.$ EtherNet$/$IP has approaching that of a traditional control network.
