Recommended Design Rules

While designing Ethernet networks special caution regarding active networks components must be
taken.
While designing a network in line topology it is important to notice that a small delay is added with
every switch in the line.
For EtherNet/IP the maximum number of drives in a line is dependent of the API speed of the
connected scanner:
According to the graph above, the network should thus be segmented with the use of external
Ethernet switches.
It is not recommended to connect more than 32 drives in a line at any API.
