3.1.6 Recommended Design Rules

While designing Ethernet networks special attention and caution must be taken regarding active network components.
While designing a network for line topology it is important to notice that a small delay is added with each every switch in
the line.

It is not recommended to connect more than 32 frequency converters in a line at any API. Exceeding the recommended
design rules, may result in failing communication.
