ControlNet

Due to the unique physical layer, common network sniffers such as Wireshark cannot be used to sniff ControlNet packets.

The repeaters do not utilize network node numbers and are available in copper or fiber optic choices.

ControlNet is a scheduled communication network designed for cyclic data exchange.

It includes synchronization and a means of determining starting node on the next unscheduled data transfer.

Both the scheduled and unscheduled phase use an implicit token ring media access method.

The maximum size of a scheduled or unscheduled ControlNet data frame is 510 Bytes.
