With this wiring formation, there is no distinction between the trunk line and
branch lines. Wiring can be performed without restrictions as long as the total
cable length per segment is no longer than 200 m. There is also no limit in the
number of branches.
The Cables that can be used and the required baud rates are automatically
determined by whether a trunk line-branch line formation or an unrestricted
wiring formation is used.
The following table shows the conditions and restrictions for each formation.
