Party Line with branch and drop
The PROFIBUS DP realized with PDP21
or PDP22 represents a real Party Line
topology that supports high baud rates
up to 12 Mbit/s best possible.
Branches and Drops cause reflexions
which results in a dramatic reduction of
the max. baud rate.
With repeaters, this influence can be
equalized partially.
