Abbildung 16: PROFIBUS Network
Up to 32 PROFIBUS devices can be connected to one bus segment. If
several bus segments are linked to each other with repeaters, there can be
up to 127 devices on the network.
The maximum length of a bus segment depends on the baud rate used.
Only PROFIBUS certified cable, preferably the cable type A, should be
used.
