2.2 Profibus cable
Profibus devices are connected in a bus structure. Up to 32 stations (master or slaves) can be
connected in one segment. The bus is terminated by an active bus terminator at the beginning and end
of each segment (see figure 2-1). To ensure error-free operation, both bus terminations must always be
powered. When more than 32 stations are used, repeaters (line amplifiers) must be used to connect the
individual bus segments.
The maximum cable length depends on the transmission speed and cable type (see table 2-4). The
specified cable length can be increased by the use of repeaters. The use of more than 3 repeaters in
series is not recommended.
