Different types of cables are available on the market when assembling
PROFIBUS networks.
Standard Siemens PROFIBUS LAN cable number 6XV1 830-0AH10 is
available from Thermo Scientific, part number 057415.
Consult the Siemens PROFIBUS network manual for additional
information relevant to wiring and available auxiliary devices (like a
repeater).
The table below indicates the maximum cable segment length admitted
according to the communication speed.
Table C–2. Maximum Cable Length of a Segment
The bus connector should be rated for the max allowed speed of the
Profibus (12 Mb) and should contain a termination resistor that can be
switched on or off. Bus connector is available from Thermo Ramsey, part
number 057416.
