Profibus Interface Option
10
2.7 COMMUNICATION RATE/CABLE LENGTHS/CONNECTORS
Shielded twisted pair two wire cable is required for the PROFIBUS Interface Connection.
The characteristic impedance of the cable should be in the range between 135 and 165
Ohms (3 to 20 MHZ), the cable capacity (conductor-conductor) should be <30 pF/M and
the conductor area should be 0,34 mm
2 . The 9 pin din connector on the option board is
used for all PROFIBUS connections.
