PROFIBUS Cable Types

The recommended cable is

 Belden 3079A PROFIBUS Cable

This is a shielded, 150 ohm twinaxial (single twisted pair) cable. It has 22 AWG

conductors and a mutual capacitance of 9.0 pF per foot, nominal. For complete

specifications on this cable, please contact your Belden dealer or visit their website at

www.belden.com.

Alternate cable types are:

 Siemens 6XV1 830-OAH10 Two Core shielded

 Siemens 6XV1 830-OBH10 w/PE Sheath

 Siemens 6XV1 830-3AH10 for underground burial

 Siemens 6XV1 830-3BH10 trailing cable

 Bosch Comnet DP #913 548 Flexible PROFIBUS cable

 Bosch Comnet DP #917 201 Trailing PROFIBUS Cable

 Bosch Comnet DP #917 202 Massive PROFIBUS Cable

Note: Allen Bradley “blue hose,” which has an impedance of 78 ohms, is not

recommended for this application.

Network Termination

Termination resistors are needed, as defined in DIN 19245 Part 1 section 3.1.2.5.

(Segment 2)

Generally, termination is provided in commercially-available PROFIBUS standard network

connectors. Some connector vendors provide termination capability in the connector and

a switch on the connector to enable/disable termination. Some connector vendors provide

both terminated and unterminated connectors.
