Information Regarding Profibus Cable Wiring

Network administrators working with Profibus cables should at all times ensure that Profibus cable wiring need to be compatible with upcoming technologies. Even though new technologies are developed with the older Profibus cable wiring systems in mind, it does sometimes happen that these newer technologies are developed independently and thus have nothing to do with the older Profibus cable wiring versions. In this case, a network administrator's Profibus cable wiring design must be able to adapt to the new technology as far as possible.

 

Different Profibus cable wiring options are available for the different applications used.

 

·        Due to double shielding, this Profibus cable wiring option is particularly suitable for industrial environments subject to electromagnetic interference.

 

·        The second Profibus cable wiring option involves grounding continuity that may be implemented through the outer casing of the bus cable – a separate drain wire is not required.

 

·        Resistance of network to interference due to double shielded cables and integrated grounding concept through the outer casing of the bus cable.

 

·        Different types of Profibus cables for a wide range of applications.

 

·        Silicone-free, thus particularly suitable for use in the automotive industry.

 

·        Time saved by simple and fast connector mounting with FastConnect cables.

 

If you were to analyze Profibus cable wiring, you will find eight individual wires that are each colour coded. At each end of the Profibus cable wiring, connectors are found which are used to secure these Profibus cable wiring. The specific order of wire placement into the connectors is determined by the cable assembly of the specific Profibus used. The Profibus cable wiring consists of blue, blue and white striped, green, green and white striped, brown, brown and white striped, orange, and orange and white striped. It should be noted that if these mentioned Profibus cable wiring are not placed into the connectors in accordance with the correct Profibus cable pinout, connectivity may be lost.
