8.1 SIMATIC NET cables for PROFIBUS PA
PROFIBUS PA cables
The following applies for PROFIBUS PA cables:
● Due to the double shielding, they are particularly suitable for laying in industrial
environments subject to electromagnetic interference.
● A consistent grounding concept can be implemented via the outer jacket and the ground
terminals of the SplitConnect Tap.
● The meter markers printed on the cable make it easier to identify the length.
(Serve as orientation; accuracy ±5 %.)
Notes on laying PROFIBUS PA cables
Bus cables are impaired by mechanical damage. How to install bus cables correctly is
described in detail in Appendix "
Installing bus cables (Page 259)".
To make it easier to measure the length of cables, they have a marker every meter.
Overview
The table below is an overview of the bus cables for PROFIBUS PA showing their
mechanical and electrical characteristics.
If you require a cable with characteristics that are not covered by the range of products
described here, please contact your local SIEMENS office.
