RS 485 cables

Introduction
The following applies to all RS 485 cables for PROFIBUS from Siemens:
● Their double shielding makes them especially suited for laying in industrial environments
with electromagnetic interference.
● A continuous grounding concept can be implemented by means of the outer shield of the
bus cable and the ground terminals of the bus terminals.
● The imprinted meter marking makes it easier to determine the length (accuracy ±5%).
RS 485 cables for PROFIBUS
SIMATIC NET PROFIBUS cables are available in different versions which allow optimum
adaptation to different areas of application:
● FC Standard Cable GP (bus cable for fixed laying inside buildings)
● FC Standard Cable IS GP (bus cable for hazardous area)
● FC-FRNC Cable GP (bus cable with halogen-free protective jacket for use inside
buildings)
● FC Food Cable (bus cable with PE jacket for use in the food and beverage industry)
● FC Robust Cable (bus cable with PUR jacket for environments subject to chemical and
mechanical stress)
● FC Ground Cable (ground cable with PE jacket)
● PROFIBUS FC Trailing Cable (trailing cable for tow chains)
● PROFIBUS Festoon Cable (bus cable for festoon mounting)
● PROFIBUS Torsion Cable (torsion-free bus cable for networking movable plant parts, for
example, robots)
● PROFIBUS FC Flexible Cable (bus cable for machine parts that are moved infrequently
or cabinet doors)
● SIENOPYR-FR ship cable (for permanent laying on ships and off-shore units in all rooms
and on open deck)
● PROFIBUS Hybrid Standard Cable (hybrid cable with 2 power wires (1.5 mm
and power supply of the ET 200pro)
● PROFIBUS Hybrid Robust Cable (trailable hybrid cable with 2 power wires (1.5 mm
data and power supply of the ET 200pro)
