3 Technical Data
3.1 Cabling Requirements
•
Choose suitable media for Ethernet data transmission. CAT5e and CAT6 cables are recommended for industrial applications. Both
types are available as unshielded twisted pair and shielded twisted pair.
•
Shielded cables are recommended for use in industrial environments and with drives.
•
A maximum cable length of 100 m (328 ft) is allowed between the switches.
3.2 Cable Specifications
PROFINET cables used are based electrically on category 5 balanced LAN cables according to ISO/IEC 11801 Edition 2.0, Class D.
Type C cables can be used in special applications (for example, the use of trailing cables and frequently moved machine parts), even
though their design and mechanical parameters can deviate from the specifications of type A and type B cables. Still, most of the
electrical parameters (for example, impedance levels) are retained.
Highly flexible copper cables generally have the finest stranded conductors and a highly resistant polyurethane outer sheath. Various
outer sheath materials are permitted to meet the various demands regarding resistance of industrial environments and exterior/
underground laying (natural and synthetic oil, grease, coolants/lubricants, chemicals, high and low temperatures, UV radiation, and so
on).
