X2 PROFINET

Data Transmission Rate and Cables
For PROFINET, you require a data transmission rate of 100 Mbit/s (Fast Ethernet). The interfaces
are designed for full-duplex mode; in other words, the ports can both transmit and receive. For
data transfer purposes you can use electrical twisted copper cables (twisted pair, 4-wire,
100Base-T):
• The transmission characteristics of these cables must meet the requirements of CAT5.
• The maximum length of the connections between the end device and network component
or between two network components (e.g. switch ports) must not exceed 100 m.
