Now, we can cover an in-depth description of cabling in PROFINET networks. PROFINET cables come in two flavors: copper and fiber optic.The factory floor, where PROFINET is most commonly used, is a rough environment with challenging environmental conditions. In that environment, standard Ethernet cables, like those you find in your office or home, might break or damage easily. For that reason, industrial Ethernet cables are a common choice. On the wire, Industrial Ethernet is just. The most common PROFINET copper cable is a 4-wire shielded, green-colored cable, which supports 100 Mbps Fast Ethernet at a distance of 100 meters.You can achieve Full Duplex transmission: meaning data can be transmitted in both directions through one cable simultaneously. Also, 8-core copper cables are available for 1 Gbps transmission rates. In o. Besides copper cables, PROFINET can also employ fiber optic cables. The PROFINET fiber optic cable's scheme consists of two parallel wires. The wires are ready for the direct assembly of connectors. Printed directional arrows help facilitate the wires' assignment to the transmit and receive connections. PROFINET fiber optic cables have speeds of up. Distance:Individual copper segments are limited to 100 m before the signal must be refreshed, for example with a switch. Fiber optic cables cover longer distances by default; some run for over 100 km long. Cost:Cost is a crucial factor when building a network. Since cable costs vary depending on the general type and functionality, you must create a.
