IO-Link

Poin-to-Point (star) Transmission speeds: 4.8 kBit/s, 38.4 kBit/s and 230.4 kBit/s A master has a number of ports/ connections, each of which allows connection of a sensor/actuator via point-to-point connection. Star topology

Star, line and tree No terminating resistors necessary The sum total of all cable lengths in a segment may not exceed 100 m Transmission speed 167 KBit/s With a maximum of 2 repeaters it is possible to achieve a maximum extension of 500 m. No. of slaves: max. 62 AS-i bus system requires its own power supply in addition to the master and slaves.

Star, line and T-branch (T-branches with up to 6 stations per branch) Cable length without repeater max. 1200 m, with repeater up to 13.2 km, Transmission speed depends on network extension: 100 m → 10 Mbit/s 1200 m → 156 kbit/s A maximum total of 65 devices (1 master and 64 slaves) can be connected Bus components are distinguished by function into master station, local stati- ons, decentralized station, decentralized E/A station and intelligent station.
