Point-to-point connection at the field level

IO-Link is a standardised IO technology (IEC 61131-9) for communicating with both sensors and actuators. This powerful point-to-point communication is based on the familiar three-wire sensor and actuator connection, making no further demands on the cabling. As such, IO-Link is not a fieldbus but the further development of the existing, proven connection technology for sensors and actuators.

Valve terminals from Festo are port type B devices with galvanically isolated electronics and valve power supply. They communicate via the IO-Link protocol 1.0, can use all three COM modes and process inputs and outputs of up to 8 bytes.
