IO-Link Interface and System Specification

IO-Link

Description:

IO-Link defines a fieldbus-independent communication interface for intelligent sensors and actuators in factory automation. The scope of this specification work focuses on the transmission physics (electrical and mechanical properties, topology), sensor/actuator communication with the IO assemblies, and a neutral data interface to the higher-level communication system. IO-Link allows an inexpensive point-to-point connection between sensor/actuator and the I/O assembly for the "last meter to the process". Diagnosis and parameter information between sensor/actuator and the automation system will be exchanged with IO-Link in addition to the measurement signal through the specified communication mechanism, thereby maximizing the performance of state-of-the-art intelligent sensors and actuators.
