IO-Link - the fieldbus-independent communication interface

IO-Link is a fieldbus-independent communication interface for sensors and actuators. 

It is based on the IO-Link specification "IO-Link Communication Specification" (Version 1.0 
November 2007) of the PROFIBUS Nutzerorganisation e.V..

IO-Link is a point-to-point connection between the sensor/ actuator and an interface module. 

Up to 

now, the binary connection was only designed for transferring switching information, but 

IO-Link now allows 2 bytes to be transferred normally in a 2.3 ms cycle via a combined 
switching status and data channel. 

Other information can be exchanged in addition to the process values, such as parameters or 
diagnostics messages. 

This enables communication with sensors and actuators down to the "last meter" to be esta-
blished for universal communication

General technical information

„

standard I/O-connection technologies in point-to-point connection, unshielded, 20 m wire 
length

„

cylcic process data transfer in typ. 2.3 ms

„

paralel service data exchange without any impact on the process data 

„

communication via 24 V-pulse modulation, standard UART protocoll

„

communication between master and device in 3 different transmission speeds
