IO-Link Communication Mode

2.2
The IO link communication mode is initiated by the master (PLC) with a standardized command sequence,
this sequence is called "wake-up". After successful completion of the wake-up sequence the IO link
communication starts.
Data is the most important basis for process and product optimization. With the help of IO-Link, valuable
additional data can be made accessible. Sensor and Master can exchange two different types of data (cyclic
and acyclic data).
More information can also be found here.

Cyclic data

2.2.1
Transmitted in real time. They are used for process control in the automation system. These can also be
transferred to other IT systems via IO-Link.

Acyclic data

2.2.2
Through this data stream, sensors (IO devices) can be parameterized. Additionally this data stream also
allows to transmit data for identification and analyzation. The figure below shows the different types of data
and their value for the application.
