Process data
The process data of the devices are transmitted cyclically in a data telegram, whereby the process
data size is defined by the device. Process data from 0 to 32 bytes are possible for each device
(both input and output). The consistency width of the transmission is not fixed and is therefore
master-dependent.

Device data
Device data can be parameters, identification data and diagnostic information. They are exchanged
acyclically and on request of the IO-Link master. Device data can be written to the device (write) or
read from the device (read). For this purpose, the ISDU (Indexed Service Data Unit) was defined
in the IO-Link specification. The ISDU determines, among other things, whether the data is read or
