x: The parameter values are not evaluated if the control bytes are 0x00.
Example
The list of detected slaves (LDS) is to be determined. This requires the parameter 0xB0 (1011 0000
bin
) to be
read.

Therefore the byte sequence 0x30 42 00 00 00 00 has to be written in the parameter data block for the
KL6224. The terminal responds with the following data:

In this example the IO-Link master should have detected the slaves with node numbers 2, 3, 6, 9, 23, 24, 25
and 31. It therefore responds with the parameter data 0x8380024C
(1000 0011 1000 0000 0000 0010 0100 1100
bin
)
The read sequence is completed with the byte sequence 0x00 00 00 00 00 00.
