Definitions of error cases
Bit 4
0
Error on a port of the IO-Link Master
1
Error on an IO-Link device
Bit 0 to 3 indicate which port the defective device
is connected to.
2
Error on IO-Link Master
In this case bits 0 to 3 have no significance, since
the error affects the entire IO-Link Master, as for
example “with undervoltage”.
