11.2.1.10 Events Triggered by the IO-Link Master
Events on the IO-Link master or its ports are reported by the IO-Link master to the Ether-
CAT® slave, which forwards this to the EtherCAT® master in the form of diagnostics.
The following values are set in the event qualifier:
TYPE = 2 (Warning) or 3 (Error)
MODE = 2 (Event disappears) or 3 (Event appears)
SOURCE = 1 (Master/local)
The following table lists the IO-Link event codes associated with IO-Link master events
and provides information on how to remedy faults.
